Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_000732.6(CD3D):c.505C>T(p.Arg169Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000018 in 1,613,816 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign 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. R169Q) has been classified as Uncertain significance.

Inborn genetic diseases Uncertain:1
The c.505C>T (p.R169W) alteration is located in exon 5 (coding exon 5) of the CD3D gene. This alteration results from a C to T substitution at nucleotide position 505, causing the arginine (R) at amino acid position 169 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Immunodeficiency 19 Uncertain:1
This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 169 of the CD3D protein (p.Arg169Trp). This variant is present in population databases (rs367800432, 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: 962292). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
