Atypical Chronic Myeloid Leukemia, BCR-ABL1- (ACML)

Overview

Atypical Chronic Myeloid Leukemia, BCR-ABL1-negative (ACML) is a rare myelodysplastic/myeloproliferative neoplasm under the MDS/MPN parent in OncoTree. It resembles CML morphologically but lacks the BCR-ABL1 fusion. CALR mutations have been rarely identified in ACML.

Cohorts in the corpus

Recurrent alterations

  • In a follow-up Sanger sequencing screen of 1,345 hematologic cancers, only 1/29 ACML cases carried a CALR exon 9 frameshift indel, confirming that CALR mutations are rare outside the BCR-ABL1-negative MPN spectrum. PMID:24325359

Subtypes

  • No molecular subtypes defined in the current corpus.
