Labcorp Genetics (formerly Invitae), Labcorp RCV001230097 SCV001402567 uncertain significance Idiopathic generalized epilepsy; Hyperaldosteronism, familial, type IV 2023-03-20 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CACNA1H protein function. ClinVar contains an entry for this variant (Variation ID: 957166). This variant has not been reported in the literature in individuals affected with CACNA1H-related conditions. This sequence change replaces arginine, which is basic and polar, with threonine, which is neutral and polar, at codon 603 of the CACNA1H protein (p.Arg603Thr).
