We recently reported a joint analysis of genome-wide association (GWA) data on 958 sporadic amyotrophic lateral sclerosis (ALS) cases and 932 controls from Ireland and the publicly available data sets from the United States and the Netherlands. The strongest pooled association was rs10260404 in the dipeptidyl-peptidase 6 (DPP6) gene. Here, we sought confirmation of joint analysis signals in both an expanded Irish and a Polish ALS cohort. Among 287 522 autosomal single-nucleotide polymorphisms (SNPs), 27 were commonly associated on joint analysis of the Irish, US and Dutch GWAs. These 27 SNPs were genotyped in an expanded Irish cohort (312 patients with SALS; 259 controls) and an additional Polish cohort (218 patients; 356 controls). Eleven SNPs, including rs10260404, reached a final P-value below 0.05 in the Irish cohort. In the Polish cohort, only one SNP, rs6299711, showed nominal association with ALS. Pooling of data for 1267 patients with ALS and 1336 control subjects did not identify any association reaching Bonferroni significance (P<1.74 x 10(-7)). The present strategy did not reveal any consistently associated SNP across four populations. The result for DPP6 is surprising, as it has been replicated elsewhere. We discuss the possible interpretations and implications of these findings for future ALS GWA studies both within and between populations.

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.
