My husband has been having high WBC for almost a year ( routine blood test ) He saw a hematologist... he did blood work and told him he had the JAX2 gene mutation. Dr said he may always have a slightly high WBC but nothing can be done. If it got worse, then he would order a bone marrow biopsy. He told him to return in 6 months. I decided to ask his family Dr to repeat the blood work in 3 months.. WBC was 17 and this time his platelets were high too .. 1 million. Now the hematologist put him on Hydroxyurea ( 500 mg X 2/day ), a baby aspirin and ordered weekly blood test for the next 5 weeks. The Dr changed his mind about the bone marrow test.. he said since we know that this is all coming from the Jax2 gene , it is not necessary. THOUGHTS?
