title: Association between SOD2 T-9C and MTHFR C677T polymorphisms and longevity: a study in Jordanian population.
abstract: BACKGROUND
  Aging in animals is associated with high body oxidative stress, which might affect susceptibility and onset of age-related diseases, and the subsequent life span. Therefore, genes that modulate oxidative stress might play a role in determining longevity. In this study, we investigated whether the gene pool relevant to the SOD2-9T/C and MTHFR 677C/T polymorphisms changes as the Jordanian population ages.
  
  
  METHODS
  Polymorphisms were genotyped in 130 elderly subjects (57 females and 73 males, mean age: 90.01 years) and 135 young control subjects (67 females and 68 males, mean age: 33.43 years).
  
  
  RESULTS
  No significant differences were found in the genotype and allele frequencies of examined SOD2 and MTHFR gene variants between the elderly group and young controls (P > 0.05), nor when each gender was considered separately (P > 0.05).
  
  
  CONCLUSIONS
  SOD2-9T/C and MTHFR 677C/T gene polymorphisms do not seem to be important in Jordanian population for longevity phenotype.
