n.) administration of mice with c-di-GMP induces recruitment of monocytes and granulocytes [20] and activates the host immune response [21] and [22]. In one study, the lungs and draining lymph nodes from mice intranasally selleck chemical treated either with c-di-GMP

or phosphate buffered saline (PBS) were examined 24 or 48 h after treatment for differences in cell number or composition. Results showed that the draining lymph nodes of c-di-GMP-treated mice had significantly higher total cell numbers as well as higher percentages of CD44low cells and CD86 positive cells. In the lung, however, the picture was less clear with no difference in total numbers of monocytes or neutrophils or pulmonary DCs as determined by flow cytometry [21]. However, there was some indication that c-di-GMP did affect lung parenchymal cells in that the lungs from c-di-GMP-treated mice had a larger proportion of alveolar macrophages which were newly recruited (CD11chiMHCIIlowCD11b+). Also, DCs (CD11chiMHCIIhi), although not significantly increased in number, expressed higher levels of CD40 and CD86 than PBS-treated control mice [21]. Work from our own laboratories has indicated that 24 h after a single i.n. administration of c-di-GMP, there is a significant increase in the number of pulmonary DCs with higher expression

of CD40 and CD80 but not CD86 or MHCII [23]. The treatment also induced a rapid but transient recruitment of neutrophils and other inflammatory Akt inhibitor cells into the bronchoalveolar space [23] and increased levels of CHIR 99021 proinflammatory cytokines and chemokines IL-12p40, IL-1β, IL-6, keratinocyte derived chemokine (KC), MCP-1, macrophage inflammatory protein (MIP)-1β, RANTES and tumor necrosis factor (TNF)-α in a dose-dependent manner [22]. A number of recent studies have shown that the innate immune response elicited by c-di-GMP is a potent immunomodulator for the treatment of bacterial infections. In this regard, studies of the effect of c-di-GMP on the course of bacterial infection have clearly shown a striking protective

effect of c-di-GMP administration against a number of serious bacterial infections. Using a mouse model of mastitis, Karaolis and co-workers showed that, despite no direct bactericidal activity, c-di-GMP co-administered with S. aureus directly into the mammary glands significantly decreases bacterial burdens [24]. Previous work by the same group had shown that c-di-GMP inhibits biofilm formation of the same S. aureus strain as well as its adherence to HeLa cells [25]. To rule out the possibility that the c-di-GMP-mediated protection is solely due to its role in the inhibition of biofilm formation, subsequent work showed that pretreatment with c-di-GMP 12 and 6 h before intramammary infection with S. aureus also results in a 1.5 log and a 3.

Its global ocean configuration used in both versions of the coupled climate model is known as ORCA2. It has a tripolar, quasi-isotropic grid: a combination of an isotropic Mercator grid south of 20 °N, and a non-geographic quasi-isotropic grid north of it, in which the North Pole singularity is replaced by a line between points in Canada and Siberia. A nominal resolution of 2° at the equator is chosen to which a latitudinal grid refinement of 1/2° is added in the tropics. ORCA2 uses realistic bottom topography and coastlines, derived from Smith and Sandwell (1997) up to 60° of latitude and ETOPO5 elsewhere. The maximum depth of 5000 m is spanned by 31 z-levels ranging from 10 m in thickness in the

upper 120 m to a maximum of 500 m at the bottom. Vertical mixing is computed VX809 from

a turbulence closure scheme based on a prognostic vertical turbulent kinetic equation (TKE scheme), which performs well in the tropics ( Blanke and Delecluse, 1993). Lateral diffusivity is parameterized by an iso-neutral Laplacian operator with an eddy diffusivity coefficient of 2,000 m2 s−1. In addition a bolus velocity is applied on temperature and salinity ( Gent and McWilliams, 1990) with the NEMO default of a spatially and temporally varying coefficient (calculated from the local growth rate of baroclinic instability and, between 20°N and 20°S, forced to decrease to vanish at the Equator), as described in Treguier et al. (1997). Lateral viscosity is parameterized by a horizontal laplacian operator and an eddy viscosity coefficient of 4.104 m2 s−1 Belnacasan in vivo except in the tropics where it reduces to 2.103 m2 s−1 (except along western boundaries) (). The ocean model is coupled Mirabegron to the LIM-2 sea-ice model ( Timmermann et al., 2005), which is unchanged in all simulations considered in

