Variant summary
Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000732.6(CD3D):c.202C>T(p.Arg68*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000533 in 1,613,980 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. R68R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

This sequence change creates a premature translational stop signal (p.Arg68*) in the CD3D gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CD3D are known to be pathogenic (PMID: 14602880, 15546002). This variant is present in population databases (rs111033580, gnomAD 0.004%). This premature translational stop signal has been observed in individuals with severe combined immunodeficiency (SCID) (PMID: 14602880, 15546002, 21883749, 22039266, 27807805). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 12747). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
