Common tests for diagnosing ET include:īlood tests can exclude other causes of a high platelet count (“reactive”). Other patients may consult their physician after experiencing one or more symptoms of ET.īased on diagnostic tests and a review of patient history and symptoms, a physician can determine whether a patient has ET, and whether his/her case can be categorized as having low or high risk. Discovered in 2013 by two independent laboratories (including one funded by the MPN Research Foundation), the identification of the CALR genetic marker has potential implications for treatments and prognosis for those with ET.ĮT is often suspected after a routine blood test shows that a patient has a high platelet count. Nearly a quarter (23.5%) of those diagnosed with MF and ET have a mutation called Calreticulin, or CALR. This mutation leads to hyperactive JAK (Janus kinase) signaling, causing the body to make the wrong number of blood cells. People older than 60 are most likely to develop the condition, although 20% of ET sufferers are under the age of 40.Īpproximately half of all ET patients have a mutation of the JAK2 gene in their blood-forming cells.

Women are 1.5 times more likely than men to develop essential thrombocythemia. Signaling pathways are important regulators of cell growth and development. However, researchers have discovered mutations that alter the activity of proteins that control signaling pathways (important regulators of cell growth and development) in many patients with ET. Like many other MPNs, ET is not a genetically inherited disorder, but there may be a familial predisposition to the disease in some patients. No one knows what causes the onset of essential thrombocythemia (ET) or other myeloproliferative neoplasms (MPNs).
