Description

The p.R549C variant (also known as c.1645C>T), located in coding exon 6 of the KCND3 gene, results from a C to T substitution at nucleotide position 1645. The arginine at codon 549 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
