Living with Familial cutaneous telangiectasia and oropharyngeal predisposition cancer syndrome

A rare inherited condition with small widened skin blood vessels, nail and tooth changes, and a higher risk of mouth and throat cancer.

Understanding Familial cutaneous telangiectasia and oropharyngeal predisposition cancer syndrome

Familial cutaneous telangiectasia and oropharyngeal predisposition cancer syndrome is a rare inherited syndrome that raises cancer risk.

It starts in newborns and infants. Features include tiny widened blood vessels on the skin (telangiectasia), mild tooth and nail differences, and patchy hair loss over affected skin. People have a higher lifetime risk of cancer of the mouth and throat. Other cancers have also been reported.

Signs & symptoms

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

  • Tiny widened blood vessels on the face (telangiectasia)
  • Dental cavities
  • Grooved nails
  • Sparse outer eyebrows
  • Cancer of the mouth and throat (oropharyngeal)

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

  3. Consider genetic testing

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