Living with Hearing loss-familial salivary gland insensitivity to aldosterone syndrome

A rare condition with hearing loss in both ears and salivary glands that don't respond to the hormone aldosterone.

Understanding Hearing loss-familial salivary gland insensitivity to aldosterone syndrome

Hearing loss-familial salivary gland insensitivity to aldosterone syndrome combines hearing loss in both ears with salivary gland insensitivity to aldosterone.

People have moderate to severe sensorineural hearing loss (from the inner ear) in both ears. The salivary glands don't respond to aldosterone, which causes low sodium in the blood (hyponatremia). It is noticed in the newborn period or infancy.

Signs & symptoms

Symptoms vary. GARD lists these among the most common:

  • Hearing loss in both ears (sensorineural)
  • Differences in the salivary glands
  • Low sodium in the blood (hyponatremia)

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.

GARD says transmission appears to be autosomal recessive, meaning a child inherits a changed copy of the gene from each parent. It does not name the gene.
