Located close to ApoE4, yet may independently (also) influence risk of Alzheimer's disease.

A case-control study of 381 patients found a 2x higher risk for Alzheimer's disease associated with the rarer rs2075650(G) allele. 10.1371/journal.pone.0006501

This allele is associated with earlier onset of Alzheimer's disease, by ~7 years. (news) [PMID 19668339OA-icon.png] The data from this study are available online at [1]. The association of this SNP with late-onset Alzheimer's disease was confirmed by a study reported in PLoS Genetics.

The A allele of this SNP is one of 150 identified as relevant to exceptional longevity in 10.1126/science.1190532

Recent work suggests, however, that the linkage disequilibrium between rs2075650 and the ApoE ε4 defining SNP rs429358 means that there may be little, if any, independent effect of rs2075650 on Alzheimer's risk. [2]

A 2020 study has found that rs2075650(G) was found to be associated with high-likelihood Alzheimer's disease cases as when the risk allele was found on an APOE ε3 haplotype. [[https://www.ncbi.nlm.nih.gov/pubmed/24270849 ?dopt=Abstract PMID 24270849 ]OA-icon.png]

[PMID 24270849OA-icon.png] rs2075650 was found to be associated with Alzheimer's disease based on a study by the eMERGE network in which electronic medical records were searched to find clinical associations associated with selected SNPs.
