Philosophy of Care

Dr. Rauen is committed to academic medicine, medical education, and advancing best practices for patients with RASopathies. She is the innovator of the world-renowned NF/Ras Pathway Clinic which she initiated in 2007 and this clinic has now been emulated around the globe. She Chairs the annual UC Davis Human Genomics Symposium and the UC Davis Human Genomics Seminar Series. She serves on the medical advisory board of CFC International, is a Co-Director for the Costello Syndrome Family Network, and serves on the advocacy advisory broad for RASopathies Network USA and Global Genes.

Research/Academic Interests

Dr. Rauen is internationally known for her pioneering work in the early application of microarray technology in clinical genetics and as a leader and major contributor to the understanding of the “RASopathies”, a termed she coined to describe the genetic syndromes of the RAS/MAPK pathway. Her research program involves the clinical translational study of cancer syndromes with effort to identify underlying genetic abnormalities affecting common developmental and cancer pathways. Dr. Rauen led the research team, including the CFC International Family Support Group that discovered the genetic cause of cardio-facio-cutaneous syndrome (CFC) and independently identified the genetic cause of Costello syndrome (CS). Along with understanding the basic biochemical alteration of germline mutation in the genes BRAF and MEK1/2, Dr. Rauen most recently defined a novel skeletal myopathy in patients with CS and CFC. Dr. Rauen’s research addresses the cellular mechanisms that mediate myogenesis and its dysregulation using mouse models for CS and CFC.
