RCV001343806 | SCV001537815 | uncertain significance | X-linked lymphoproliferative disease due to XIAP deficiency | 2020-05-21 | 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: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glutamine 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 XIAP-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with glutamine at codon 238 of the XIAP protein (p.Arg238Gln). The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and glutamine. |
