Labcorp Genetics (formerly Invitae), Labcorp RCV001919470 SCV002188235 uncertain significance Hyperkalemic periodic paralysis 2024-02-04 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Ser1813*) in the SCN4A gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 24 amino acid(s) of the SCN4A protein. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SCN4A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1422310). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