this study. In spite of these common aspects, IPSL-CM4 and IPSL-CM5A ocean component has evolved from OPA8 (Madec et al., 1999) to NEMOv3.2 (Madec, 2008) respectively, which implies the implementation of several additional parameterizations related to bottom topography and vertical mixing, as described in the following section, as well as the use of a state-of-the-art biological model, PISCES. The PISCES model is derived from the Hamburg Model of Carbon Cycle version 5 (HAMOCC5) (Aumont et al., 2003). A detailed description of the model parameterizations can be found in Séférian et al. (2012). The coupled simulations combine the OPA oceanic component to the LMDZ4 (Hourdin et al., 2006) for IPSL-CM4 or LMDZ5A atmospheric model (Hourdin et al., 2012) for IPSL-CM5A. Evolutions between these two models are described in detail in Hourdin et al., 2012). In terms of resolution, given the increasing recognition of the role of the stratosphere in controlling some aspects of the tropospheric climate (e.g. Nikulin and Lott, 2010), priority has been given to vertical resolution increase (from 19 to 39 levels) rather than horizontal resolution.

É desejável Etoposide que estas colheitas sejam realizadas nas primeiras horas, antecedendo a toma de antibióticos. Também neste ponto se constaram limitações na abordagem praticada, existindo uma proporção significativa de casos nos quais não foram obtidas culturas nas primeiras 24 horas. De acordo com os objetivos estabelecidos

nas recomendações internacionais, a antibioterapia deve ser iniciada precocemente, idealmente na primeira hora nos casos de sépsis grave ou choque séptico8. Neste estudo verificámos tempos alargados para a primeira prescrição de antibiótico, geralmente ultrapassando as 6 horas. Em parte, este atraso será consequência do modelo de funcionamento do SU, tratando-se de um aspeto que tem sido alvo de otimização através da implementação de um protocolo de atuação (Via Verde da Sépsis)14. O tempo de permanência no SU até ao internamento rondou as 10 horas. Considerámos que este seria um aspeto determinante na avaliação realizada, uma vez que tempos superiores de permanência no SU representam muitas vezes atraso na administração de antibióticos e deficiente monitorização dos doentes, com impacto MDV3100 negativo na mortalidade e na demora de internamento15.

Tendo em conta que as situações de sépsis podem evoluir rapidamente para formas mais graves, necessitando de monitorização e avaliação regular do aparecimento de sinais de falência de órgão, torna-se desejável que estes doentes permaneçam no SU por um período mínimo

para a abordagem diagnóstica e terapêutica imediatas, devendo ser internados com a máxima brevidade. A opção por uma enfermaria convencional nearly ou por uma unidade de cuidados intensivos ou intermédios dependerá da estratificação da gravidade. A origem desta demora reside provavelmente no modelo de funcionamento do SU e no fenómeno de sobrelotação dos serviços, um fator reconhecidamente associado a piores prognósticos16 and 17. A taxa de mortalidade obtida, de 30%, é significativamente superior ao valor global do serviço e está de acordo com os valores reportados na literatura. No trabalho de Rangel-Fausto et al.2, a mortalidade aos 28 dias foi de 16, 20 e 46% para sépsis, sépsis grave e choque séptico, respetivamente. Valores semelhantes foram encontrados no estudo multicêntrico francês de Brun-Buisson11, variando entre 19- 54%. Estes dados reforçam o conceito de que a progressão da sépsis para os estádios mais avançados reflete um gradiente de mortalidade crescente18. Teria sido importante estratificar os doentes de acordo com a severidade da sépsis e determinar a taxa de mortalidade para cada subgrupo.

S5). CNTNAP2

hybridization signals were observed in layers II–VI in both V1 and V2 at P0 ( Fig. 5). CNTNAP2 hybridization signals in layers II, III, IVc, and VI in V1 were stronger than in other layers ( Fig. 5). In adulthood, CNTNAP2 hybridization signals were observed in layers II–VI in both V1 and V2, although signals in layer VI were higher in V1 than V2 ( Supplementary Fig. S5). CMIP hybridization signals were observed in layers II–VI in both V1 and V2 at P0 ( Fig. 5). CMIP hybridization signals at P0 were particularly strong in layers II, III, IVc, and VI in V1, and layers II, III, and VI in V2 ( Fig. 5). CMIP expression levels were lower in adulthood than P0, but detected in layers II, III, Talazoparib solubility dmso and VI in V2, and layers II and VI in V1 ( Supplementary Fig. S5). ROBO1 hybridization signals were observed in layers II, III, and VI in V1, and in layers II, III, V, and VI in V2 at P0 ( Fig. 5). ROBO1 hybridization signals in layers II and III were higher in V2 than in V1 ( Fig. 5). By contrast, ROBO1 hybridization signals were not observed in V1 or V2 in adulthood ( Supplementary Fig. S5). KIAA0319 hybridization signals were observed in layers II,

