Pathway Description
Desmosterolosis
Homo sapiens
Disease Pathway
Desmosterolosis is caused by a mutation in the DHCR24 gene, which codes for the enzyme 24-dehydrocholesterol reductase, which catalyzes the reduction of the delta-24 double bond of sterol intermediates. A defect in 24-dehydrocholesterol reductase causes accumulation of desmosterol in plasma. Symptoms include cleft palate, clubfoot, dysmorphism, mental and motor retardation, and speech development.
