Labcorp Genetics (formerly Invitae), Labcorp RCV002527379 SCV002943764 uncertain significance T-B+ severe combined immunodeficiency due to JAK3 deficiency 2022-06-12 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 431 of the JAK3 protein (p.Arg431Trp). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with JAK3-related conditions. ClinVar contains an entry for this variant (Variation ID: 440938). 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.
