Invitae RCV003803693 SCV004591432 uncertain significance Ectodermal dysplasia 11A, hypohidrotic/hair/tooth type, autosomal dominant; Ectodermal dysplasia 11B, hypohidrotic/hair/tooth type, autosomal recessive 2023-10-10 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 135 of the EDARADD protein (p.Thr135Met). This variant is present in population databases (rs769122607, gnomAD 0.002%). This missense change has been observed in individual(s) with clinical features of autosomal recessive ectodermal dysplasia (Invitae). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. This variant disrupts a region of the EDARADD protein in which other variant(s) (p.Glu142Lys) have been observed in individuals with EDARADD-related conditions (PMID: 11780064). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
