Genes affected

RIPK2 (HGNC:10020): (receptor interacting serine/threonine kinase 2) This gene encodes a member of the receptor-interacting protein (RIP) family of serine/threonine protein kinases. The encoded protein contains a C-terminal caspase activation and recruitment domain (CARD), and is a component of signaling complexes in both the innate and adaptive immune pathways. It is a potent activator of NF-kappaB and inducer of apoptosis in response to various stimuli. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.949

The c.815G>A (p.G272E) alteration is located in exon 6 (coding exon 6) of the RIPK2 gene. This alteration results from a G to A substitution at nucleotide position 815, causing the glycine (G) at amino acid position 272 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
