NP = nonproductive rearrangements, P = productive rearrangements. The AICDA−/− data includes CD19+CD27 and CD19+CD27+ sequences from three patients. The control data comes from previous reports of 4 individuals and three different experiments that collected IgM+, IgM+CD5+, IgM+CD5, IgD+CD27 and IgDCD27+ B cells which represent normal unmutated and mutated populations in peripheral blood. The mutation frequencies were calculated from the number of mutations/total number of bases analyzed or from the total number of bases analyzed from mutated sequences only.
