Associated Genetic Biomarkers

Overview

NCI Definition: An indolent chronic B-cell leukemia resembling classic hairy cell leukemia but shows variant cytologic, hematologic, and immunophenotypic features and is resistant to the conventional therapy applied to hairy cell leukemia. Biologically, it is not related to hairy cell leukemia. [1]

Hairy cell leukemia variants most frequently harbor alterations in TP53, NOTCH2, KDM6A, and BTK [2].

Most Commonly Altered Genes in Hairy Cell Leukemia Variant

TP53 c.217-c.1178 Missense, TP53 V173M, TP53 Mutation, TP53 Missense, and TP53 Exon 5 Mutation are the most common alterations in hairy cell leukemia variant [2].
