Living with Intellectual disability-balding-patella luxation-acromicria syndrome

A very rare condition in males with severe intellectual disability, slipping kneecaps, small hands and feet, and early balding.

Understanding Intellectual disability-balding-patella luxation-acromicria syndrome

Intellectual disability-balding-patella luxation-acromicria syndrome is a very rare syndrome with severe intellectual disability, slipping kneecaps, and small hands and feet.

Other features are low hormone activity in the sex glands (hypogonadism) and facial differences including a flat midface and early balding at the forehead and temples. GARD says it has been described in three unrelated males. It begins in the newborn period or infancy.

Signs & symptoms

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

  • Severe intellectual disability
  • Kneecaps that slip out of place (patella luxation)
  • Small hands and feet (acromicria)
  • Low sex gland activity (hypogonadism)
  • Early balding
  • Blue eyes and a broad, bulbous nose

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 bone and joint specialists, brain and nervous system specialists and genetic specialists.

  3. Ask which tests can help

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