Living with Congenital anosmia

A condition in which a person is born unable to smell, either alone or as part of another genetic condition.

Understanding Congenital anosmia

Congenital anosmia is a condition in which people are born with a lifelong inability to smell.

It may occur alone or with a genetic disorder such as Kallmann syndrome or congenital insensitivity to pain. When it occurs alone, there is usually no family history, though some families have been reported. In most isolated cases, the genetic cause is unknown.

Signs & symptoms

GARD doesn't list specific symptoms for this condition beyond the inability to smell.

  • Lifelong inability to smell

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.
