Genes affected

EDA (HGNC:3157): (ectodysplasin A) The protein encoded by this gene is a type II membrane protein that can be cleaved by furin to produce a secreted form. The encoded protein, which belongs to the tumor necrosis factor family, acts as a homotrimer and may be involved in cell-cell signaling during the development of ectodermal organs. Defects in this gene are a cause of ectodermal dysplasia, anhidrotic, which is also known as X-linked hypohidrotic ectodermal dysplasia. Several transcript variants encoding many different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects EDA function (PMID: 19623212). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt EDA protein function. ClinVar contains an entry for this variant (Variation ID: 11048). This missense change has been observed in individual(s) with isolated tooth agenesis and hypohidrotic ectodermal dysplasia (PMID: 18545687, 18657636, 27657131). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 338 of the EDA protein (p.Thr338Met). -
