Hi Debs,

Thanks for your question. The short answer is yes! Essential Thrombocythaemia (ET) is in a class of diseases called Myeloproliferative neoplasms. Your consultant would have checked your BCR -ABL to rule out CML (chronic myeloid leukaemia). He/ she also would have checked for JAK-2.

JAK 2 (Janus kinase 2 ) is a protein which regulates blood cell production and can be mutated in ET. The mutation is an acquired mutation and affects approx. 50% of ET patients.

This link will take you to MPN Voice which is based at Guys & St Thomas'. They are a national charity providing information, patient support and patient information days locally. They have loads of information and advice for sufferers of ET.

I hope this helps, if you have any other questions, please come back to me
