| May-Hegglin anomaly (MHA) is a rare autosomal disorder which is characterized by triad of thrombocytopenia, giant platelets and Dohle like inclusion bodies in granulocytes. This is the first report of
MHA and its mutation from Iran.
The specimen of two patients (father 51 and son 15 y/o) collected with EDTA and tri-sodium citrate anticoagulants. CBC and peripheral blood smear studied by automatic cell counter and microscopic examination, respectively. Direct sequencing of extracted DNA of certain exons of MYH9 gene was performed. Both patients had demonstrated the diagnostic triad of MHA. Mutations showed homozygous and heterozygous pattern in the father and the son, respectively.
This is the first report of MHA from Iran. The mutation of both patients was E1841K which is the most common type among MYH9 mutations in MHA. The most interesting finding was the homozygous mutation that did not entail any clinical severity. |
