Daniel Lefler, MD

As a Clinical Geneticist at Penn Medicine, my goal is to provide diagnostic workup and medical management for any patient with a genetic or inherited condition. With my training in Medical Genetics and Internal Medicine, I see both adult and pediatric patients with any suspected genetic disorder, and have a special interest and expertise in the management of patients with ciliopathy conditions (disease affecting the primary cilium). When visiting our clinic, you can expect a detailed review of your medical and family history, a thorough physical exam, excellent genetic counseling from our team of Genetic Counselors, and a clear and comprehensive plan for diagnostic workup and management.
