Description

This sequence change replaces phenylalanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 14 of the CRYAB protein (p.Phe14Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CRYAB-related conditions. ClinVar contains an entry for this variant (Variation ID: 1390439). 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. 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.
