Overview
Pathophysiology of Hairy Cell Leukemia
Hairy cells are nearly mature, activated clonal cells with signs of VH gene differentiation.[1] They may be related to memory cells.
While there are few genomic imbalances in the hairy cells, the expression of genes is dysregulated in a complex and specific pattern. The cells underexpress 3p24, 3p21, 3q13.3-q22, 4p16, 11q23, 14q22-q24, 15q21-q22, 15q24-q25, and 17q22-q24 and overexpress 13q31 and Xq13.3-q21.[2] It has not yet been demonstrated that any of these changes have any practical significance to the patient.
