NCIt definition : Human GSTZ1 wild-type allele is located in the vicinity of 14q24.3 and is approximately
11 kb in length. This allele, which encodes maleylacetoacetate isomerase protein,
plays a role in the metabolism of glutathione, aromatic amino acids, dichloroacetic
acid and maleylacetoacetate. Various haplotypes of this gene affect the rate of metabolism
of dichloroacetate (DCA) and other halogenated carboxylic acids. Mutations in the
gene are associated with maleylacetoacetate isomerase deficiency.;
