Living with Nebulin-related early-onset distal myopathy

A rare inherited muscle condition with slowly worsening weakness in the lower legs, fingers, and neck, starting early in life.

Understanding Nebulin-related early-onset distal myopathy

Nebulin-related early-onset distal myopathy is a rare inherited muscle condition with slowly worsening weakness, mostly in the hands and feet.

Weakness and wasting start early and mainly affect the muscles that lift the foot and extend the fingers, as well as the muscles that bend the neck. It is slowly progressive. A muscle biopsy does not always show nemaline rods.

Signs & symptoms

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

  • Foot drop
  • Weakness in the muscles that extend the fingers
  • Weakness in the hand muscles
  • Weakness in the muscles that bend the neck
  • Tight ankles (flexion contracture)
  • High palate

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 and genetic specialists.

  3. Consider genetic testing

    Changes in NEB 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 may keep lists of experts for this condition.
