EBP (human)

Overview
EBP Catalyzes the conversion of Delta(8)-sterols to their corresponding Delta(7)-isomers. Defects in EBP are the cause of chondrodysplasia punctata X-linked dominant type 2 (CDPX2); also known as Conradi-Hunermann-Happle syndrome. CDP is a clinically and genetically heterogeneous disorder characterized by punctiform calcification of the bones. The key clinical features of CDPX2 are chondrodysplasia punctata, linear ichthyosis, cataracts and short stature. CDPX2 is a rare disorder of defective cholesterol biosynthesis, biochemically characterized by an increased amount of 8-dehydrocholesterol and cholest-8(9)-en-3-beta-ol in the plasma and tissues. Belongs to the EBP family. Note: This description may include information from UniProtKB.
