Genes affected

CD247 (HGNC:1677): (CD247 molecule) The protein encoded by this gene is T-cell receptor zeta, which together with T-cell receptor alpha/beta and gamma/delta heterodimers, and with CD3-gamma, -delta and -epsilon, forms the T-cell receptor-CD3 complex. The zeta chain plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. Low expression of the antigen results in impaired immune response. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 1-167431887-C-T is Benign according to our data. Variant chr1-167431887-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1217835.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0181 (2756/152328) while in subpopulation NFE AF= 0.0274 (1862/68014). AF 95% confidence interval is 0.0263. There are 31 homozygotes in gnomad4. There are 1320 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 31 AR gene
