title: Association between low self-rated health and heterozygosity for -110A > C polymorphism in the promoter region of HSP70-1 in aged Danish twins.
abstract: We have studied the possible association between the -110A > C polymorphism in the promoter region of one of the heat shock protein genes HSP70-1 with human longevity in a cohort of aged Danish twins. This cohort includes individuals aged between 70 and 91 years (mean = 75.6 years), who are categorized according to the presence or absence of various diseases and according to the various, age-related parameters for which a genetic component has already been defined. Four hundred DNA samples from the cohort were genotyped using real-time PCR. Aging phenotypes (diseases, physical and cognitive functioning) were compared with regard to genotype. Of all the aging phenotypes studied, self-rated health and relative self-rated health, which represent an individual's overall sense of physical well-being and which have been shown to be both predictors of survival at older ages and better indicators of future survival than objectively measured health status, were associated with the polymorphism. An association was found between low self-rated health and heterozygosity for -110A > C polymorphism in the promoter region of HSP70-1 in aged Danish twins.
