چکیده

A total of 173 samples obtained from adult patients with de novo acute myeloid leukemia (AML) were assayed for exon 3 PTPN11 mutations by single strand conformation polymorphism (SSCP) analysis and direct sequencing. Only three monocytic leukemias had point mutations (1.73%).

The Difference in Initial Leukocyte Count, Bone Marrow Blast Cell Count and CD 34 Expression in Patients with Acute Myeloid Leukemia with and without NPM1 gene Mutation

Background: Mutation in NPM1 gene has been reported to be the most common genetic mutation in de novo acute myeloid leukemia (AML). AML with NPM1 gene mutation usually presents with higher initial leukocyte and blast cell counts and negative CD34 expression. We aimed to investigate the difference of initial leukocyte counts, bone marrow blast cell counts and expression of CD34 among patients wi...

Frequency of DNMT3A Mutations in Patients with Acute Leukemia in Mashhad

Background and Aims: DNA methyltransferase3A (DNMT3A) is necessary for the adjustment of gene expression, and the mutations in the DNMT3A gene are reported in a variety of leukemia cases. DNMT3A mutations are during cancer progression and cause poor prognosis in many leukemias. Thus, this gene can be a target for new treatments. This study aimed to examine the distribution of DNMT3A mutations i...

A Rare Case of Acute Myeloid Leukemia with Translocation (3:3) Presenting with Features of Chronic Myelomonocytic Leukemia

Background: Acute Myeloid Leukemia (AML) with translocation (3,3) is a form of AML that may present de novo or may arise from a previous myelodysplastic syndrome. It is often associated with normal or elevated peripheral blood platelet count and increased bone marrow megakaryocytes with associated multi lineage dysplasia. A subset of patients present with hepatosplenomegaly while a few cases h...
