Description

This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 136 of the CLRN1 protein (p.Gly136Glu). This variant is present in population databases (rs779258184, gnomAD 0.2%). This missense change has been observed in individual(s) with clinical features of CLRN1-related conditions (PMID: 31960602). ClinVar contains an entry for this variant (Variation ID: 556027). 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 disruptive. 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.
