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]

ClinVar contains an entry for this variant (Variation ID: 2099163). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬† is likely to be tolerated. This variant has not been reported in the literature in individuals affected with IL23R-related conditions. This variant is present in population databases (rs769230441, gnomAD 0.01%). This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 10 of the IL23R protein (p.Ala10Thr). -
