Can GDC data be used in commercial and academic tools?

GDC data available as open-access data can be used with proper accreditation. Use of controlled-access data requires dbGaP access and users must abide by the data use agreement (DUA) associated with the study. See GDC Data Access and Sharing Policies or contact the NCI Office of Data Sharing directly for further clarification: NCIOfficeofDataSharing@mail.nih.gov.
