Analysis showed, (i) Increased risk between the single nucleotidepolymorphisms (rs641120, rs1010159) and Alzheimer's disease susceptibility inAsian populations, (ii) Single nucleotide polymorphism rs689021 was associatedwith decreased risk in Caucasians, and (iii) Single nucleotide polymorphismrs641120 was detected as a decreased risk in both populations.
We conducted a study of 7 single nucleotide polymorphisms (SNPs), rs668387, rs689021, rs641120, rs1699102, rs3824968, rs2282649, and rs1010159, in the SORL1 gene that were associated to AD in previous studies.
In the present study we investigated the association of SORL1 gene variants (rs2070045 (SNP19), SORL1-18ex26 (SNP21), rs3824968 (SNP23), rs1010159 (SNP25)) with AD risk by using Cox proportional hazard model and Kaplan-Meier survival analysis in 349 AD patients and 483 controls, recruited from a multicenter study of the German Competence Network Dementias.
