چکیده انگلیسی
Common polymorphisms of the Cholestryl Ester Transfer Protein (CETP) gene may predict lower risk of cognitive decline. We investigated the association of cognitive function with CETP genotype in a population-based cohort of 4135 persons aged 35-82 years. Cognitive function was measured with the Ruff Figural Fluency Test (RFFT; worst score, 0 points; best score, 175 points) and CETP I405V and Taq1B genotypes were determined by polymerase chain reaction. RFFT score was not associated with I405V genotype in persons aged 35-64 years. Remarkably, beyond age 65, homozygous valine carriers had higher RFFT scores than heterozygous carriers and noncarriers: RFFT (SD), 52 (21), 49 (18), and 47 (17) points, respectively (p = 0.005). There also was a statistically significant interaction between I405V genotype and age. Beyond age 65, the difference between homozygous valine carriers and noncarriers increased by 0.11 point per year (p = 0.005). RFFT score was not associated with Taq1B genotype. In conclusion, CETP I405V valine homozygosity was associated with better cognitive function in persons aged 65 years or older.
