Clinical Interests

Dr. Raun is the attending for both the Biochemical Genetics and Dysmorphology services for UC Davis Health and also supervises medical genetics fellows, rotation residents and medical students. In addition, Dr. Rauen covers consult servicesfor Mercy San Juan and Methodist hospitals while on service and also attends at UC Davis MIND Institute Massie Family Clinic.

Dr. Rauen launched the UC Davis NF/Ras Pathway Clinic to provide a multidisciplinary approach to the diagnosis and care of individuals with RASopathies [Neurofibromatosis types 1 and 2, Noonan/LEOPARD, CFC, Costello, Legius syndromes and others], or individuals with a phenotype which is suggestive of a diagnosis in this pathway.
