title: Chronic lymphocytic leukemia patients with a V1-69 gene rearrangement do not have inferior survival with respect to patients that express other unmutated V(H) genes.
abstract: Recent studies indicate that V(H) gene usage in B-CLL may have prognostic impact independently of V(H) gene mutation status. The V1-69 gene is the most frequently rearranged V(H) gene in B-CLL and is almost always unmutated. We therefore investigated whether patients with a V1-69 gene rearrangement differ in clinical course and outcome with respect to patients expressing other unmutated V(H) genes. We show that V1-69 B-CLLs constitute a uniform group of patients that more often present at advanced clinical stages and require early treatment, but their survival does not differ significantly from patients with other unmutated V(H) genes.
