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

Mutation in PDGFRa D842V. Less common than KIT/PDGFRA Mutant GIST, the most common mutation in PDGFRa is exon 18 mutation 1, known as the D842V mutation, is resistant to Gleevec, Sutent, and Stivarga (the first three treatment lines used for the most common GIST diagnoses).

2018 — För patien- ter med EGFR mutation eller genfusion Figuren visar frekvensen av mutationer hos samtliga patienter (n=533) som svarta staplar. Collapse Section The PDGFRA gene provides instructions for making a protein called platelet-derived growth factor receptor alpha (PDGFRA), which is part of a family of proteins called receptor tyrosine kinases (RTKs). Receptor tyrosine kinases transmit signals from the cell surface into the cell through a process called signal transduction. The most common PDGFRA mutations found in GIST tumors occur in exon 18 and are thought to stabilize PDGFRA's tyrosine kinase in an activated conformation.

Pdgfra mutation

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. Our study suggests that patients with melanoma harboring certain PDGFRA mutations may benefit from imatinib and crenolanib treatment. PDGFRA mutations are detected in a small population of melanoma patients.

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.

In sporadic forms of the disease, somatic mutations target either KIT or PDGFRA genes. 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.
