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. For example, mutations are found in gastrointestinal stromal tumors (GIST; PMID: 15928335PMID: 12522257), and fusions in hypereosinophilic syndrome (PMID: 12660384) and dermatofibrosarcoma protuberans (PMID: 8988177).

PDGFRA is altered in 2.80% of all cancers with non-small cell lung carcinoma, malignant glioma, melanoma, colorectal adenocarcinoma, and breast carcinoma having the greatest prevalence of alterations [3].

PDGFRA GENIE Cases - Top Diseases

The most common alterations in PDGFRA are PDGFRA Mutation (3.01%), PDGFRA Mutation (somatic) (3.01%), PDGFRA Amplification (0.69%), PDGFRA Nonsense (0.17%), and PDGFRA Codon 842 Missense (0.11%) [3].
