Description

This sequence change replaces tyrosine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 12 of the CASQ2 protein (p.Tyr12Asn). This variant is present in population databases (rs752330104, gnomAD 0.006%). This missense change has been observed in individual(s) with catecholaminergic polymorphic ventricular tachycardia (Invitae). ClinVar contains an entry for this variant (Variation ID: 190750). 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 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.
