Labcorp Genetics (formerly Invitae), Labcorp RCV001940052 SCV002180711 uncertain significance Immunodeficiency 104 2021-08-28 criteria provided, single submitter clinical testing This sequence change replaces leucine with phenylalanine at codon 248 of the IL7R protein (p.Leu248Phe). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and phenylalanine. This variant is present in population databases (rs200086692, ExAC 0.02%). This variant has not been reported in the literature in individuals affected with IL7R-related conditions. 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"). 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.
