Heavy Chain Variable-Region Gene;
NCIt synonyms : Pregerminal Center Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma; CLL/SLL with Unmutated IGVH; Chronic Lymphocytic Leukemia Small Lymphocytic Lymphoma with Unmutated Immunoglobulin
Heavy Chain-Region Gene;
NCIt definition : A recently recognized variant of chronic lymphocytic leukemia/small lymphocytic lymphoma
(CLL/SLL) that lacks somatic hypermutations of the Immunoglobulin heavy chain (IGH)
genes, implying pregerminal center B-cell origin. Microarray gene expression profiling
studies have demonstrated the expression of ZAP-70 gene (Syk family tyrosine kinase)
in this subset of CLL/CLL. Patients with this variant of CLL/SLL have an unfavorable
prognosis compared to those with somatic hypermutations of the IGH genes, with a median
survival of approximately 6-8 years.;
