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. A single mutation, D842V, in this exon accounts for >70% of GIST tumors. PDGFRA PDGFRA Mutation is present in 2.26% of AACR GENIE cases, with lung adenocarcinoma, colon adenocarcinoma, cutaneous melanoma, conventional glioblastoma multiforme, and gastrointestinal stromal tumor having the greatest prevalence [ 4 ].

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 FDA approved Ayvakit based on the This test is used to detect the genetic mutation FIP1L1-PDGFRA, a rare abnormal gene sequence that causes excessive growth of eosinophils, a type of white blood cell. FIP1L1-PDGFRA testing may be used to help determine the cause of a persistently elevated number of eosinophils, as determined by a complete blood count (CBC) , after other tests have ruled out more common secondary (reactive) causes.

(The FIP1L1-PDGFRA mutation was the first description of a gain of function mutation resulting from an interstitial deletion instead of a chromosomal translocation.) The FIP1L1-PDGFRA fusion gene consists of the 5'-end of FIP1L1 united to the 3'-end of PGDFRA at variable breakpoints in both genes extending over a 40 kilobase region in FIP1L1 and a small region of exon 12 in PDGFRA . Expression of PDGFRA (CD140a, GAS9, PDGFR2) in cancer tissue.

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 +.

PDGFRA mutation analysis. Among the 29 GIST cases without a KIT mutation, a mutation in PDGFRA was detected in three cases (3.23%, 3/93; 10.34%, 3/29). Only one GIST patient with a mutation in PDGFRA on exon 18, which corresponded to a Val 824 internal GTC>GTT base point mutation, also had a mutation in exon 11 of KIT, which corresponded to a L576P point mutation ().

PDGFRA is also a member of the type III receptor tyrosine kinase family, and again mutation leads to constitutive activation of the receptor triggering downstream

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. 5, 6 PDGFRA exon-14 mutations occur in <1% PDGFRA germline mutation in a family with multiple cases of gastrointestinal stromal tumor. Familial gastrointestinal stromal tumor (GIST) is a rare autosomal dominant genetic disorder associated with KIT germline mutations. In sporadic forms of the disease, somatic mutations target either KIT or PDGFRA … PDGFRA (platelet-derived growth factor receptor, alpha polypeptide) encodes the platelet-derived growth factor receptor alpha protein.

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.

Sep 1, 2019 No mutations were identified in the platelet-derived growth factor receptor alpha ( PDGFRA) gene via molecular genetic analysis. DISCUSSION

A subset of GISTs, however, contains mutations in the homologous kinase platelet derived growth factor receptor alpha (PDGFRA), and the most common of these Jan 9, 2020 stromal tumor who harbor platelet-derived growth factor receptor alpha exon 18 mutation, including PDGFRA D842V mutations. A common feature of mutations in KIT and in the gene for PDGFRA is that they are oncogenic, meaning that they initiate the cancer and drive the tumor.
