A study by Garg et al. [63] compared CLL patients with monoallelic (n = 143) and biallelic del(13q) (n = 33) as the sole cytogenetic alteration and concluded that there was no difference between the two groups in baseline characteristics (such as white blood cell (WBC) count, absolute lymphocyte count, hemoglobin, platelets, lactate dehydrogenase (LDH), alkaline phosphatase (AP), and β2 microglobulin levels) as well as endpoints including time-to-first treatment (TTFT). The gene discussed is HLA-G; the disease is B-cell chronic lymphocytic leukemia.
