Labcorp Genetics (formerly Invitae), Labcorp RCV001982399 SCV002225196 uncertain significance Dyskeratosis congenita, autosomal dominant 6 2023-07-17 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 507 of the ACD protein (p.Pro507Arg). This variant is present in population databases (rs149418249, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with ACD-related conditions. ClinVar contains an entry for this variant (Variation ID: 1444406). 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 ACD protein function. 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.
