PV indicates polycythemia vera; ET, essential thrombocythemia; SNP; single nucleotide polymorphism; N, number; MAF, minor allele frequency; JAK2, Janus kinase 2; EPOR, receptor for erythropoietin; CI, confidence interval.
Number of persons with and without the disorder successfully genotyped for the particular SNP locus.
Minor allele frequencies of those with and without the disorder. Allele defined as “minor” based on frequency of the particular allele in the overall study population. Allele frequencies for HapMap CEU population are indicated separately (see footnote ‡).
Frequency of the allele in the HapMap Project CEU population.
P values computed under an additive genetic model.
Odds ratios and confidence intervals computed under a dominant genetic model.
