Cytochrome b reductase deficiency
WebRecessively inherited NADH-cytochrome B5 reductase deficiency, when present in the homozygous or doubly heterozygous form, is manifested by two different clinical presentations, depending on the nature and cellular distribution of the mutant enzyme. The observations supporting a clinical and biochem … WebThe identification of the enzyme as the soluble form of cytochrome b 5 reductase was established by Hultquist and Passon (1971). It is now generally accepted that RCM is caused by a deficiency of the enzyme NADH-cytochrome b 5 reductase (cb 5 r, EC 1.6.2.2) and that it is inherited in a recessive fashion.
