Overview

Dr. Charlotte Sumner is a Professor of Neurology and Neuroscience at Johns Hopkins University School of Medicine. Dr. Sumner cares for patients with genetically-mediated neuromuscular diseases. Her practice is notable for a focus on individuals with inherited neuromuscular disorders of peripheral nerves and motor neurons, including spinal muscular atrophy (SMA) and Charcot-Marie-Tooth (CMT) disease. She co-directs the Johns Hopkins Muscular Dystrophy Association Care Center, the Spinal Muscular Atrophy (SMA), and the Charcot-Marie-Tooth (CMT) clinics, which deliver multidisciplinary clinical care, engage in international natural history studies, and provide cutting edge therapeutics. Dr. Sumner’s research focuses on developing treatments for degenerative disorders of motor neurons and peripheral nerves. Her laboratory uses human tissues and induced pluripotent cell lines, mouse models and cultured cells to characterize disease mechanisms and develop treatments. Dr. Charlotte Sumner received her medical degree from the University of Pennsylvania School of Medicine following undergraduate studies at Princeton University. She completed internal medicine internship and neurology residency at the University of California San Francisco, after which she returned to the east coast for a neuromuscular fellowship at Johns Hopkins and a neurogenetics fellowship in the Neurogenetics Branch at the National Institute of Neurological Disorders and Stroke. She joined the neurology faculty at Johns Hopkins in 2006.

Dr. Sumner is rated as an Advanced provider by MediFind in the treatment of Septic Arthritis. Her top areas of expertise are Spinal Muscular Atrophy (SMA), Charcot-Marie-Tooth Disease, Primary Lateral Sclerosis, Spinal Muscular Atrophy Type 2, and Gastrostomy.

Her clinical research consists of co-authoring 93 peer reviewed articles and participating in 2 clinical trials. MediFind looks at clinical research from the past 15 years.

Dr. Bipasha Mukherjee-Clavin is an Assistant Professor of Neurology in the Johns Hopkins University School of Medicine. She cares for patients with neuromuscular disorders, with a special focus on patients with peripheral neuropathy, immune-mediated neuropathy, and inherited neuropathy (also known as Charcot-Marie-Tooth disease). She sees patients in the Johns Hopkins Peripheral Nerve and multidisciplinary Charcot-Marie-Tooth clinics, and performs electromyography in the Johns Hopkins EMG lab. As a stem cell biology-trained scientist, Dr. Mukherjee-Clavin's research is focused on the use of patient-derived induced pluripotent stem cells to model genetic Schwann cell and peripheral nerve disorders to undercover novel pathways and potential treatments. During her PhD she published one of the first studies of CMT1A using patient derived stem cells (Comparison of three congruent patient-specific cells types for the modelling of a human genetic Schwann-cell disorder. Nature Biomedical Engineering. volume 3, pages 571–582 (2019)). In 2022, she was awarded the Passano award, given to a promising early career physician-scientist in the Johns Hopkins University School of Medicine. Dr. Mukherjee-Clavin completed her undergraduate studies at the University of California, Berkeley. She then completed her MD/PhD degrees, Neurology residency, and clinical Neuromuscular fellowship in the Johns Hopkins University School of Medicine. She joined the Johns Hopkins Neurology faculty in 2022. Dr. Mukherjee is rated as an Experienced provider by MediFind in the treatment of Septic Arthritis. Her top areas of expertise are Charcot-Marie-Tooth Disease, Guillain-Barre Syndrome, Chronic Polyradiculoneuritis, and Miller-Fisher Syndrome.
