Abstract
We present here a unifying hypothesis for the molecular mechanism of somatic hypermutation and somatic gene conversion in IgV genes involving reverse transcription using RNA templates from the V-gene loci to produce cDNA which undergoes homologous recombination with chromosomal V(D)J DNA. Experimental evidence produced over the last 20 years is essentially consistent with this hypothesis. We also review evidence suggesting that somatically generated IgV sequences from Blymphocytes have been fed back to germline DNA over evolutionary time.
