Labcorp Genetics (formerly Invitae), Labcorp RCV001935057 SCV002172829 uncertain significance Idiopathic generalized epilepsy; Hyperaldosteronism, familial, type IV 2022-12-05 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 646 of the CACNA1H protein (p.His646Gln). 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: 1401276). This variant has not been reported in the literature in individuals affected with CACNA1H-related conditions.
Fulgent Genetics, Fulgent Genetics RCV002490203 SCV002793680 uncertain significance Epilepsy, childhood absence, susceptibility to, 6; Hyperaldosteronism, familial, type IV 2021-07-17 criteria provided, single submitter clinical testing
