No mutations in the GATA-1 gene detected in patients with acquired essential thrombocythemia.

ABSTRACT

Mutations in the GATA-1 gene have been identified in patients with familial macrothrombocytopenia and Down's syndrome patients with a transient myeloproliferative disorder and/or acute megakaryoblastic leukemia. We screened this gene in 46 patients with essential thrombocythemia and identified only a common single nucleotide polymorphism that is unlikely to be of pathological significance.
