Invitae RCV002531420 SCV003515017 pathogenic Ectodermal dysplasia 10A, hypohidrotic/hair/nail type, autosomal dominant; Autosomal recessive hypohidrotic ectodermal dysplasia syndrome 2022-06-28 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg89 amino acid residue in EDAR. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 18231121, 20236127, 20979233). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 EDAR protein function. ClinVar contains an entry for this variant (Variation ID: 562015). This missense change has been observed in individual(s) with clinical features of ectodermal dysplasia (Invitae). This variant is present in population databases (rs780424781, gnomAD 0.006%). This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 89 of the EDAR protein (p.Arg89Cys).
