BACKGROUND Generalized pustular psoriasis is a life-threatening disease of unknown cause. It is characterized by sudden, repeated episodes of high-grade fever, generalized rash, and disseminated pustules, with hyperleukocytosis and elevated serum levels of C-reactive protein, which may be associated with plaque-type psoriasis. METHODS We performed(More)
Hypohidrotic and anhidrotic ectodermal dysplasia (HED/EDA) is a rare genodermatosis characterized by abnormal development of sweat glands, teeth, and hair. Three disease-causing genes have been hitherto identified, namely, (1) EDA1 accounting for X-linked forms, (2) EDAR, and (3) EDARADD, causing both autosomal dominant and recessive forms. Recently, WNT10A(More)
Connectivity in the developing hippocampus displays a functional organization particularly effective in supporting network synchronization, as it includes superconnected hub neurons. We have previously shown that hub network function is supported by a subpopulation of GABA neurons. However, it is unclear whether hub cells are only transiently present or(More)
Mutations of the EPCAM gene have been recently identified in Congenital Tufting Enteropathy (CTE), a severe autosomal recessive gastrointestinal insufficiency of childhood requiring parenteral nutrition and occasionally intestinal transplantation. Studying seven multiplex consanguineous families from the Arabic peninsula (Kuwait and Qatar) we found that(More)
Autosomal-recessive inheritance accounts for nearly 25% of nonsyndromic mental retardation (MR), but the extreme heterogeneity of such conditions markedly hampers gene identification. Combining autozygosity mapping and RNA expression profiling in a consanguineous Tunisian family of three MR children with mild microcephaly and white-matter abnormalities(More)
BACKGROUND Hypohidrotic ectodermal dysplasia (HED) is characterized by abnormal development of the eccrine sweat glands, hair and teeth. The X-linked form of the disease, caused by mutations in the EDA gene, represents the majority of HED cases. Autosomal dominant and recessive forms occasionally occur and result from mutations in at least two other genes:(More)
