Names

Common Name: GSTM1 Type: Gene
Chromosome: 1 (NC_000001.11) Locus: NG_009246.1 (GSTM1)
HUGO Symbol: GSTM1 Full Name: glutathione S-transferase mu 1
Exons: 8 Introns: 7

Description:
GSTM1 is a member of the glutathione S-transferase (GST) family of detoxification enzymes, which catalyse conjugation reactions between the reduced form of glutathione (a nucleophile) and a variety of electrophilic compounds, such as environmental toxins and carcinogens. The glutathione system protects cells against damage from oxidative stress by reducing oxygen-free radicals. As oxidative stress would promote sickling of HbS, genetic polymorphisms of GSTs are expected to modulate the phenotype and/or severity of sickle cell disease (SCD). GSTs are encoded by polymorphic genes divided into five classes: α, ζ, μ, π, and θ. The GSTM1 gene encodes a GST that belongs to the μ class, of which null mutations have been linked to the development of specific cancers. The GSTM1 null genotype has been associated with myocardial iron overload in β-thalassemia major patients, as well as with modulation of red-blood cell traits in sickle cell disease. Multiple protein isoforms are encoded by transcript variants of this gene.
