Summary

The BRAF V600E mutation has recently been described in all cases of hairy cell leukaemia (HCL). We have developed and validated a rapid and sensitive high-resolution melting analysis (HRMA) assay that detects BRAF exon 15 mutations when hairy cells are as low as 5–10% in a sample. All 48 HCL patients were positive for the BRAF V600E mutation, while 114 non-HCL cases were all V600E negative. Interestingly, we detected a novel BRAF D594N mutation in one patient with multiple myeloma. The HRMA assay offers a useful tool to aid the laboratory diagnosis of HCL.
