Survival of patients with primary myelofibrosis.
<p>Patients were categorized according they were diagnosed with prefibrotic myelofibrosis, myelofibrosis-fibrotic type with early bone marrow fibrosis (grade 1) or myelofibrosis-fibrotic type with advanced bone marrow fibrosis (grade 2 or 3).</p

Immunohistochemistry for NMMHC-IIA in the liver biopsy from one patient with MYH9-RD.
<p>Liver biopsy from a 10-years-old patient with MYH9-RD caused by the p.T1155A mutation of MYH9 with persistently elevated AST, ALT and GGT. (A, B): Immunohistochemistry for NMMHC-IIA showed a signal (brown, horseradish peroxidase staining) concentrated close to the hepatocytes' plasma membrane. The distribution of NMMHC-IIA was not significantly different from that from a healthy control (C, D). Specimens were counterstained with Meyer's haematoxylin. Scale bars correspond to 10 µm.</p
Frequency of abnormal liver tests depending on the location of the MYH9 gene mutation.
<p>Mutations involving the motor domain and tale domain regions of the gene are indicated. No significant differences in the distribution of liver test alteration between the two locations of the gene defect were evident.</p
