Living with Autosomal recessive limb-girdle muscular dystrophy type 2C

An inherited muscle condition with weakness around the hips and shoulders that starts in childhood.

Understanding Autosomal recessive limb-girdle muscular dystrophy type 2C

Autosomal recessive limb-girdle muscular dystrophy type 2C (LGMD2C) is a genetic muscle condition that affects the muscles around the hips and shoulders.

It causes slowly worsening loss of muscle bulk and weakness on both sides of the body. It begins in childhood. Some people have enlarged calf muscles and tongue, heart muscle disease (cardiomyopathy), or breathing problems.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Weakness in the arm muscles
  • Trouble running and climbing stairs
  • Frequent falls
  • Waddling walk
  • Enlarged calf muscles and tongue
  • Winged shoulder blades (scapular winging)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists, genetic specialists and heart and blood vessel specialists.

  3. Consider genetic testing

    Changes in SGCG are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Muscular Dystrophy Association, The Speak Foundation and Children's Cardiomyopathy Foundation may keep lists of experts for this condition.

InheritanceAutosomal Recessive
GenesSGCG

It is caused by changes in the SGCG gene. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
