title: Mitochondrial DNA in polish centenarians.
abstract: Mitochondrial haplogroups can differ in frequency of occurrence in those who are 100 years old and in the rest of the population. These differences are not universally observed; moreover, they are population-specific. We analyzed the haplogroups in 97 Polish 100-year-olds and compared them with those of more than 145 people who served as controls. No statistically significant differences were observed. In additions, we checked D-loop sequences in 31 controls and in some of the centenarians. Statistically significant differences were found for sites 73 and 152 in the D-loop.
