Drug Sensitivity Data Categorized by Their Corresponding Mechanisms

Unusual Activation of Pro-survival Pathway (UAPP)

Key Molecule: Platelet-derived growth factor receptor alpha (PDGFRA) [1]

• Molecule Alteration: Missense mutation; p.D842V (c.2525A>T)
• Sensitive Disease: Solid tumour/cancer [ICD-11: 2A00-2F9Z]
