These observations suggest that the FIP1L1-PDGFRA rearrangement occurs in an early hematopoietic progenitor and suggests that the molecular pathogenesis for a subset of SMCD patients is similar to that of HES. Screening for the FIP1L1-PDGFRA rearrangement and Asp816Val mutation will advance rational therapy decisions in SMCD.

A novel tyrosine kinase, generated from fusion of the Fip1-like 1 (FIP1L1) gene to the PDGFRA gene, was identified in 9 of 16 patients (56%) with hypereosinophilic syndrome (HES). This fusion results from an approximate 800 kb interstitial chromosomal deletion that includes the cysteine-rich hydrophobic domain 2 (CHIC2) locus at 4q12.

These two proteins can usually be shut down by imatinib and similar drugs, called tyrosine kinase inhibitors, that block the protein’s activity. A novel tyrosine kinase, generated from fusion of the Fip1-like 1 (FIP1L1) gene to the PDGFRA gene, was identified in 9 of 16 patients (56%) with hypereosinophilic syndrome (HES). This fusion results from an approximate 800 kb interstitial chromosomal deletion that includes the cysteine-rich hydrophobic domain 2 (CHIC2) locus at 4q12. The activating mutations in PDGFRA have been linked to the development of GISTs, and up to approximately 10% of GIST cases involve mutations of this gene. The … These observations suggest that the FIP1L1-PDGFRA rearrangement occurs in an early hematopoietic progenitor and suggests that the molecular pathogenesis for a subset of SMCD patients is similar to that of HES. Screening for the FIP1L1-PDGFRA rearrangement and Asp816Val mutation will advance rational therapy decisions in SMCD. Mutation pathogenicity will be verified by the MD Anderson Cancer Center (MDACC) Precision Oncology Decision Support (PODS) team; Has available archival tissue for CKIT or PDGFRA mutation testing; Lymphocyte count >= 500/uL (within 28 days of study treatment initiation) 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). Nine gastrointestinal stromal tumors (16%) had mutations of the PDGFRA gene. 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.

The gene view histogram is a graphical view of mutations across PDGFRA. These mutations are displayed at the amino acid level across the full length of the gene by default. Restrict the view to a region of the gene by dragging across the histogram to highlight the region of interest, or by using the sliders in the filters panel to the left. PDGFRA mutations are reported in about 74% and 55% of gastric and small-intestinal inflammatory fibroid polyps, respectively, 7, 8 and in 6–7% of GISTs.

The presence of a mutation usually predicts poor survival. Patients with C-KIT mutations other than D816V are likely to respond to imatinib (Gleevec) 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. P653L PDGFRA mutation is hitherto unreported.

DISCUSSION Jun 7, 2020 Labcorp test details for Gastrointestinal Stromal Tumors (GISTs), PDGFRA Mutation Analysis. Jan 1, 2021 In contrast, little is known about mechanisms of resistance in PDGFRA-mutant GIST—except for primary or secondary PDGFRAD842V mutations.
