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]

RIPK4 Gene-Disease associations (from GenCC):

• Bartsocas-Papas syndrome 1

  Inheritance: AR Classification: DEFINITIVE, SUPPORTIVE Submitted by: Orphanet, G2P
• ectodermal dysplasia syndrome

  Inheritance: AR Classification: STRONG Submitted by: Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.561 is higher than 0.05.
