Living with Thickened earlobes-conductive deafness syndrome

A genetic condition with small, thick ears, a small lower jaw, and hearing loss from ear bone differences.

Understanding Thickened earlobes-conductive deafness syndrome

Thickened earlobes-conductive deafness syndrome is a genetic condition with small ears, thick earlobes, a small lower jaw, and hearing loss.

The hearing loss is conductive, which means sound does not pass well through the middle ear. It is due to differences in the tiny ear bones (ossicles) present from birth. The condition is autosomal dominant. Signs may be noticed at any time in life.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet, but the summary describes these features:

  • Small ears (microtia)
  • Thick earlobes
  • Small lower jaw (micrognathia)
  • Hearing loss from ear bone differences (conductive hearing loss)

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.

Quick facts

InheritanceAutosomal Dominant

GARD says changes in genes (variants) cause this condition and that it is autosomal dominant, so one changed copy of a gene can be enough. It doesn't name a specific gene.
