Similarly, other studies using primers targeting CpG sites in the 5′UTR also showed that none of a total of 112 MPN cases (73 in Fourouclas et al. and 39 in Fernández-Mercado et al.)had methylation of SOCS1 [21, 22] (Figure S1). The gene discussed is SOCS1; the disease is myeloproliferative neoplasm.
