    Susceptibility
  • to endometrial cancer
  • to age-related hearing impairment
  • to acute lymphoid and myeloid leukemia
  • to vitiligo
  • to head and neck cancer
  • predisposition for developing leukopenia
  • to lung cancer patients by tobacco smokers
  • to non-Hodgkin lymphoma (NHL)
  • to idiopathic male infertility
  • to type-2 diabetes
  • Variant & Polymorphism other
  • idiopathic Parkinson's disease
  • null variants increasing the risk of acute lymphoid and myeloid leukemia
  • GSTM1 null type might be associated with vitiligo
  • GSTM1-null genotype associated with head and neck cancer
  • significant risk for lung cancer concerning tobacco smoking was found in the association of null genotypes for GSTM1 and GSTT1
  • rs1695 AG and the combined AG/GG genotypes were associated with decreased risk of NHL
  • null genotypes (GSTT1 and GSTM1) are a potential biomarker of predisposition for developing leukopenia
  • increased risk of GSTM1 or GSTT1 null genotypes for developing male infertility, but the nondeletion GSTM1 and GSTT1genotypes emerged as protective factors
  • GSTM1 null genotypes are associated with increased risk for senile cataract in Asian populations but not in Caucasian populations (
