Abstract:
Activation-induced cytidine deaminase (AICDA) initiates somatic hypermutation and class-switch recombination of immunoglobulin (Ig) genes and induces mutations also in non-Ig genes. AICDA aberrant expression was detected in B-lineage acute lymphoblastic leukaemia (B-ALL), particularly BCR/ABL1+ B-ALL; patients expressing AICDA carried more copy number alterations than 'AICDA-negative' cases. To determine the role of AICDA, AICDA expression and gene expression profiling were studied in adult BCR/ABL1+ B-ALL. Patients displaying the full-length isoform AICDA are characterized by up-regulation of DNA repair/replication and cell cycle genes, suggesting their involvement in the genetic instability of BCR/ABL1+ B-ALL.
