Abstract excerpt
We analyzed the NADH-cytochrome b5 reductase gene of hereditary methemoglobinemia type I and type III, by using PCR-related techniques. The mutation in type I is a guanine-to-adenine substitution in codon 57 of exon 3 of the NADH-cytochrome b5 reductase gene, and the sense of this codon is changed from arginine to glutamine. In type III the mutation is a thymine-to-cytosine transition in codon 148 of exon 5,...
