 Genetic research in this area has been largely centered on variations of the BRCA1/BRCA2 mutations, as well as how genetics affect decision, health behaviors, and outcomes for patients.Chung's research within the Columbia pancreas cancer genetic program discovered 27% of patients from the program had identifiable genetic causes for their pancreatic cancer.Chung's research on neurodevelopment disorders at Columbia has resulted in the identification of novel genes associated with neurodevelopment disabilities and autism, including KAT6A, PPP2R5D, PRUNE, EMC1, AHDC1, POGZ, PURA, ARID2, DDX3X, SETD2, and SPATA5.
