Abstract

JAK2 (V617F) is associated with a genetic predisposition to its acquisition, as it is preferentially found in subjects with a common constitutional JAK2 haplotype known as 46/1 or GGCC. A recent study suggests that a genetic predisposition to acquisition of MPL mutation may exist in sporadic patients, since an association was found with the JAK2 46/1 haplotype. We genotyped 509 patients with myeloproliferative neoplasms (MPN), 7% of which carrying a somatic mutation of MPL Exon 10. We found that the JAK2 GGCC haplotype was closely associated with JAK2 (V617F) (OR 1.84, P <0.001) but not with MPL mutations (OR 0.98), suggesting a different genetic background for these molecular lesions.
