Labcorp Genetics (formerly Invitae), Labcorp RCV001313573 SCV001504074 uncertain significance Immunodeficiency 104 2020-02-19 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25". The alanine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with IL7R-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with alanine at codon 160 of the IL7R protein (p.Val160Ala). The valine residue is highly conserved and there is a small physicochemical difference between valine and alanine.
