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

An inherited muscle condition that affects the shoulder and pelvic muscles, starting in childhood.

Understanding Autosomal recessive limb-girdle muscular dystrophy type 2F

Autosomal recessive limb-girdle muscular dystrophy type 2F, also called delta-sarcoglycan-related LGMD R6, affects the muscles in the shoulder and pelvic area.

It starts in childhood. Symptoms vary and can include muscle weakness and wasting, breathing difficulty, and heart problems. Some people have enlarged calf muscles, cramps, and high creatine kinase levels in the blood. People typically have normal development and thinking.

Signs & symptoms

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

  • Muscle wasting in the shoulders and arms
  • Wasting of the thigh muscles
  • Winged shoulder blades (scapular winging)
  • Shuffling walk
  • Enlarged calf muscles (from summary)
  • Muscle cramps (from summary)

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 SGCD 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.

GenesSGCD

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