Genes affected

CDH3 (HGNC:1762): (cadherin 3) This gene encodes a classical cadherin of the cadherin superfamily. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature glycoprotein. This calcium-dependent cell-cell adhesion protein is comprised of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. This gene is located in a gene cluster in a region on the long arm of chromosome 16 that is involved in loss of heterozygosity events in breast and prostate cancer. In addition, aberrant expression of this protein is observed in cervical adenocarcinomas. Mutations in this gene are associated with hypotrichosis with juvenile macular dystrophy and ectodermal dysplasia, ectrodactyly, and macular dystrophy syndrome (EEMS). [provided by RefSeq, Nov 2015]

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 503 of the CDH3 protein (p.Arg503His). This variant is present in population databases (rs121434542, gnomAD 0.003%). This missense change has been observed in individuals with autosomal recessive hypotrichosis with juvenile macular dystrophy (PMID: 12445216, 14708629, 27386845, 30710256). It is commonly reported in individuals of Arab Israeli ancestry (PMID: 14708629). ClinVar contains an entry for this variant (Variation ID: 17639). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt CDH3 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic.
