Genes affected

CYP39A1 (HGNC:17449): (cytochrome P450 family 39 subfamily A member 1) This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This endoplasmic reticulum protein is involved in the conversion of cholesterol to bile acids. Its substrates include the oxysterols 25-hydroxycholesterol, 27-hydroxycholesterol and 24-hydroxycholesterol. Alternate splicing results in multiple transcript variants.

The c.1360G>A (p.V454I) alteration is located in exon 12 (coding exon 12) of the CYP39A1 gene. This alteration results from a G to A substitution at nucleotide position 1360, causing the valine (V) at amino acid position 454 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
