Labcorp Genetics (formerly Invitae), Labcorp RCV002629057 SCV003517010 uncertain significance Infantile-onset X-linked spinal muscular atrophy 2022-01-21 criteria provided, single submitter clinical testing 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: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with UBA1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.008%), including at least one homozygous and/or hemizygous individual. This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 699 of the UBA1 protein (p.Arg699Gln).
