Genes affected

IL23R (HGNC:19100): (interleukin 23 receptor) The protein encoded by this gene is a subunit of the receptor for IL23A/IL23. This protein pairs with the receptor molecule IL12RB1/IL12Rbeta1, and both are required for IL23A signaling. This protein associates constitutively with Janus kinase 2 (JAK2), and also binds to transcription activator STAT3 in a ligand-dependent manner. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.69).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.758 is higher than 0.05.
