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.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Lys69*) in the CD3G gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CD3G are known to be pathogenic (PMID: 1635567, 17277165, 24910257). This variant is present in population databases (rs199676861, gnomAD 0.04%). This premature translational stop signal has been observed in individual(s) with clinical features of combined immunodeficiency (PMID: 17277165). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 100626). For these reasons, this variant has been classified as Pathogenic. -
