Disease at a Glance

Summary
Limb-girdle muscular dystrophy type 2I (LGMD2I) is a form of limb-girdle muscular dystrophy, which refers to a group of conditions that cause weakness and wasting of the muscles in the arms and legs. The proximal muscles (those closest to the body such as the upper arms and thighs) are generally most affected by the condition. In LGMD2I, specifically, signs and symptoms often develop in late childhood (average age 11.5 years) and may include difficulty running and walking. The symptoms gradually worsen overtime and affected people generally rely on a wheelchair for mobility approximately 23-26 years after onset. LGMD2I is caused by changes in the FKRP gene and is inherited in an autosomal recessive manner.

Musculoskeletal System

Musculoskeletal System

The musculoskeletal system is made up of the bones, muscles, and joints. Common symptoms of problems in the musculoskeletal system include pain, weakness, stiffness, noises in the joints, inflammation, and decreased range of motion. Diseases affecting the musculoskeletal system may be diagnosed and treated by an orthopedist, rheumatologist, or neuromuscular specialist.

Causes

Genetic Disease

Limb-girdle muscular dystrophy type 2I is a genetic disease, which means that it is caused by one or more genes not working correctly.

Disease-causing variants, or differences, in the following gene(s) are known to cause this disease: FKRP

What Is a Gene?

Inheritance

All individuals inherit two copies of most genes. The number of copies of a gene that need to have a disease-causing variant affects the way a disease is inherited. This disease is inherited in the following pattern(s):

Autosomal Recessive Inheritance

Advocacy and Support Groups

How Can Patient Organizations Help?

Patient organizations can help patients and families connect. They build public awareness of the disease and are a driving force behind research to improve patients' lives. They may offer online and in-person resources to help people live well with their disease. Many collaborate with medical experts and researchers.

Services of patient organizations differ, but may include:

  • Ways to connect to others and share personal stories
  • Easy-to-read information
  • Up-to-date treatment and research information
  • Patient registries
  • Lists of specialists or specialty centers
  • Financial aid and travel resources

Participating in Clinical Studies

Clinical studies are part of clinical research and at the heart of all medical advances, including rare diseases. Participating in research helps researchers ultimately uncover better ways to treat, prevent, diagnose, and understand human diseases.

What Are Clinical Studies?

  1. Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
  2. Observational studies involve recording changes over time among a specific group of people in their natural settings.
Learn more about the different types of clinical studies, consent forms, questions you should ask before participating in clinical studies, and the difference between research and medical treatment.

Why Participate in Clinical Studies?

How Do You Find the Right Clinical Study?

  • Use ClincalTrials.gov button below to search for studies by disease, terms, or country.
  • Consult doctors, other trusted medical professionals, and patient organizations.
  • Enroll in databases to allow researchers from participating institutions to find you.
