Ambry Genetics RCV002416854 SCV002677983 uncertain significance Inborn genetic diseases 2024-02-10 criteria provided, single submitter clinical testing The p.Q265R variant (also known as c.794A>G), located in coding exon 7 of the ACD gene, results from an A to G substitution at nucleotide position 794. The glutamine at codon 265 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV003754958 SCV004553863 uncertain significance Dyskeratosis congenita, autosomal dominant 6 2023-02-11 criteria provided, single submitter clinical testing This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 265 of the ACD protein (p.Gln265Arg). This variant is present in population databases (rs754351563, gnomAD 0.006%). 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: 1761350). 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 not 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.
