Variant summary
Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1PM2PP3_Strong
The NM_005214.5(CTLA4):c.374G>A(p.Gly125Glu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G125R) has been classified as Uncertain significance.

Genes affected
CTLA4 (HGNC:2505): (cytotoxic T-lymphocyte associated protein 4) This gene is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.

Autoimmune lymphoproliferative syndrome due to CTLA4 haploinsufficiency Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 02, 2021 | ClinVar contains an entry for this variant (Variation ID: 475276). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. This variant has not been reported in the literature in individuals affected with CTLA4-related conditions. This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 125 of the CTLA4 protein (p.Gly125Glu). This variant is not present in population databases (gnomAD no frequency). - |
