Diseases Studied
The Rare Diseases Clinical Research Network is an NIH-funded research network of 20 active consortia or research groups working to advance treatment for diseases that are rare. Use the search tools on this page to find the diseases we currently study. You can reach out to the indicated consortia or research groups for more information on those diseases and studies underway.
This network focuses on clinical research and does not generally support clinical care outside of research activities. To learn about other rare diseases, please visit the Genetic and Rare Diseases Information Center (GARD), which is an NIH program that helps the public find reliable information about rare and genetic diseases. Their staff are specialists. Contact them at 1-888-205-2311 or email GARDinfo@nih.gov.

Other unknown Charcot Marie tooth (CMT) peripheral neuropathy
Disease Category: Inherited Neuropathies
A rare disorder in which the cause of the disease is unknown. It is either inherited (passed on to a child from one or both parents) or sporadic (occurring spontaneously in an individual over time). The hallmark characteristic is damage to nerve axons (nerve ends) or myelin (fatty coating around nerves) in the extremities. Symptoms include lower leg muscle weakness, sensory loss, and atrophy (wasting); balance problems; hyporeflexia (decreased reflexes); lack of proprioception (spatial awareness of the limbs); and foot deformities requiring ankle braces to support walking.

6601: Natural History Evaluation of Charcot Marie Tooth Disease
A lack of high quality natural history data, based on a uniform, quantitative evaluation of patients continues to hinder the efforts to perform clinical trials for most forms of CMT. This study aims to determine the natural history of CMT1B, CMT2A, CMT4A, CMT4C, and other types of CMT in order to refine the overall picture of disease for use in future clinical trials.
6602: Genetics of CMT- Modifiers of CMT1A, New Causes of CMT
Despite great success of gene identification in CMT, there is still much more genetic heterogeneity to uncover. In addition, modifying factors are an important aspect of CMT, but have been rarely studied in a systematic fashion. This study will apply innovative study designs and the latest technology to tackle some of the most pressing genetic issues in CMT, ultimately paving the way for new therapeutic approaches. This study aims to determine if gene modifiers exist for CMT1A, and to find new genetic causes of CMT.
6603: Development of CMT Peds Scale for Children with CMT
It is likely that progression also varies during different pediatric age groups for different forms of CMT. However, there are no large-scale epidemiological data available for the genetic distribution or natural history of inherited neuropathies in the pediatric age group. This study aims to develop and test the CMT Peds scale (CMTPedS) in children with CMT in order to refine the scoring for future natural history and therapeutic trials. This study involves designing a pediatric scale(s) to measure impairment in children with CMT and to test the scale’s ability to measure disease progression in patients.
6611: Charcot-Marie-Tooth disease Infant Scale
No CMT-specific clinical outcome measure currently exists to measure disease severity or progression in children from birth to 3 years of age. This is an important omission since future clinical interventions may be most effective in slowing disease progression if given early in life.The purpose of this study is to develop and validate a clinical outcome measure to evaluate disability and disease progression of children ≤3 years of age (infants and toddlers) with various types of Charcot-Marie-Tooth disease (CMT).
