GeneDx RCV000170793 SCV000223348 uncertain significance not provided 2014-03-16 criteria provided, single submitter clinical testing p.Pro861Ser (CCA>TCA): c.2581 C>T in exon 19 of the CACNA1C gene (NM_000719.6). The Pro861Ser variant in the CACNA1C gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Pro861Ser results in a non-conservative amino acid substitution of a non-polar Proline residue with a neutral, polar Serine residue at a position that is conserved across species. In silico analysis predicts Pro861Ser is possibly damaging to the protein structure/function. The NHLBI Exome Variant Server reports Pro861Ser was not observed in approximately 6,000 samples from individuals of European and African American backgrounds, indicating it is not a common benign variant in these populations. Nevertheless, mutations in nearby residues have not been reported in association with LQTS, indicating this region of the protein may be tolerant of change. With the clinical and molecular information available at this time, we cannot definitively determine if Pro861Ser is a disease-causing mutation or a rare benign variant. The variant is found in LQT panel(s).