III, V, and VI in both V1 and V2 at P0 ( Fig. 5). KIAA0319 hybridization signals in layers II and III were higher in V2 than V1 ( Fig. 5). By contrast, KIAA0319 hybridization signals were not detected in adulthood ( Supplementary Fig. S5). DCDC2 hybridization signal Orotidine 5′-phosphate decarboxylase was not detected in V1 or V2 selleck at P0 or adulthood ( Fig. 5 and Supplementary Fig. S5). FoxP2 hybridization signals were observed in layers V and VI in the primary auditory cortex at P0 (Fig. 5), but signals were very weak in adulthood (Supplementary Fig. S5). FoxP1 was expressed in layers III–VI at P0 and adulthood (Fig. 5 and Supplementary Fig. S5). CNTNAP2 hybridization signals were observed

in all layers at P0 and adulthood (Fig. 5 and Supplementary Fig. S5). CNTNAP2 expression levels were higher in layers II and IV than the other layers at P0 (Fig. 5), and CNTNAP2 was broadly expressed throughout all layers in adulthood (Supplementary Fig. S5). CMIP hybridization signals were observed in all layers at P0, although the signal in layers II and IV were higher than other layers (Fig. 5). CMIP hybridization signals were observed in layers II–VI in adulthood, with higher signal in layer II than other layers (Supplementary Fig. S5). ROBO1 was expressed in layers II–VI at P0 (Fig. 5), with reduced expression levels in adulthood (Supplementary Fig. S5). ROBO1 was more highly expressed in layer II than the other layers at P0 (Fig. 5). KIAA0319 hybridization signals were observed in layers II–VI at P0 (Fig. 5), but not in adulthood (Supplementary Fig. S5). DCDC2 hybridization signal was not observed in the primary auditory cortex at P0 or adulthood (Fig. 5 and Supplementary Fig. S5).

There, the observed chlorophyll concentration, as well as the one simulated in CM5_piCtrl, is lower than 0.05 mg/m3 (e.g. Séférian et al., 2012). As

a result, less heat is trapped in the surface layer in these areas in CM5_piCtrl as compared to CM5_piCtrl_noBio, explaining the cold surface anomalies seen on Fig. 4. Coastal upwellings in equatorial regions, on the other hand, are relatively rich in chlorophyll, and one would expect a net surface warming in CM5_piCtrl as compared to CM5_piCtrl_noBio. This is what is found by Lengaigne et al. (2006) and Patara et al. (2012), two independent studies using similar twin experiments with another coupled climate model and the same oceanic component as ours, namely NEMO. Yet, in our case, the warming effect is very weak or absent (Fig. 4). At mid to high latitudes, previous studies (e.g. Lengaigne et al., 2009 and Manizza, 2005) PI3K Inhibitor Library mw have suggested that bio-physical feedbacks would result in an intensification of the seasonal cycle: in summer, the presence of phytoplankton Bafetinib datasheet increases the surface warming, as more heat is trapped at the ocean surface, while in fall and winter, the deepening of the mixed layer acts to bring

the underlying anomalously cold layers to the surface. This is indeed the case in our simulations for the Southern Ocean and the subpolar North Atlantic and North Pacific that are marked by a warming in local summer in CM5_piCtrl (Fig. 4, right panel), and a moderate to strong cooling in winter (Fig. 4, middle panel). Consistently, the seasonal cycle of SST at mid to high latitudes is slightly enhanced in CM5_piCtrl as compared to CM5_piCtrl_noBio (Fig. 5). Note however that the physical parameterization changes Orotic acid described in Table 1 induce much stronger changes to the seasonal cycle amplitude in CM5_piStart compared to CM5_RETRO than to CM5_piCtrl_noBio (Fig. 5).

