Associated Genetic Biomarkers

Overview

NCI Definition: A neoplasm of small B-lymphocytes with "hairy" projections in bone marrow, spleen, and peripheral blood. Most patients present with splenomegaly and pancytopenia. (WHO, 2001) [1]

Hairy cell leukemias most frequently harbor alterations in BRAF, ATM, NF1, EP400, and DNMT3A [2].

Most Commonly Altered Genes in Hairy Cell Leukemia

BRAF V600E, BRAF Mutation, BRAF Exon 15 Mutation, BRAF Codon 600 Missense, and ATM Mutation are the most common alterations in hairy cell leukemia [2].
