With a large sample size, we reported the association between JAK2V617F-positive MPNs and 15 tag JAK2 SNPs and the association of rs12342421 being independent of the JAK2 46/1 haplotype in Hong Kong Chinese population.
Genotype-phenotype analysis showed 3 JAK2 SNPs (rs7046736, rs10815148, and rs12342421) to be significantly but reciprocally associated with PV (P < .001 for all; odds ratio = 0.16, 2.72, and 2.46, respectively) and ET (P < .001 for all; odds ratio = 3.05, 0.29, and 0.30, respectively) but not with PMF.
