Genes affected

NCR3 (HGNC:19077): (natural cytotoxicity triggering receptor 3) The protein encoded by this gene is a natural cytotoxicity receptor (NCR) that may aid NK cells in the lysis of tumor cells. The encoded protein interacts with CD3-zeta (CD247), a T-cell receptor. A single nucleotide polymorphism in the 5' untranslated region of this gene has been associated with mild malaria suceptibility. Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, May 2010]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PP5: Variant 6-31592893-C-T is Pathogenic according to our data. Variant chr6-31592893-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 1803723.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87). . Strength limited to SUPPORTING due to the PP5.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0233 (3539/152184) while in subpopulation AMR AF= 0.039 (595/15262). AF 95% confidence interval is 0.0364. There are 75 homozygotes in gnomad4. There are 1577 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
• BS2: High Homozygotes in GnomAd4 at 75 AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
