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.

The R261W variant in the IL10RA gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. This variant is observed in 43/10,152 alleles (0.4%) from individuals of Ashkenazi Jewish background, and 117/276,954 global alleles (0.04%), in large population cohorts (Lek et al., 2016). The R261W variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position where amino acids with similar properties to Arginine are tolerated across species. However, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. The R261W variant is reported as a variant of uncertain significance in ClinVar by different clinical laboratories, but additional evidence is not available (ClinVar SCV000297101.2, SCV000367434.2; Landrum et al., 2016). We also interpret R261W as a variant of uncertain significance.

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
