IDH2 R140

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.

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.

Our findings provide evidence that IDH1 hotspot mutations serve as driver alterations in this rare yet distinct molecular subset of PCa. Further studies are warranted to correlate response to androgen deprivation and IDH inhibitors.

The Idyllaâ„¢ IDH1-2 Mutation Assay demonstrates high sensitivity and specificity in detecting IDH1-2 mutations in gliomas across real-world clinical settings. The rate of development of targeted treatments and biomarkers has led to increased demand for rapid results in the clinical diagnostic laboratory. This system is easily integrated into pathology laboratories, facilitating fast turnaround time of IDH1-2 results to clinicians.

In multivariable analyses, RAS and RTK pathway mutations were significantly associated with decreased overall survival, after adjusting for treatment arm, IDH2 variant, and mutational burden. Importantly, enasidenib-mediated survival benefit was more pronounced in patients with IDH2-R172 variants.

Significant differences in GA and immune biomarkers are noted between IDH1/2+ and IDHwt iCCA. IDH1-/2-mutated tumors appear immunologically cold without gLOH. These immunogenomic data provide insight for precision targeting of iCCA with IDH alterations.

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.
