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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 2415533). This variant has not been reported in the literature in individuals affected with POC5-related conditions. This variant is present in population databases (rs550940695, gnomAD 0.09%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 539 of the POC5 protein (p.Tyr539Cys). -
