Genes affected

RIPK4 (HGNC:496): (receptor interacting serine/threonine kinase 4) The protein encoded by this gene is a serine/threonine protein kinase that interacts with protein kinase C-delta. The encoded protein can also activate NFkappaB and is required for keratinocyte differentiation. This kinase undergoes autophosphorylation. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 21-41739813-C-A is Benign according to our data. Variant chr21-41739813-C-A is described in ClinVar as Benign. ClinVar VariationId is 895208.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00483 (736/152356) while in subpopulation NFE AF = 0.0077 (524/68032). AF 95% confidence interval is 0.00716. There are 3 homozygotes in GnomAd4. There are 360 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 3 AR gene
