We and others have previously reported linkage to schizophrenia on chromosome 10q25-q26 but, to date, a susceptibility gene in the region has not been identified. We examined data from 3606 SNPs mapping to 10q25-q26 that had been typed in a genome-wide association study (GWAS) of schizophrenia (479 UK cases/2937 controls). SNPs with p<0.01 (n=40) were genotyped in an additional 163 UK cases and those markers that remained nominally significant at p<0.01 (n=22) were genotyped in replication samples from Ireland, Germany and Bulgaria consisting of a total of 1664 cases with schizophrenia and 3541 controls. Only one SNP, rs17101921, was nominally significant after meta-analyses across the replication samples and this was genotyped in an additional six samples from the US/Australia, Germany, China, Japan, Israel and Sweden (n= 5142 cases/ 6561 controls). Across all replication samples, the allele at rs17101921 that was associated in the GWAS showed evidence for association independent of the original data (OR 1.17 (95% CI 1.06-1.29), p=0.0009). The SNP maps 85kb from the nearest gene encoding fibroblast growth factor receptor 2 ( FGFR2 ) making this a potential susceptibility gene for schizophrenia