Such effect can hardly be seen in forced mode (Fig. 3) and might thus be due to air-sea interactions. In annual mean (Fig. 4, left), ice-free areas at northern high latitudes experience a cooling in CM5_piCtrl as compared to CM5_piCtrl_noBio, which again differs from earlier studies, in particular Lengaigne et al. (2009). These authors have argued that warming associated to phytoplankton blooms occurs concomitantly with the ice retreat along the Arctic coastal shelves in spring and this mechanism is then amplified in summer due to a larger reduction of sea-ice thickness and concentration. In our model, such biologically-induced warming occurs indeed in summer but its global effect is largely counteracted by the winter cooling. Fig. 6 shows the adjustment of the model to the biogeochemical component, helping to understand differences with previous model versions: during the first decade (left panel), the anomalous vertical temperature profile is close to what is expected from the one-dimensional adjustment described above, and broadly agrees with results from Lengaigne et al., 2006 and Lengaigne et al.

, 2013). Another group found no relationship between dissolved methane in groundwater and proximity to gas wells, but did find topographic and geochemical relationships where methane

concentrations were higher in valleys as well as in groundwater dominated by sodium chloride or sodium bicarbonate (Molofsky et al., 2013). In northeastern Pennsylvania, a multivariate regression of methane patterns using landscape and hydrogeologic factors found gas well proximity, groundwater residence time, and well depth relative to certain geologic strata to be most dominant, though only 28% of variation in methane was explained with the regression (Pelepko, 2013). A fourth study found no correlation between groundwater methane and proximity to gas wells, but did not examine other landscape characteristics that might be driving RAD001 observed values (Boyer et al., 2012). The objectives

of this study were to obtain groundwater quality data from domestic wells in central New York in order to (1) investigate baseline distributions of dissolved methane and other water quality parameters, including major cations and anions, and (2) to analyze dissolved methane patterns using a variety of statistical techniques in order find more to understand environmental drivers of the observed patterns. The chosen study area was Chenango County, which is a 2315 km2 (894 mi2) region (US Census, 2012) located in the glaciated Appalachian Plateau portion of central New York State (McPherson, 1993). The county is dominated by agricultural and forested land (Crandall, 1985). Surficial geology is characterized by unconsolidated glacial till that mantles the bedrock uplands except on hilltops, north-facing hillslopes, and truncated spur hillsides where the till is absent and bedrock crops O-methylated flavonoid out at the land surface; with

major valleys containing thicker sediments comprised of alluvium and glacialfluvial outwash and glaciolacustrine fine sand, silt, and clay (Cadwell, 1991, Hetcher et al., 2003 and Hetcher-Aguila and Miller, 2005). Bedrock in the county is dominated by Upper and Middle Devonian shale with sandstone, siltstone, limestone and black shale also present in some formations (Fig. 1). Underlying stratigraphy is shown in Fig. 1b. As of April 2012, there were 93 natural gas wells in the county, with 33 of these wells considered active. Drilling density, considering all existing wells, varies across the county, from 0 in several townships to 0.48 wells km−2 in Smyrna Township (Fig. 2). These wells primarily produce from the Oriskany and Herkimer Sandstones and Oneida Conglomerate (NYSDEC, 2012). However, advances in drilling technologies have resulted in interest by natural gas companies to produce natural gas from organic-rich shales.

It should be noted that such wind conditions are of a click here purely hypothetical character, as the probability of their occurrence is extremely low. Momentum, heat and water air-sea fluxes in the last four experiments were calculated assuming that the atmospheric fields – wind, air temperature, relative humidity and cloudiness – are stationary and horizontally homogeneous (Table 2). The atmospheric parameters used in the flux calculations were determined according to the Climate Atlas

of Croatia (Zaninović et al. 2008). Sea density profiles were extracted from the 3D numerical model results at the positions of the submarine outfalls analysed with a 12 h time increment (Figure 1). These vertical profiles were used in the implemented near-field numerical model for calculating effluent mixing in the vicinity of the submarine outfalls. The near-field model supplies relevant data on the maximum vertical positions of the effluent plume above the sea bottom for successive density vertical distributions using a 12 h increment over a period of 48 h. Since the density profiles

obtained from the measurements in March were vertically well mixed, the effluent plume could reach the sea surface even without wind assistance; numerical analysis of the mixing process in the near-field was not carried out for March. Verification of the 3D numerical model results for the

