Ambry Genetics RCV002396507 SCV002699877 uncertain significance Inborn genetic diseases 2022-07-19 criteria provided, single submitter clinical testing The p.L344P variant (also known as c.1031T>C), located in coding exon 9 of the ACD gene, results from a T to C substitution at nucleotide position 1031. The leucine at codon 344 is replaced by proline, an amino acid with 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 RCV003095070 SCV003523237 uncertain significance Dyskeratosis congenita, autosomal dominant 6 2022-04-03 criteria provided, single submitter clinical testing This variant is present in population databases (rs573094162, gnomAD 0.003%). 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. 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with ACD-related conditions. This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 344 of the ACD protein (p.Leu344Pro).
