Genes affected

IL36RN (HGNC:15561): (interleukin 36 receptor antagonist) The protein encoded by this gene is a member of the interleukin 1 cytokine family. This cytokine was shown to specifically inhibit the activation of NF-kappaB induced by interleukin 1 family, member 6 (IL1F6). This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. Two alternatively spliced transcript variants encoding the same protein have been reported.

This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 77 of the IL36RN protein (p.Thr77Ile). This variant is present in population databases (rs372880215, gnomAD 0.01%). This missense change has been observed in individual(s) with psoriasis (PMID: 23792462). ClinVar contains an entry for this variant (Variation ID: 529885). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The isoleucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
