Living with Terminal osseous dysplasia-pigmentary defects syndrome

A genetic condition that affects the bones of the hands and feet and causes skin color spots on the face and scalp.

Understanding Terminal osseous dysplasia-pigmentary defects syndrome

Terminal osseous dysplasia-pigmentary defects syndrome is a genetic condition with hand and foot differences, skin spots, and small skin growths on the fingers or toes.

People with this condition have differently shaped hands and feet, darker patches or bumps on the skin of the face and scalp, and growths of fibrous tissue on the fingers or toes (digital fibromatosis). Signs usually appear in the newborn period or infancy.

Signs & symptoms

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

  • Short fingers or toes (brachydactyly)
  • Fingers that curve permanently (clinodactyly)
  • Joints that cannot fully straighten (flexion contracture)
  • Darker raised skin spots (hyperpigmented papules)
  • Hair loss (alopecia)
  • Fibrous growths on the fingers or toes (digital fibromatosis)

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, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

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