Background Information

CYP26B1(Cytochrome P450 26B1) is involved in the metabolism of retinoic acid (RA), rendering this classical morphogen inactive through oxidation.It has 3 isoforms produced by alternative splicing.Cyp26b1 deficiency induces pronounced apoptosis in the developing limb and delayed chondrocyte maturation(PMID:15030763).Defects in CYP26B1 are the cause of radiohumeral fusions with other skeletal and craniofacial anomalies (RHFCA).
