IDH2 R140Q

Controls and acceptable ranges were also established for each mutation during validation. This study suggests that the QuantStudio 3D Digital PCR assay is a quantitative, sensitive, and reproducible platform for monitoring MRD in AML patients.

IDH1/2 mutations are identified in a small subset of NSCLCs. Our findings suggest that >25% of these mutations are hematopoietic in origin with important implications for diagnosis and management of these patients. Among those with mutations arising from the lung neoplasm, IDH1/2 mutations were primarily seen in conjunction with another driver and were subclonal in nature, suggesting patterns of clonal heterogeneity and evolution.

The Idylla IDH1-2 Mutation Assay Kit performed on the Biocartis Idylla system demonstrated a rapid and cost-effective alternative to the standard approaches. This assay can be used to evaluate clinically relevant IDH variants in a much shorter turnaround time and from limited biological samples, which makes this a preferred technique to develop clinical tests for diagnosis, prognosis, and evaluation of treatment in AML.

These mutations are targetable using agents such as ivosidenib and vorasedinib in AML... The Biocartis Idylla IDH1-2 mutation assay shows good concordance with ddPCR and an LOD of 2.5% VAF. Though the analytical sensitivity of this assay is lower than ddPCR, this may not be a limitation in acute, newly diagnosed patients presenting with increased blast counts. This assay offers the advantage of direct specimen testing for PB and BM without DNA extraction with faster turnaround time than other methods.

The AML-VAC-XS15-01 study was approved by the Ethics Committee of the Bavarian State medical association and the Paul-Ehrlich Institut (P01392). Clinical trial results will be published in peer-reviewed journals.

With advancements in molecular diagnostics and precision therapy, IDH inhibitors such as ivosidenib, vorasidenib and enasidenib are now mainstay in management of patients with a susceptible mutation. The Idyllaâ„¢ IDH1-2 Mutation Assay Kit (RUO) is a fully automated qPCR assay for the qualitative detection of 15 common mutations in IDH1 (R132C/H/G/S/L) and IDH2 (R140Q/L/G/W, R172K/M/G/W/S) at codon level. The Idyllaâ„¢ IDH1-2 Mutation Assay Kit demonstrates a high concordance with established reference methods across a range of different specimen types.

Among the 27 healthy germline CEBPA-mutated carriers, we detected a pre-leukemia clone harboring a pathogenic IDH2 variant (R140Q)in one individual. These findings should aid in the genetic counseling and management of AML patients and healthy carriers with germline CEBPA mutations.

The autocrine cytokines, including GM-CSF, LIF, and OSM, contribute to constitutive STAT3/5 activation in TF-1(R140Q) cells, thereby modulating IDH2/R140Q-mediated malignant proliferation in TF-1 cells. Targeting STAT3/5 phosphorylation may be a novel strategy for the treatment of AML in patients harboring the IDH2/R140Q mutation. Video Abstract.
