RCV003748089 | SCV004482243 | uncertain significance | Autoimmune lymphoproliferative syndrome due to CTLA4 haploinsufficiency | 2023-10-16 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 55 of the CTLA4 protein (p.Ser55Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CTLA4-related conditions. 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 asparagine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
