Single-nucleotide polymorphism rs6690993 in FGGY is not associated with amyotrophic lateral sclerosisin a large Chinese cohort.

The single-nucleotide polymorphisms (SNPs) rs6700125 and rs6690993 in FGGY (FLJ10986) were recently reported to be a susceptibility factor for sporadic amyotrophic lateral sclerosis (SALS) in Caucasian populations in genome-wide association studies. However, no such association was observed in other independent genome-wide association studies or replication studies in a European cohort or 2 small sample sizes of Chinese patients. We performed a large case-control study in a cohort consisting of 963 SALS cases and 1039 control subjects to examine the association between the 2 reported SNPs in FGGY and amyotrophic lateral sclerosisin Chinese patients. Our results did not find the SNP rs6690993 in FGGY is associated with Chinese SALS and cannot confirm that this FGGY SNP modulates the risk for SALS in the Chinese population.
