Abstract

Recently, several studies have investigated the association between the rare mutation of triggering receptor expressed on myeloid cells 2 (TREM2) gene (rs75932628-T) and the risk of late-onset Alzheimer’s disease (LOAD), but they did not draw the same conclusion. Our aim was to investigate the link between the TREM2 polymorphism and LOAD in the Chinese Han population. We examined 786 patients and 803 controls in this study. The rs75932628 polymorphism was evaluated using high-resolution melting analysis and direct sequencing. rs75932628-T (predicted to cause an R47H substitution) was absent in our cohort. We did not find an association between the rs75932628 single nucleotide polymorphism of TREM2 and LOAD in this study. Thus, rs75932628 is unlikely to be related to LOAD in the Chinese Han population.
