PDGFRA Mutation is an inclusion criterion in 4 clinical trials for melanoma, of which 4 are open and 0 are closed. Of the trials that contain PDGFRA Mutation and melanoma as inclusion criteria, 1 is phase 1 (1 open), 2 are phase 1/phase 2 (2 open), and 1 is phase 2 (1 open) [ 5 ]. Colorectal Carcinoma +.

These cells help fight infections by certain parasites and are involved in the inflammation associated with allergic reactions. 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 2015-01-20 2019-09-01 2019-07-26 2005-10-24 2020-07-01 Platelet Derived Growth Factor Receptor Alpha (PDGFRA) mutations occur in only about 5–7% of gastrointestinal stromal tumors (GIST), notably with alterations on exons 12/14/18.

MedGen UID: Gastrointestinal stromal tumors (GIST) harboring activating mutations of PDGFRA respond to imatinib, with the notable exception of the most common mutation, D842V. Avapritinib is a novel, potent KIT/PDGFRA inhibitor with substantial clinical activity in patients with the D842V genotype. A molecular genetic abnormality indicating the presence of a mutation in the PDGFRA (platelet-derived growth factor receptor, alpha polypeptide) gene on chromosome 4q12.

Amplifications involving MET (38%, n = 3/8) and PDGFRA (25%, n = 2/8) were present only in the sarcomatous components, whereas mutation affecting ERBB4 (25%, n = 2/8) and amplifications of CCND1 and FGF3/4/19 (38%, n = 3/8) were present only in the carcinomatous components, indicating their involvement in the clonal evolution of HCS.

Almost all KIT mutations occur in exon 9, 11, 13, or 17, and PDGFRA mutations in exons 12, 14, or 18. 1 Ten percent to 15% of GISTs that lack KIT and PDGFRA mutations are often referred to as wild-type GISTs, though they may have Amplifications involving MET (38%, n = 3/8) and PDGFRA (25%, n = 2/8) were present only in the sarcomatous components, whereas mutation affecting ERBB4 (25%, n = 2/8) and amplifications of CCND1 and FGF3/4/19 (38%, n = 3/8) were present only in the carcinomatous components, indicating their involvement in the clonal evolution of HCS. We also found that the sites of mutation in c-KIT and PDGFRA correlated with specific anatomic sites, as previously described in the literature. 20, 21 Specifically, 9 of 10 tumors showing mutations in exon 9 of c-KIT were located in the small intestine, and all 7 cases with PDGFRA mutations were found in the stomach. 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 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. Up to 85% of GIST tumors contain mutations in one of two genes, PDGFRA and KIT. These mutations lead to the production of aberrant KIT and PDGFRA proteins that drive the cancer, explained Dr. Heinrich.
