Genes affected

IL10RA (HGNC:5964): (interleukin 10 receptor subunit alpha) The protein encoded by this gene is a receptor for interleukin 10. This protein is structurally related to interferon receptors. It has been shown to mediate the immunosuppressive signal of interleukin 10, and thus inhibits the synthesis of proinflammatory cytokines. This receptor is reported to promote survival of progenitor myeloid cells through the insulin receptor substrate-2/PI 3-kinase/AKT pathway. Activation of this receptor leads to tyrosine phosphorylation of JAK1 and TYK2 kinases. Two transcript variants, one protein-coding and the other not protein-coding, have been found for this gene.

Inflammatory bowel disease 28 Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jun 03, 2023	For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on IL10RA protein function. ClinVar contains an entry for this variant (Variation ID: 39430). This missense change has been observed in individual(s) with very-early onset inflammatory bowel disease (PMID: 21519361, 24001973; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs149491038, gnomAD 0.002%). This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 262 of the IL10RA protein (p.Arg262Cys). -
