Illumina Laboratory Services, Illumina RCV001117131 SCV001275294 uncertain significance MHC class II deficiency 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Labcorp Genetics (formerly Invitae), Labcorp RCV001117131 SCV001421838 uncertain significance MHC class II deficiency 2022-10-24 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1018 of the CIITA protein (p.Glu1018Lys). This variant is present in population databases (rs747047617, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with CIITA-related conditions. ClinVar contains an entry for this variant (Variation ID: 885507). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
