First report of X-linked hypohidrotic ectodermal dysplasia with a hemizygous c.1142G > C in the EDA gene: variant of uncertain significance or new pa…

AbstractBackgroundHypohidrotic Ectodermal Dysplasia (HED) is a genetic disorder which affects structures of ectodermal origin. X-linked hypohidrotic ectodermal dysplasia (XLHED) is the most common form of disease. XLHED is characterized by hypotrichosis, hypohydrosis and hypodontia. The cardinal features of classic HED become obvious during childhood.Identification of a hemizygous EDA pathogenic variant in an affected male confirms the diagnosis.Case presentationWe report on a male newborn with the main clinical characteristics of the X-linked HED including hypotrichosis, hypodontia and hypohidrosis. Gene panel sequencing identified a new hemizygous missense variant of uncertain significanc…
A new mutation in EDA gene in X-linked hypohidrotic ectodermal dysplasia associated with keratoconus
2012
Hypohidrotic ectodermal dysplasia (HED) was first described in 1848 by Thurnam. HED belongs to ectodermal dysplasias (EDs), which are developmental impairments of ectodermal-derived tissues. X-linked hypohidrotic ectodermal dysplasia (XLHED) is the most common form of the EDs and consists in abnormal development of teeth, hair, and eccrine sweat glands. XLHED is determined by mutations in the ED1 gene, which is responsible for the coding of ectodysplasin-A(EDA-A), a protein that regulates ectodermal appendage formation. In the present study we found both in our proband and in the mother the same missense mutation in exon 9 (c.957 CA), which resulted in an aminoacid change at position 319 (S…
