Labcorp Genetics (formerly Invitae), Labcorp RCV001305582 SCV001494921 uncertain significance Idiopathic generalized epilepsy; Hyperaldosteronism, familial, type IV 2020-06-08 criteria provided, single submitter clinical testing This sequence change replaces isoleucine with valine at codon 1077 of the CACNA1H protein (p.Ile1077Val). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and valine. This variant is not present in population databases (ExAC no frequency). 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with CACNA1H-related conditions.
