Introduction: Multiple types of mutations in the BCR-ABL1 kinase domain have been reported. We previously reported a common alternatively spliced BCR-ABL mRNA with a 35-nucleotide insertion (35INS). We report three novel alternative splicing mutants expressed as the dominant transcripts in patient with chronic myelogenous leukemia and resistance to kinase inhibitors.

Rare cases of CML are characterized by an e19-a2 type mRNA with a corresponding p230 protein. In Ph+ ALL, the majority of cases harbor an e1-a2 BCR-ABL1 mRNA transcript, producing a p190 protein. Quest Diagnostics scientists will present results of three studies revealing the effect of genomic abnormalities on the diagnosis and treatment of chronic myeloid leukemia (CML) and prostate cancer during the 45th Annual Meeting of the American Society of Clinical Oncology ( ASCO ), scheduled for May 29 through June 2 in Orlando, FL . Plasma cTK activity was closely correlated with cellular BCR-ABL1 kinase activation as indicated by phosphorylation of the downstream signaling proteins CRKL (P < 0.001) and STAT-5 (P= 0.003). However, cTK activity was not associated with BCR-ABL1 transcript level and was independent of BCR-ABL1 mutation type.

In addition, scientists from Quest Diagnostics and M.D. Anderson Cancer Center identified three novel (previously undescribed) mutations along the BCR-ABL tyrosine kinase that may constitute a new class of mutations that "confer significant drug resistance" to imatinib therapy by expressing a truncated BCR-ABL1. Abstract title: "BCR-ABL1 truncation due to premature translation termination as a mechanism of resistance to kinase inhibitors."

BCR-ABL1 splice variants and uses thereof Patent number: 9593378 Abstract: The present invention is based on BCR-ABL1 splice variants which result from insertion and/or truncation of the bcr-abl1 transcript and the finding that these variants provide resistance to kinase domain inhibitors such as imatinib, nilotinib and dasatinib. Quantitative – Quantitative BCR-ABL1 Translocation Detection by RT-PCR for CML and ALL. Clinical Use: This assay can detect three different types of BCR-ABL1 fusion transcripts associated with CML, ALL, and AML:e13a2 (previously b2a2) and e14a2 (previously b3a2) (major breakpoint, p210), as well as e1a2 (minor breakpoint, p190). BCR-ABL1 transcript levels ≤10% at 3 months, <1% at 6 months, and ≤0.1% from 12 months onward, define optimal response, while >10% at 6 months and >1% from 12 months onward define failure 2017-09-01 · The overall correlation in percentage BCR-ABL1 between samples stabilized in TRI Reagent compared to whole blood across patient groups was R 2 = 0.89. Several studies have reported on the inaccuracy of the GeneXpert for BCR-ABL levels above 10% (Jobbagy et al., 2007, López-Jorge et al., 2012, Enjeti et al., 2015).

QIAGEN GmbH, QIAGEN Strasse 1, 40724 Hilden, GERMANY R3. 1072509EN Screening was conducted by first amplifying the fusion BCR-ABL1 transcript, to ensure that normal ABL1 was not amplified, then sequencing the ABL1 kinase domain coding region. We discovered 3 not previously described splice mutants, present in one patient each. All 3 showed >90% mutant transcript.

For new patients, Quest Diagnostics will test for both the P210 isoform (e13a2 and e14a2 transcripts) and the P190 isoform (e1a2 fusion).
