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.
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.
Our results did not provide evidence for the association of these SNPs with SALS, suggesting a possible population-specific effect for FLJ10986 and ITPR2 that do not modulate the risk for SALS in the German population.
