A-to-I RNA editing is the most common non-transient epitranscriptome modification. It plays several roles in human physiology and has been linked to several disorders. Large-scale deep transcriptome sequencing has fostered the characterization of A-to-I editing at the single nucleotide level and the development of dedicated computational resources.

Transcriptional regulation of the gene is complex and involves several regulatory elements including a large element at the 3' end of the gene locus (3'RR). Animal models have demonstrated an essential role of the 3'RR in the ability of B cells to express high affinity antibodies and to express different antibody classes.

In healthy humans, the concentration of each class of circulating immunoglobulins (Igs) has stable but different levels, due to several control mechanisms that also involve a duplicated version of the 3'RR on the chromosome 14 (chr14). The classes' equilibrium can be altered during infections and in other pathological conditions.
