Abstract
Neurotensin modulates dopamine and serotonin transmission in the brain. The study investigated whether genetic polymorphisms in the Neurotensin receptor 1 gene were associated with performance on processing speed and executive function. A total of 129 healthy Chinese-Han volunteers were recruited. Genotyping for three SNPs, including rs6090453, rs6011914, and rs2427422, was analyzed by using a PCR and a restriction fragment length polymorphism analysis. Performances of processing speed and executive function were assessed by using Trail Making Test-A (TMT-A), Wisconsin Card Sorting Test, and Stroop Color-Word Test. We found significant differences in the outcomes of TMT-A score among rs6090453C/G (F (2,126) = 4.405, P = 0.014) and rs2427422A/G (F (2,126) = 7.498, P = 0.001) genotypes. Neurotensin receptor 1 SNP polymorphisms were significantly associated with the variance in processing speed performance in a sample of Chinese college students.
