Application

Application Comment Organism
medicine to establish a diagnosis of recessive congenital methaemoglobinaemia (RCM), it is important to demonstrate enzyme deficiency of cb5r and this is usually done using a spectrophotometric method,. RCM type I patients manifest a deficiency of cb5r in erythrocytes only whereas type II patients harbour the deficiency in both erythrocytes and leucocytes Homo sapiens

2 ferricytochrome b5 + NADH Homo sapiens recessive congenital methaemoglobinaemia, is caused by NADH-cytochrome b5 reductase deficiency. Two distinct clinical forms, types I and II, are recognized, both characterized by cyanosis from birth. In type II, the cyanosis is accompanied by neurological impairment and reduced life expectancy 2 ferrocytochrome b5 + NAD+ + H+
