NCIt definition : Human APOBEC3B wild-type allele is located within 22q13.1-q13.2 and is approximately
10 kb in length. This allele, which encodes DNA dC- dU-editing enzyme APOBEC-3B protein,
is involved in the modulation of DNA cytosine deamination. A deletion that fuses the
3' UTR of this gene to the 3' end of the APOBEC3A gene, essentially deletes the APOBEC3B
coding sequence, and may be associated with increased susceptibility to neoplastic
disease.;
NCIt note : The APOBEC3B gene is one of seven related genes or pseudogenes found in a cluster,
thought to result from gene duplication, on chromosome 22. (EntrezGene);
