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: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine 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 RAG1-related conditions. This variant is present in population databases (rs745600099, ExAC 0.003%). This sequence change replaces phenylalanine with leucine at codon 5 of the RAG1 protein (p.Phe5Leu). The phenylalanine residue is weakly conserved and there is a small physicochemical difference between phenylalanine and leucine. |
