The t(9;22) results in the production of a BCR-ABL1 fusion protein. The majority of pediatric and half of adult t(9;22) positive B-ALL involve the minor breakpoint cluster region (m-bcr) encoding a smaller p190 fusion protein in contrast to chronic myelogenous leukemia (CML), where it involves the major breakpoint cluster region (M-bcr). <ref>{{Cite journal|last=Woo|first=Jennifer S.|last2=Alberti|first2=Michael O.|last3=Tirado|first3=Carlos A.|date=2014|title=Childhood B-acute lymphoblastic leukemia: a genetic update|url=https://pubmed.ncbi.nlm.nih.gov/24949228|journal=Experimental Hematology & Oncology|volume=3|pages=16|doi=10.1186/2162-3619-3-16|issn=2162-3619|pmc=4063430|pmid=24949228}}</ref> | The t(9;22) results in the production of a BCR-ABL1 fusion protein.