period from 3 to 7 September 1976 was carried Crenolanib manufacturer out using the initial and boundary conditions explained in section 2. Figure 5 shows snapshots of the current velocity fields at 1, 5, 10, 20 and 30 m depth at the time coinciding with the registered wind speed maxima (21 m s−1 – Figure 2) from the NE. Downwind currents are found in the upper layer extending down to 20 m depth, while compensating north-eastward and eastward flows are from 20 m depth to the bottom. Figure 6 shows a comparison of the measured and modelled T profiles at oceanographic stations 1–5 (Figure 1). The differences in the middle and bottom layers at measurement site 4 are small and most likely caused by the presence of the local bottom freshwater springs typical of the area but not included in the model simulation. At station 5 the differences are Olopatadine the most pronounced but still small, probably due to errors in the initial vertical T profile used in the vicinity of station 5. Figures 7 and 8 show the hourly averaged current velocity fields at 1, 10 and 40 m depth during the constant wind forcing from the NE with speeds of 7.5 and 10 m s−1, 24 and 48 h after the wind forcing onset. The former results refer to the period from late June until early July. The current field structure with outgoing flow in the surface layer and compensating currents below are similar in all the experiments.

Control cells or cells incubated with DMA for 72 h showed similar amounts of cells in sub-G1 that was equal to or below 10%. In order to gain insight into the type of cell death induced by PCP, we investigated cleavage of PARP as a measure of early-stage apoptosis and the cleavage of the major members of the extrinsic and intrinsic pathways ALK inhibitor clinical trial of caspase activation. Panc-1 and MIA PaCa-2 cells were incubated with

C11 and PCP at 100 μM concentration for 48 h, respectively. As shown in Fig. 3b, cell death activation appears to occur through the extrinsic caspase pathways as Western blot analysis revealed cleavage of caspase-8, -3 and PARP as compared to untreated cells. In the case of caspase-9, we observed a decreased intensity of full-length caspase-9 band in MIA PaCa-2 cells treated with PCP with respect Selleckchem MLN0128 to control cells indicating activation of the intrinsic apoptotic pathway. However, in the case of Panc-1 cells, there was no significant difference in the caspase-9 band intensity between control and PCP-treated

cells suggesting activation of the sole extrinsic apoptotic pathway. Cathepsins are a family of lysosomal proteases stored in lysosomes as inactive precursors known for their ability to initiate apoptotic cell death independent of caspases [21] and [22]. However, of the cysteine proteases, cathepsin B has been often implicated in the invasive and malignant progression of several types of tumours including pancreas, making this enzyme a relevant marker to cancer [23], [24] and [25]. Hence, we addressed the question whether cathepsin B is involved in the

cell death mechanisms of pancreatic cancer cells. As shown in Fig. 4, cells were incubated with 100 μM C11 and 100 μM PCP for 48 h, respectively. The activity of cathepsin B from whole Farnesyltransferase cell extracts was measured by a fluorescence-based assay. The assay revealed a decrease of more than 50% in enzyme activity in both cell types suggesting that PCP-mediated inhibition of cathepsin B activity contributes to induce cell death in the investigated cell lines. Treatment of cells with 150 μM temozolomide (TMZ) served as a positive control indicating activation of cathepsin B. A negative control was performed in parallel represented by cell incubation with CB inhibitor. Next, cells were analysed for the release of cytochrome c from isolated mitochondria. As shown in Fig. 5a, detection of cytochrome c content in MIA PaCa-2 cells revealed that treatment with C11 and PCP leads to a decreased protein band signal with respect to control experiment, suggesting release of cytochrome c into the cytosol and, hence, caspase-mediated activation of apoptotic cell death. 100 μM PCP was the most effective concentration. However, a clear decrease of cytochrome c content was not observed in Panc-1 cells as compared to control experiment represented by cells incubated with DMSO. A hallmark of apoptosis is the loss of mitochondrial membrane potential [ΔΨm, [26] and [27]].

In addition, zymographic analysis demonstrated that some of these strains were also able to release several molecules with the same proteolytic activity, such as gelatinase (data not shown). Environmental bacteria considered to display low virulence, however, such as Acinetobacter spp. encountered Obeticholic Acid clinical trial in the mucus of P. motoro, can also become a threat to the patient if delivered into the wound, due their ability to survive in damaged tissue and resist antibiotic treatments ( Sebeny et al., 2008 and Dallo and Weitao, 2010). For this reason, these bacteria are even more dangerous to immune-compromised people who cannot fully fight the infection

that can develop with serious consequences. In addition, severe secondary infection by environmental bacteria can also progress in immune-competent hosts, as demonstrated by Markov et al. (2007) in a clinical report that describes a case of necrotizing fasciitis ( Thompson et al., 1993) in an immune-competent http://www.selleckchem.com/products/Lapatinib-Ditosylate.html patient due to A. hydrophila acquired in brackish water. Necrotizing fasciitis due to V. alginolyticus and P. damsela have also been reported in immune-competent patients after marine stingray accidents, both organisms being rarely associated with human infections, and nearly always encountered in immune-compromised

