Neither the butyrylcholinesterase K variant nor transferrin C2 variant confers a risk for Alzheimer's disease in Koreans

초록

To investigate the possible involvement of the butyrylcholinesterase (BCHE) K variant and transferrin (TF) C2 variant in the manifestation of Alzheimer's disease (AD), we analyzed the BCHE, TF and apolipoprotein E (APOE) genotypes of 164 sporadic AD patients and 239 normal elderly controls. The frequencies of the BCHE K and TF C2 did not differ between the AD patients and controls (P > 0.1). The occurrence of the APOE ε4 did not influence the distribution of the BCHE K and TF C2 variants (P > 0.1). No linkage disequilibrium between the BCHE K and TF C2 was observed either in both the AD patients and controls (P > 0.1). In conclusion, neither the BCHE K nor the TF C2 confers a risk for AD.
