Labcorp Genetics (formerly Invitae), Labcorp RCV001915732 SCV002181380 uncertain significance not provided 2022-08-31 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 421 of the POLR3A protein (p.Ile421Thr). This variant is present in population databases (rs748120667, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with POLR3A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1406245). 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: "Possibly 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.
