23andMe blog At rs12340895(G) (equivalent to rs12343867 in the study) had nearly four times higher odds of developing V617F-positive MPN compared to people without the disease. 23andMe recently replicated this association, though we see a smaller effect — in our database, people with a G at rs12340895 have about two times the odds of developing V617F-positive MPN compared to people without the disease. n A at rs3780374 in the JAK2 gene (equivalent to rs4495487 reported in the study and highly correlated with rs12343867) have about three times higher odds of developing V617F-positive MPN compared to individuals without the A version.
The following SNPs are (all) associated with the JAK2 46/1 haplotype that appears to predispose to V617F-positive neoplasms; since they are all part of one haplotype (and are not independent of one another), having one usually implies having the others as well.
