DHCR24
The enzyme 3-beta-hydroxysterol delta-24-reductase (DHCR24), a member of the flavin adenine dinucleotide (FAD)-dependent oxidoreductases, catalyzes the reduction of the delta-24 double bond of sterol intermediates during cholesterol biosynthesis.
Pathology
Desmosterolosis is caused by mutation in the DHCR24 gene (MIM.606418).
Desmosterolosis is a rare autosomal recessive disorder characterized by multiple congenital anomalies and elevated levels of the cholesterol precursor desmosterol in plasma, tissue, and cultured cells.
