Philosophy of Care

Rare genetic conditions have profound impacts on patients and their families. Dr. Beleford's philosophy of care is that the needs of the patient come first. Dr. Beleford strives to help patients and their families make informed medical decisions about their care, including decisions about pursuing genetic testing, based on their unique needs and desired outcomes. 

Clinical Interests

Dr. Beleford is a clinical geneticist and physician scientist who provides care for children, adults, and families with rare, complex genetic disorders including chromosome disorders, single-gene disorders, and multifactorial disorders with complex inheritance. She has a special clinical interest in vascular anomalies - conditions that cause arterial, venous, and lymphatic malformations. She is also interested in rare genetic conditions that occur in adults and in disorders of sexual development in adults.

Research/Academic Interests

Dr. Beleford's research program within the Department of Pediatrics and Department of Physiology and Membrane Biology studies the molecular genetic causes of vascular anomalies - disorders of arterial, venous, and lymphatic development. Dr. Beleford's group is interested in genetic modifiers of rare vascular conditions such as Hereditary Hemorrhagic Telangiectasia and in clarifying molecular signals and interactions that cause vascular disease. The lab utilizes mouse disease modeling and basic molecular biology techniques.
