No association of five candidate genetic variants with amyotrophic lateral sclerosis in a Chinese population

Abstract

Recently, 5 single nucleotide polymorphisms (SNPs), rs2306677 in the inositol 1,4,5-triphosphate receptor 2 gene (ITPR2), rs1541160 in the kinesin-association protein 3 gene (KIFAP3), rs6690993 and rs6700125 in the FLJ10986 gene, and rs10260404 in the dipeptidyl-peptidase 6 gene (DPP6) have been reported to be associated with the risk of developing sporadic amyotrophic lateral sclerosis (SALS) in Caucasian populations. However, this association is not consistent among different studies and yet to be tested in Chinese SALS patients. We examined the above SNPs in a large cohort consisting of 395 SALS patients and 288 controls from Southwest China. Our results suggest that these SNPs are unlikely to be a common cause of SALS in Chinese populations. © 2012 Elsevier Inc..
