Labcorp Genetics (formerly Invitae), Labcorp RCV001317349 SCV001508007 uncertain significance Idiopathic generalized epilepsy; Hyperaldosteronism, familial, type IV 2021-02-01 criteria provided, single submitter clinical testing This sequence change replaces valine with isoleucine at codon 2101 of the CACNA1H protein (p.Val2101Ile). The valine residue is highly conserved and there is a small physicochemical difference between valine and isoleucine. 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with CACNA1H-related conditions. This variant is not present in population databases (ExAC no frequency).
