  • Biography

    Lawrence Merritt, II, MD, is attending physician at Seattle Childrens Hospital and associate professor in the Department of Pediatrics at the University of Washington School of Medicine. He joined Childrens after completing his pediatric residency, medical genetics residency and biochemical genetics fellowship at the Mayo Clinic in Rochester, MN.


    He provides inpatient and outpatient clinical services in biochemical genetics at Children's hospital campus in Seattle and Bellevue clinics and at the Spokane newborn screening outreach clinic.  His clinical interests include long-term follow up of infants with abnormal newborn screens, urea cycle disorders and fatty acid oxidation disorders.  His clinical work has led efforts to further understand how we can better promote educational efforts and improve the quality of our follow-up of these infants.  He is the site principle investigator for the Urea Cycle Disorders Consortium Longitudinal study and received a grant to study the effects of newborn screening in patients and families with urea cycle disorders.  He is involved with development of novel pharmaceutical therapies for treatment of urea cycle disorders, fatty acid oxidation disorders, organic acidemias, glycogen storage diseases and lysosomal storage diseases.  The expansion of newborn screening the the past two decades has driven much of his clinical work.  He serves as the Program Director for the Medical Biochemical Genetics Fellowship program here at the University of Washington.
