Katherine Rauen, M.D., Ph.D., M.S.

Medical geneticist

Dr. Katherine Rauen is a medical geneticist and director of the NF/Ras Pathway Genetics Clinic, which she founded in 2007. She is a leader in studying Ras/MAPK pathway genetics syndromes and coined the term "RASopathies." Ras/MAPK is the regulation of cell growth, critical to normal development.

Rauen is internationally known for her pioneering work in array comparative genomic hybridization (CGH), a technique to analyze genes. She studies cancer syndromes to identify underlying genetic abnormalities and cancer "pathways." She led a research team that discovered the genetic cause of cardio-facio-cutaneous syndrome (CSFC), a condition that affects many parts of the body, particularly the heart, facial features, and skin and hair. She serves on the medical advisory board of CFC International and is a co-director of the Costello Syndrome Family Network. Rauen earned a master's degree in Human Physiology and a doctorate in Genetics at the University of California, Davis. She earned a medical degree at the University of California, Irvine, and completed residency training in Pediatrics and a fellowship in Medical Genetics at UCSF. She is a UCSF associate professor in Medical Genetics in Pediatrics as well as in Obstetrics, Gynecology and Reproductive Sciences. She is associate director of the UCSF Medical Genetics Residency Program.
