Abstrakt: Aim: Chronic lymphocytic leukemia (CLL) is a highly heterogenous hemopathy. Genetic stratification of CLL patients has important prognostic and therapeutic values – mainly immunoglobulin heavy chain variable region gene (IGHV) mutational status and the presence of cytogenetic abnormalities. The genetics of CLL in Lebanon is scarcely described in the literature. Patients & methods: In this work, we studied the genetic biomarkers of 312 Lebanese CLL patients. Results: Prominent IGHV genes were IGHV4-34, IGHV1-69 and IGHV3-30; and CLL #1 and #5 presented major subsets. Some similarities as well as major differences were highlighted when comparing our data with previously published data. Conclusion: The distribution of IGHV alleles in our series differed from previously described distributions, suggesting involvement of antigenic selection and regional variables in CLL pathogenesis.
