Web72.7.2 NADH-Cytochrome B 5 Reductase Deficiency. This is an autosomal recessive disorder. Heterozygotes are asymptomatic although intermittent methemoglobinemia occurs when exposed to certain oxidant drugs. Homozygous deficient patients often have 15–40% MHb and this can increase in the presence of certain oxidants. dnd 5e the feywild
