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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.00992161).

BP6

Variant 2-97734655-T-C is Benign according to our data. Variant chr2-97734655-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 337634.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000624 (95/152350) while in subpopulation NFE AF = 0.000706 (48/68022). AF 95% confidence interval is 0.000547. There are 0 homozygotes in GnomAd4. There are 43 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
