Genes affected

TNIK (HGNC:30765): (TRAF2 and NCK interacting kinase) Wnt signaling plays important roles in carcinogenesis and embryonic development. The protein encoded by this gene is a serine/threonine kinase that functions as an activator of the Wnt signaling pathway. Mutations in this gene are associated with an autosomal recessive form of cognitive disability. Alternative splicing results in multiple transcript variants encoding different isoforms.

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP6: Variant 3-171228239-T-C is Benign according to our data. Variant chr3-171228239-T-C is described in ClinVar as Likely_benign. ClinVar VariationId is 446077.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00643 (978/152214) while in subpopulation AFR AF = 0.0221 (917/41536). AF 95% confidence interval is 0.0209. There are 10 homozygotes in GnomAd4. There are 457 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 10 AR,Unknown gene
