Ambry Genetics RCV000618088 SCV000738128 uncertain significance Cardiovascular phenotype 2017-08-04 criteria provided, single submitter clinical testing The p.D1913N variant (also known as c.5737G>A), located in coding exon 45 of the CACNA1C gene, results from a G to A substitution at nucleotide position 5737. The aspartic acid at codon 1913 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV001370869 SCV001567413 uncertain significance Long QT syndrome 2023-10-12 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 1913 of the CACNA1C protein (p.Asp1913Asn). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with CACNA1C-related conditions. ClinVar contains an entry for this variant (Variation ID: 519491). 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 CACNA1C protein function. 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.
