IGHD and Stereotype distribution in normal and CLL B cells using IGHV1-69/IGHJ3 rearrangements. Bars identify percent sequences (y-axis) using IGHD (A) or assigned to each subset (B) of all normal (dark gray) or CLL (light gray) IGHV1-69/IGHJ3 rearrangements. (A) Percent IGHD distribution among normal and CLL B cells refers to all IGHV1-69/IGHJ3 rearrangements analyzed (stereotypic and nonstereotypic). (B) Percent stereotypic pattern distribution refers to those normal and CLL B cells using IGHV1-69/IGHJ3 rearrangements assigned to subsets only. For each subset, IGHD gene and reading frame are also indicated (in parentheses separated by a slash) in the x-axis.