hosts ( Barber and Swygert, 2000 and Ho et al., 1998). Other bacterial species such as C. freundii, which in this work was encountered both in P. motoro mucus and in environmental water, has also been isolated from a wound acquired during a stingray accident ( Fenner et al., 1989). In addition to bacterial infections, invasive fusariosis due to Fuscarium solani is also associated with injury acquired in a stingray accident ( Hiemenz et al., 1990). The clinical cases previously described highlight the importance check details of both bacterial and fungal wound-infections in stingray accidents. It is also important to take into consideration the fact that most environmental bacteria are multi-drug resistant (Grobusch et al., 2001, Rennie et al., 2003, Valencia et al., 2004, Horii et al., 2005, Flattau et al., 2008 and Shak et al.,

2011). A. hydrophila resistant to amikacin, tobramycin and multiple ceplalosporins has been isolated from a polymicrobial infection acquired during a fall into freshwater ( Shak et al., 2011). Also, P. damsela with intermediate resistance to amikacin has been isolated from a wound acquired in a stingray accident ( Barber and Swygert, 2000). In our work, none of the strains isolated was resistant to this antibiotic, but 68% of all Gram-negative isolates were highly resistant to other types of beta-lactam antibiotics, indicating that they were able to produce beta-lactamases, which in case of mixed infections can be released into the wound and protect susceptible bacteria against this category of antibiotic ( Brook et al., 1983, Brook et al., 1984 and Brook, 2009).

1c). However, the loss of the mandible angle and the presence of wormian bones might have suggested a diagnosis of Pycnodysostosis (Fig. 1a bottom). He is alive at 5 years in reasonably good conditions. In all patients laboratory findings regarding the immune compartment were within a normal range, even though no extensive characterization was done. We performed exome sequencing in the 2 affected siblings of Family 1 and achieved in both patients a 69 × mean coverage over the 62 Mb targeted exome, with more than 94% of targeted regions covered. The overall transition to transversion rate VEGFR inhibitor (Ti/Tv) was 2.50 in line with what was expected for exome sequencing. The analysis identified

a total of 179143 variants which were filtered with dbSNP137 and 1000 Genome Obeticholic Acid in vitro Project and according to the pattern of inheritance of the disease

and to the parental consanguinity (Table 1). Among the homozygous variants, we found a mutation in exon 3 of the CTSK gene (g.2128C > T) which could be considered responsible for the disease in Patients 1A and 1B ( Table 2); of note, the same mutation, leading to an amino acid substitution at codon 46 (p.Arg46Trp), was already known to cause Pycnodysostosis [16]. The nucleotide change was confirmed by Sanger sequencing in the homozygous state in the patients and in the heterozygous state in their parents ( Supplementary Fig. 1, which also shows the mutations found in the other patients). This finding prompted us to sequence the CTSK gene in other 25 patients sent us with a clinical diagnosis of autosomal recessive osteopetrosis (ARO) but in whom we could not identify a molecular defect in the known ARO genes [3]. Among these patients we identified 4 individuals bearing mutations in the CTSK gene. In particular, Patient 2 was a compound heterozygote for the nucleotide change above described and a deletion of 3 nucleotides in exon 4 (g.2343_2345del), leading Sitaxentan to the deletion of a single residue (p.Lys89del). Her father

was heterozygous for the missense mutation, while maternal DNA was not available as the patient’s mother deceased several years earlier. Patient 3 was homozygous for a transversion in exon 4 (g.2340A > C) leading to an amino acid substitution at codon 88 (p.Gln88Pro); this nucleotide change was confirmed in her parents in the heterozygous state. Patient 4 was compound heterozygous for a nucleotide change in exon 3 (g.2131C > A), causing an amino acid substitution at codon 47 (p.Arg47Ser), and a deletion of 2 nucleotides in exon 6 (g.8746_8747del), causing a frameshift and a premature protein termination (p.Ser246CysfsX4). Patient 5 was homozygous for the same nucleotide change found in patients 1A, 1B and 2 (g.2128C > T); his parents carried this mutation in the heterozygous state. Apart from p.Arg46Trp, the other changes are herein described for the first time. The 3 missense mutations (p.Arg46Trp, p.Arg47Ser and p.Gln88Pro) and the single amino acid deletion (p.
