A new report addresses the clinical relevance of DNA variants in chronic myeloid neoplasms (CMNs).
The report is intended to aid clinical laboratory professionals with the management of most CMNs and the development of high-throughput pan-myeloid sequencing testing panels.
The authors list 34 genes they consider “critical” for sequencing tests to help standardize clinical practice and improve care of patients with CMNs.
The Association for Molecular Pathology (AMP) established a CMN Working Group to generate the report, which was published in The Journal of Molecular Diagnostics.
“The molecular pathology community has witnessed a recent explosion of scientific literature highlighting the clinical significance of small DNA variants in CMNs,” said Rebecca F. McClure, MD, a member of the AMP CMN Working Group and an associate professor at Health Sciences North/Horizon Santé-Nord in Sudbury, Ontario, Canada.
“AMP’s working group recognized a clear, unmet need for evidence-based recommendations to assist in the development of the high-quality pan-myeloid gene panels that provide relevant diagnostic and prognostic information and enable monitoring of clonal architecture.”
The increasing availability of targeted, high-throughput, next-generation sequencing panels has enabled scientists to explore the genetic heterogeneity and clinical relevance of the small DNA variants in CMNs.
However, the biological complexity and multiple forms of CMNs have led to variability in the genes included on the available panels that are used to make an accurate diagnosis, provide reliable prognostic information, and select an appropriate therapy based on DNA variant profiles present at various time points.
AMP established its CMN Working Group to review the published literature on CMNs, summarize key findings that support clinical utility, and define a set of critical gene inclusions for all high-throughput pan-myeloid sequencing testing panels.
The group proposed the following 34 genes as a minimum recommended testing list: ASXL1, BCOR, BCORL1, CALR, CBL, CEBPA, CSF3R, DNMT3A, ETV6, EZH2, FLT3, IDH1, IDH2, JAK2, KIT, KRAS, MPL, NF1, NPM1, NRAS, PHF6, PPM1D, PTPN11, RAD21, RUNX1, SETBP1, SF3B1, SMC3, SRSF2, STAG2, TET2, TP53, U2AF1, and ZRSR2.
“While the goal of the study was to distill the literature for molecular pathologists, in doing so, we also revealed recurrent mutational patterns of clonal evolution that will [help] hematologist/oncologists, researchers, and pathologists understand how to interpret the results of these panels as they reveal critical biology of the neoplasms,” said Annette S. Kim, MD, PhD, CMN Working Group Chair and an associate professor at Harvard Medical School and Brigham and Women’s Hospital in Boston, Massachusetts.
