Labcorp Genetics (formerly Invitae), Labcorp RCV001248048 SCV001421509 uncertain significance Immunodeficiency 35 2022-08-09 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 386 of the TYK2 protein (p.Val386Met). This variant is present in population databases (rs55956017, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with TYK2-related conditions. ClinVar contains an entry for this variant (Variation ID: 972099). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.
