Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_001079.4(ZAP70):c.1415G>A(p.Arg472Gln) variant causes a missense change. The variant allele was found at a frequency of 0.0000248 in 1,613,962 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/22 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. R472W) has been classified as Uncertain significance.

ZAP70-Related Severe Combined Immunodeficiency Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 472 of the ZAP70 protein (p.Arg472Gln). This variant is present in population databases (rs758807149, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with ZAP70-related conditions. ClinVar contains an entry for this variant (Variation ID: 538568). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. -
