Only the ZNF577 gene showed a differential methylation profile between PV JAK2 V617F positive and controls. This aberrant methylation was correlated with a differential gene expression of ZNF577. No aberrant hypermethylation was found in the SOCS-1 and SOCS-3 genes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>According to our results, an aberrant methylation pattern does not seem to play a crucial role in MPN pathogenesis; nor does it
