BACKGROUND/STUDY CONTEXT: The common 1936A→G transition (rs203462) in the AKAP10 gene encoding the A-kinase-anchoring protein 10 has been recently associated with negative prognosis in the aging European American population (60 to 79 years old). The aim of this study was to see the effects of this transition on allele frequency in very long-lived Poles. AKAP10 genotype and allele distributions were analyzed in Polish subjects: 148 nonagenarians (95 to 103 years old) and 200 healthy newborn controls, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Distributions were separated according to gender and χ(2) tests used to analyze possible differences. No significant differences were found in genotype or allele distribution between the age groups, for either gender. Percentages of GG AKAP10 homozygotes were slightly greater in the very old subjects than in the newborns (12.2% vs. 9.0%, respectively), and the G allele percentages were very similar (males, 30.7% and 33.0%; females, 34.1% and 35.8%; respectively). The authors conclude that differences in study results between European Americans (60 to 79 years old) and Poles (≥95 years old) result from either (1) geographical location; or (2) the influence of this polymorphism on groups of people differing in genetic background or environmental history; or (3) the time window affected, including extreme age. Further studies with full age-frequency distributions are needed to clarify these results.
