More recently, a common germline variant was identified in TERT, which predisposes equally to PV (OR=2.3, allelic χ2P=1.1 × 10−5), ET (OR=2.3, allelic χ2P=2.87 × 10−3) and PMF (OR=2.4, allelic χ2P=2.46 × 10−2) in the Icelandic population11. This evidence concerns the gene TERT and essential thrombocythemia.
