RCV002032872 | SCV002120411 | uncertain significance | X-linked lymphoproliferative disease due to XIAP deficiency | 2021-05-17 | criteria provided, single submitter | clinical testing | 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 alanine with valine at codon 68 of the XIAP protein (p.Ala68Val). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and valine. 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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 valine 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. |
