Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 138 of the CCDC103 protein (p.Asp138Ala). This variant is present in population databases (rs372407548, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with CCDC103-related conditions. ClinVar contains an entry for this variant (Variation ID: 455028). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
