KIT and PDGFRA Mutations and the Risk of GI Stromal Tumor Recurrence. Heikki Joensuu, Piotr Rutkowski, Toshirou Nishida, Sonja E. Steigen, Peter Brabec,
PDGFRA -associated chronic eosinophilic leukemia is a form of blood cell cancer characterized by an elevated number of cells called eosinophils in the blood. These cells help fight infections by certain parasites and are involved in the inflammation associated with allergic reactions. 2016-09-21 · There were 80 tumors (7.2%) with a PDGFRA mutation: 66 in exon 18, 11 in exon 12, and three in exon 14. Transient expression of representative PDGFRA isoforms in CHO cells revealed imatinib sensitivity of exon 12 mutations (SPDHE566-571R and insertion ER561-562) and an exon 14 substitution (N659K). PDGFRA mutations transform myeloid cells To screen which of the PDGFRA point mutants possess transforming activity, we retrovirally expressed each mutant in factor-dependent murine myeloid 32D cells and analyzed the resulting cell lines for factor-independent cell growth. 2005-10-24 · Types, Frequency and Distribution of PDGFRA Exon 14 Mutations among GISTs.
Identification of mutations is informative for sensitivity or resistance to tyrosine kinase inhibitor (TKI) therapy. PDGFRA (platelet-derived growth factor receptor, alpha polypeptide) encodes the platelet-derived growth factor receptor alpha protein. PDGFRA mutations lead to kinase activation. Mutant PDGFRA has been implicated in the pathogenesis of a number of cancers. PDGFRA Mutation Analysis - Mutations in the PDGFRA gene are found in 5-8% of gastrointestinal stromal tumors (GISTs), especially in the 40-50% of KIT wild type GISTs. PDGFRA mutations also have been described in synovial sarcomas (SSs) and malignant peripheral nerve sheath tumors (MPNST).

This phase II trial studies the effect of avapritinib in treating malignant solid tumors that have a genetic change (mutation) in CKIT or PDGFRA and have spread to
These cells help fight infections by certain parasites and are involved in the inflammation associated with allergic reactions. The gene view histogram is a graphical view of mutations across PDGFRA.
Circulating tumor DNA (CtDNA) harboring tumor-specific c-Kit protooncogene (cKIT) or platelet derived growth factor receptor alpha (PDGFRA) mutations was detected in in gastrointestinal stromal tumor (GIST). PDGFRA (platelet-derived growth factor receptor, alpha polypeptide) encodes the platelet-derived growth factor receptor alpha protein. PDGFRA mutations lead to kinase activation. Mutant PDGFRA has been implicated in the pathogenesis of a number of cancers. P653L PDGFRA mutation is hitherto unreported. 28 Highly conserved amino acid alignment of tyrosine kinase I PDGFRA and KIT domains shows correspondence between codon 653 of PDGFRA and codon 649 of
PDGFRA mutations are detected in a small population of melanoma patients.

PDGFRA gene mutations occur in approximately 30% of gastrointestinal stromal tumors (GISTs) that are wild type for KIT mutation, and in 7% of GISTs overall. PDGFRA and KIT mutations are mutually exclusive in …
GISTs with such mutation are resistant to imatinib. PDGFRA Jul 1, 2020 The dose-expansion part of the study included patients with an unresectable PDGFRA D842V-mutant gastrointestinal stromal tumour regardless Feb 18, 2019 Platelet-Derived Growth Factor Receptor Alpha (PDGFRA) mutations occur in approximately 5–7% of gastrointestinal stromal tumours (GIST). Sep 5, 2018 Mutations in the PDGFRA gene may induce activation of constitutive has been used to treat KIT/PDGFRA mutated GISTs (1); however, the Jan 10, 2020 For patients with PDGFRA D842V mutation, the ORR was 89% (95% CI, 75-97) with 8% having complete response and 82% having partial May 24, 2016 However, some KIT/PDGFRA wild-type GISTs with KIT mutations in other exons were occasionally reported.

All patients with PDGFRA D842V-mutant gastrointestinal stromal tumours were enrolled on the basis of local available mutation testing. On study, PDGFRA mutation status was determined centrally in plasma with the OncoBEAMPDGFRA assay (Sysmex Hamburg, Hamburg, Germany) for dose escalation to evaluate pharmacodynamics and to explore the mechanism
