Ectodermal dysplasia with immune deficiency (EDI) is caused by alterations in NEMO (nuclear factor [NF]-kappaB essential modulator). Most genetic mutations are located in exon 10 and affect the C-terminal zinc finger domain. However, the biochemical mechanism by which they cause immune dysfunction
X-linked hypohidrotic ectodermal dysplasia (EDA) is characterized by the hypoplasia or absence of hair, teeth and sweat glands. In this study, the authors investigated the ED1 gene in a Japanese family with X-linked hypohidrotic ectodermal dysplasia. The only affected male fulfils the diagnostic
Ectrodactyly-ectodermal dysplasia-clefting syndrome is an uncommon disorder that includes a clinical spectrum of limb, facial, ocular, internal ear, and urogenital malformations. The disease is caused by heterozygous mutations in the 3q27-29 located p63 gene. In this paper we describe a 17-year-old
BACKGROUND
Ectodermal dysplasias are developmental disorders affecting tissues of ectodermal origin. To date, four different types of ectodermal dysplasia involving only hair and nails have been described. In an effort to understand the molecular bases of this form of ectodermal dysplasia, large
Several ectodermal dysplasia syndromes have been shown to result from mutations in the gene that encodes the transcription factor p63. We describe an 11-year-old boy, with clinically normal parents, who had a developmental disorder that resembled EEC (ectrodactyly ectodermal dysplasia-clefting)
BACKGROUND
Germline mis-sense mutations in the DNA-binding domain of the p63 gene have recently been established as the molecular basis for the autosomal dominant EEC (Ectrodactyly, Ectodermal dysplasia, Clefting) syndrome.
OBJECTIVE
To examine genomic DNA from a 36-year-old woman, her 58-year-old
BACKGROUND
Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder characterized by defective development of teeth, hair, nails and eccrine sweat glands. Both autosomal dominant and autosomal recessive forms of HED have previously been linked to mutations in the ectodysplasin 1 anhidrotic
BACKGROUND
Aplasia cutis congenita (ACC) has been associated with all clinical forms of inherited epidermolysis bullosa (EB), including dominant and recessive dystrophic EB (DDEB and RDEB). To date, only a few patients with DEB specifically combined with ACC have been described and genotyped and
The ADULT syndrome (Acro-Dermato-Ungual-Lacrimal-Tooth, OMIM 103285) is a rare ectodermal dysplasia associated with limb malformations and caused by heterozygous mutations in p63. ADULT syndrome has clinical overlap with other p63 mutation syndromes, such as EEC (OMIM 604292), LMS (OMIM 603543), AEC
Various combinations of limb anomalies, ectodermal dysplasias and orofacial clefts characterize heterozygous mutations in the transcription factor gene p63. The causative gene is crucial during embryonic ontogenesis, mostly in the development of limbs and other ectodermal derived tissues. The
Aplasia cutis congenita (ACC) manifests with localized skin defects at birth of unknown cause, mostly affecting the scalp vertex. Here, genome-wide linkage analysis and exome sequencing was used to identify the causative mutation in autosomal dominant ACC. A heterozygous Arg-to-His missense mutation
X-linked hypohidrotic ectodermal dysplasia (XLHED), which is characterized by hypodontia, hypotrichosis, and hypohidrosis, is caused by mutations in ED1, the gene encoding ectodysplasin-A (EDA). This protein belongs to the tumor necrosis factor ligand superfamily. We analyzed ED1 in two Japanese
Mutations in the EDA gene are responsible for X-linked hypohidrotic ectodermal dysplasia, the most common form of ectodermal dysplasia. Males show a severe form of this disease, while females often manifest mild to moderate symptoms. We identified a missense mutation (c.463C>T) in the EDA gene in a
OBJECTIVE
To analyze GJB6 gene mutations in a Chinese family with hidrotic ectodermal dysplasia and to provide first-trimester prenatal diagnosis for a fetus.
METHODS
Mutation scanning was carried out with PCR and bilateral direct sequencing in 2 affected and 6 unaffected individuals from the
