Genes affected

ZAP70 (HGNC:12858): (zeta chain of T cell receptor associated protein kinase 70) This gene encodes an enzyme belonging to the protein tyrosine kinase family, and it plays a role in T-cell development and lymphocyte activation. This enzyme, which is phosphorylated on tyrosine residues upon T-cell antigen receptor (TCR) stimulation, functions in the initial step of TCR-mediated signal transduction in combination with the Src family kinases, Lck and Fyn. This enzyme is also essential for thymocyte development. Mutations in this gene cause selective T-cell defect, a severe combined immunodeficiency disease characterized by a selective absence of CD8-positive T-cells. Two transcript variants that encode different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Variant summary: ZAP70 c.1393C>T (p.Arg465Cys) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251260 control chromosomes (gnomAD). c.1393C>T has been reported in the literature in a homozygous individual affected with Severe Combined Immunodeficiency (Elder_2001). These data indicate that the variant may be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function and found that the variant is catalytically inactive, with <10% normal activity (Elder_2001). The following publication has been ascertained in the context of this evaluation (PMID: 11123350). ClinVar contains an entry for this variant (Variation ID: 38912). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
