Our aim was to test the association of four polymorphisms (rs1671021 in LLGL2, rs753307 in RUVBL2, rs6007897 and rs4044210 in CELSR1) previously identified as ischemic stroke (IS) risk factors in a phased GWAS performed on 6341 Japanese individuals [1].
After DNA sequencing of linkage disequilibrium blocks containing these SNPs, three tag SNPs (rs6007897 of CELSR1, rs1671021</span> of LLGL2, and rs1062708 of RUVBL2) and a nonsynonymous SNP (rs4044210 of CELSR1) were examined for their relation to ischemic stroke in subject panels B and C. Both rs6007897 (A-->G, Thr2268Ala) and rs4044210 (A-->G, Ile2107Val) of CELSR1 as well as rs1671021 (T-->C, Phe479Leu) of LLGL2 were significantly associated with ischemic stroke in subject panel B.
Longitudinal analysis with a generalized estimating equation and with adjustment for age, gender, body mass index and smoking status revealed that rs2116519 of family with sequence similarity 78, member B (FAM78B; P=0.0266), rs6929846 of butyrophilin, subfamily 2, member A1 (BTN2A1; P=0.0013), rs146021107 of pancreatic and duodenal homeobox 1 (PDX1; P=0.0031) and rs1671021 of lethal giant larvae homolog 2 (Drosophila) (LLGL2; P=0.0372) were significantly (P<0.05) associated with the prevalence of hypertension.
