Invitae	RCV000631698	SCV000752782	uncertain significance	Long QT syndrome	2023-12-29	criteria provided, single submitter	clinical testing	This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1865 of the CACNA1C protein (p.Glu1865Lys). 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 missense change has been observed in individual(s) with clinical features of CACNA1C-related conditions (PMID: 32145446). This variant is also known as c.5617G>A (p.E1873K). ClinVar contains an entry for this variant (Variation ID: 191566). 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 with a negative predictive value of 95%. 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.
