Genes affected
CD3G (HGNC:1675): (CD3 gamma subunit of T-cell receptor complex) The protein encoded by this gene is the CD3-gamma polypeptide, which together with CD3-epsilon, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. Defects in this gene are associated with T cell immunodeficiency.

Combined immunodeficiency due to CD3gamma deficiency Uncertain:1
Dec 22, 2018
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method: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: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". 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. This variant has not been reported in the literature in individuals with CD3G-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with valine at codon 14 of the CD3G protein (p.Ile14Val). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and valine. -

CD3G-related disorder Uncertain:1
Feb 13, 2023
PreventionGenetics, part of Exact Sciences
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The CD3G c.40A>G variant is predicted to result in the amino acid substitution p.Ile14Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.015% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-118215178-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
