The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
|Signs and Symptoms||Approximate number of patients (when available)|
|Abnormality of neuronal migration||90%|
|Aplasia/Hypoplasia of the cerebellum||90%|
|Skeletal muscle atrophy||90%|
|Abnormality of the vitreous humor||50%|
|Aplasia/Hypoplasia affecting the eye||50%|
|Aplasia/Hypoplasia of the corpus callosum||50%|
|Hypoplasia of penis||50%|
|Opacification of the corneal stroma||50%|
|Abnormality of the pinna||7.5%|
|Abnormality of the upper urinary tract||7.5%|
|Low-set, posteriorly rotated ears||7.5%|
|Non-midline cleft lip||7.5%|

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.
Congenital Muscular Dystrophy: From Clinical Pathology to Underlying Scientific Mechanisms, Exploring the Role of the Myomatrix
Sunday, April 22, 2012 -
Tuesday, April 24, 2012
Location: University of Nevada School of Medicine, Center for Molecular Medicine, Reno, NV
Description: The goals of the conference are to: 1) Establish the current state of knowledge in different myomatrix research areas germane to the CMDs and to dystrophic pathology, 2) Explore novel mechanisms, intersections and crosstalk of relevant mechanisms and perform comparative analysis across disease models, 3) Design effective strategies and platforms to pursue treatment development for key aspects of CMD clinical pathology to drive future translational opportunities
