Description

The p.R450H variant (also known as c.1349G>A), located in coding exon 7 of the DHCR7 gene, results from a G to A substitution at nucleotide position 1349. The arginine at codon 450 is replaced by histidine, 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 deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
