Genes affected
CD3D (HGNC:1673): (CD3 delta subunit of T-cell receptor complex) The protein encoded by this gene is part of the T-cell receptor/CD3 complex (TCR/CD3 complex) and is involved in T-cell development and signal transduction. The encoded membrane protein represents the delta subunit of the CD3 complex, and along with four other CD3 subunits, binds either TCR alpha/beta or TCR gamma/delta to form the TCR/CD3 complex on the surface of T-cells. Defects in this gene are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (SCIDBNK). Two transcript variants encoding different isoforms have been found for this gene. Other variants may also exist, but the full-length natures of their transcripts has yet to be defined.

This sequence change creates a premature translational stop signal (p.Arg153*) in the CD3D gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 19 amino acid(s) of the CD3D protein. This variant is present in population databases (rs201994476, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with CD3D-related conditions. ClinVar contains an entry for this variant (Variation ID: 940758). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
