Detection of BRAF V600E mutation in hairy cell leukemia by high- resolution melting analysis / 中华血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the feasibility and diagnostic implication of BRAF V600E mutation identified by high-resolution melting (HRM) assay in patients with hairy cell leukemia (HCL).</p><p><b>METHODS</b>The V600E mutation of BRAF exon 15 in four HCL patients were detected by HRM assay and patients' clinical data were retrospectively analyzed.</p><p><b>RESULTS</b>All four HCL patients were positive for the BRAF V600E mutation, which were identical to the results of DNA sequencing.</p><p><b>CONCLUSION</b>The HRM assay for BRAF V600E mutation provides a useful tool to aid the laboratory diagnosis of HCL with easy operability, accuracy, and low cost.</p>
