Abstract
We describe a common mutation of the MYH gene, which is involved in the repair of oxidative damage to DNA, and its relationship to age, levels of 8-OHdG, and circulating levels of interleukin-1. We studied 1146 "healthy" and 562 unselected Chinese subjects. We observed a reverse insertion of the AluYb8 sequence (AluYb8MYH) to be homozygous in approximately 25.8% of the healthy Chinese population age 20-29 years, with the incidence of homozygosity decreasing to 15.7% by age 50-59 years. Because subjects were selected on the basis of absence of disease during medical screening, this suggests that homozygosity for this gene has a marked impact on the development of age-related or chronic diseases or mortality. Because the MYH gene is involved in DNA repair we assessed whether homozygous carriage of this gene was associated with increased levels of 8-OHdG in the leukocytic DNA of carriers. The level of 8-OHdG increased from 3.8 8-OHdG/10(6) dG in wild-type carriers to 10.8 8-OHdG/10(6) dG in homozygous carriers, suggesting that the presence of the mutation was associated with impaired DNA repair. Because this mutation might be associated with the increased development of age-related or chronic disease and inflammation, we also meas...Continue Reading
