Living with Autosomal dominant limb-girdle muscular dystrophy type 1H

An inherited muscle condition with slowly worsening weakness that begins in the legs and later reaches the arms.

Understanding Autosomal dominant limb-girdle muscular dystrophy type 1H

Limb-girdle muscular dystrophy type 1H (LGMD1H) is an inherited muscle condition with slowly worsening weakness near the center of the body.

Weakness starts in the lower limbs and later reaches the upper limbs, with thinning of the hip and shoulder muscles, reduced reflexes, and enlarged calves. Creatine kinase, a muscle enzyme, is raised. The muscles of the face, eyes, throat, and heart are not involved.

Signs & symptoms

GARD lists these among the less common symptoms:

  • Slowly worsening weakness near the center of the body
  • Thinning of hip and shoulder muscles
  • Enlarged calf muscles
  • Reduced reflexes
  • Raised creatine kinase on blood tests

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Muscular Dystrophy Association and The Speak Foundation may keep lists of experts for this condition.

InheritanceAutosomal Dominant

GARD says this condition is inherited in an autosomal dominant way, meaning one changed copy of the gene can be enough to cause it. It doesn't list a specific gene here.
