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

An inherited muscle condition with slowly worsening weakness, stiff joints, and a stiff spine, starting in childhood or the teens.

Understanding Autosomal recessive limb-girdle muscular dystrophy type 2Y

Autosomal recessive limb-girdle muscular dystrophy type 2Y is an inherited muscle condition with slowly worsening weakness that starts in the first or second decade of life.

Weakness and wasting affect muscles both near and far from the center of the body. People can also have stiff finger joints, a rigid spine, reduced lung function, and mild heart muscle disease.

Signs & symptoms

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

  • Muscle weakness, including in the hands and feet
  • Trouble climbing stairs
  • Stiff or bent finger joints
  • Tight ankle joints
  • Rigid spine
  • Extra heartbeats (premature ventricular contractions)

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 TOR1AIP1 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

    The Speak Foundation may keep lists of experts for this condition.

Quick facts

Symptoms usually startChild and as a Teenager
InheritanceAutosomal Recessive
GenesTOR1AIP1

It is caused by changes in the TOR1AIP1 gene. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
