Abstract excerpt
The initial event of somatic hypermutation (SHM) is the deamination of cytidine residues by activation-induced cytidine deaminase (AID). Deamination is followed by the replication over uracil and/or different error-prone repair events. We sequenced 659 nonproductive human IgH rearrangements (IGHV3-23*01) from blood B lymphocytes enriched for CD27-positive memory cells. Analyses of 6,912 unique, unselected...
