Description

The p.Q498K variant (also known as c.1492C>A), located in coding exon 13 of the CACNB2 gene, results from a C to A substitution at nucleotide position 1492. The glutamine at codon 498 is replaced by lysine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
