Living with Thong Douglas Ferrante syndrome

A very rare genetic condition with short stature, hearing loss, no speech, and repeated infections.

Understanding Thong Douglas Ferrante syndrome

Thong Douglas Ferrante syndrome is a rare genetic condition present from birth with short stature, hearing loss, and repeated infections.

People also have a lack of speech (mutism) and differences in the face. The repeated infections are linked to abnormal movement of infection-fighting white cells (neutrophils). It starts during pregnancy and is noticed at birth. GARD says there have been no further descriptions in the medical literature since 1978.

Signs & symptoms

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

  • Short stature
  • Hearing loss (sensorineural)
  • Inability to speak (mutism)
  • Early closing of skull seams (craniosynostosis)
  • Glaucoma
  • Differences in how the immune system works

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 ear, nose, and throat specialists and genetic specialists.

  3. Ask which tests can help

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