WebTest Usage. PDGFRA gene mutations occur in approximately 30% of gastrointestinal stromal tumors (GISTs) that are wild type for KIT mutation, and in 7% of GISTs overall. PDGFRA and KIT mutations are mutually exclusive in GISTs. The vast majority of PDGFRA gene mutations involve exons 12 and 18, and invariably result in constitutive … WebMutation analysis should be performed using an appropriate, validated, technique, and performed by specifically trained personnel and results should always specify the …
WebMutational analysis of GIST-mutated genes such as PDGFRA is paramount for selection of appropriate therapy for GIST (see below) but may also help confirm the diagnosis of suspect GIST that do not exhibit positive immunoreactivity for CD117/DOG1 [23].
