Living with Acroosteolysis-keloid-like lesions-premature aging syndrome

A rare genetic condition with a prematurely aged look, scar-like skin lesions, and bone changes in the hands and feet.

Understanding Acroosteolysis-keloid-like lesions-premature aging syndrome

Acroosteolysis-keloid-like lesions-premature aging syndrome is a rare genetic progeroid syndrome with a prematurely aged appearance.

It brings loss of body fat, thin, see-through skin, sparse hair, and muscle wasting. Teeth erupt late. Keloid-like lesions form where there is pressure. Bone differences include loss of bone at the fingertips, small hands and feet, curving spine, thin bones, and joints that gradually stiffen. GARD lists onset as the newborn and infant period.

Signs & symptoms

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

  • Prematurely aged appearance
  • Loss of bone at the fingertips (acroosteolysis)
  • Short palms
  • Delayed bone maturation
  • Closely set eyes
  • Cyst at the back of the brain

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 genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in PDGFRB are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Quick facts

Symptoms usually startNewborn and as an Infant
InheritanceAutosomal Dominant
GenesPDGFRB

Changes in the PDGFRB gene cause this condition. It is autosomal dominant, so one changed copy of the gene is enough.
