Description

This sequence change replaces asparagine with serine at codon 69 of the IL1RN protein (p.Asn69Ser). The asparagine residue is weakly conserved and there is a small physicochemical difference between asparagine and serine. This variant is present in population databases (rs761355602, ExAC 0.004%). This variant has not been reported in the literature in individuals affected with IL1RN-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
