Abstract

We found 20 patients with an immunophenotype consistent with classic hairy cell leukemia and BRAF mutations other than just V600E. Fourteen had 1 non-V600E BRAF mutation and 6 had V600E with 1 (n = 5) or 2 (n = 1) non-V600E BRAF comutations. This study was registered at https://clinicaltrials.gov as #NCT01087333.
