Congenital Muscular Dystrophy (CMD)
There are over 30 forms of CMD, each with a specific presentation, cause, and progression.

What are Titinopathies?
All forms of CMD are considered rare diseases and have significant barriers to resources, access to care, and awareness.
The resources and information compiled on this page were driven by the education provided through the coordinated efforts of the many people who organized the 2022 Scientific and Family Congenital Muscular Dystrophy Conference attended by Clover Genetics representative, Rachel Baer, Co-Founder and Director of Education. We are humbled and thankful to have had the opportunity to learn from the CMD community.
The educational presentations from both the scientific and affected patient community have been referenced along with resources from: CureCMD.org | MDA.org | raredisease.gov | FDA.gov
Congenital Muscle Disease International Registry: Leading the Way to a Treatment and Cure
One of the struggles in developing treatments for rare diseases is that there are requirements to have data from a certain number of patients to begin a safe clinical trial or even identify the best scientific technique to begin developing a targeted treatment. This is why it is critical for the future of the CMD community to ensure that as many affected patients as there are available and willing to participate are signed up for the CMD International Registry. Once registered, patients can partner with advocacy organizations, researchers, and clinicians as trials or research opportunities arise for eligible patients.

The CMD Tissue Repository: Accelerating Research for CMD
The CMD Tissue Repository collects left over muscle biopsy tissue from any surgeries or tests patients may have had. These samples allow scientists to have a greater insight about how the person’s disorder is impacting their tissue and the progression of these rare diseases.

Titinopathies:
The Titin Gene (TTN) codes for the largest protein in the human body, titin! It is critical for the function of muscles, notably the heart, and when it is altered, it can cause a variety of different disorders across a broad spectrum that have characteristic traits of muscular dystrophies, frequently with cardiac and respiratory symptoms.
These syndromes can include a number of disorders ranging in severity:
Limb-Girdle Muscular Dystrophies
Tibial Muscular Dystrophy
Heart Problems (Cardiomyopathy, arrhythmias, and more)
Multi-Minicore Disease with Heart Disease
Centronuclear Myopathy
Hereditary Myopathy with Early Respiratory Failure
Early-Onset Myopathy with Fatal Cardiomyopathy
Unspecified Muscle weakness
Childhood-Juvenille Onset; Emery-Dreifuss-Like Phenotype without cardiomyopathy
Salih Myopathy
