Learn About Familial Dysautonomia

What is the definition of Familial Dysautonomia?

Familial dysautonomia (FD) is an inherited disorder that affects nerves throughout the body.

What are the alternative names for Familial Dysautonomia?

Riley-Day syndrome; FD; Hereditary sensory and autonomic neuropathy - type III (HSAN III); Autonomic crises - familial dysautonomia

What are the causes of Familial Dysautonomia?

FD is passed down through families (inherited). A person must inherit a copy of the variant gene from each parent to develop the condition.

FD occurs most often in people of Eastern European Jewish ancestry (Ashkenazi Jews). It is caused by a change to a gene. It is rare in the general population.

What are the symptoms of Familial Dysautonomia?

FD affects the nerves in the autonomic (involuntary) nervous system. These nerves manage daily body functions such as blood pressure, heart rate, sweating, bowel and bladder emptying, digestion, and the senses.

Symptoms of FD are present at birth and may grow worse over time. Symptoms vary, and may include:

  • Swallowing problems in infants, resulting in aspiration pneumonia or poor growth
  • Breath-holding spells, resulting in fainting
  • Constipation or diarrhea
  • Inability to feel pain and changes in temperature (can lead to injuries)
  • Dry eyes and lack of tears when crying
  • Poor coordination and unsteady walk
  • Seizures
  • Unusually smooth, pale tongue surface and lack of taste buds and decrease in sense of taste

After age 3, most children develop autonomic crises. These are episodes of vomiting with very high blood pressure, racing heart, fever, and sweating.

What are the current treatments for Familial Dysautonomia?

FD can't be cured. Treatment is aimed at managing the symptoms and may include:

  • Medicines to help prevent seizures
  • Feeding in an upright position and giving textured formula to prevent gastroesophageal reflux (stomach acid and food coming back up, also called GERD)
  • Measures to prevent low blood pressure when standing, such as increasing intake of fluid, salt, and caffeine, and wearing elastic stockings
  • Medicines to control vomiting
  • Medicines to prevent dry eyes
  • Physical therapy of the chest
  • Measures to protect against injury
  • Providing enough nutrition and fluids
  • Surgery or spinal fusion to treat spine problems
  • Treating aspiration pneumonia

When should I contact a medical professional for Familial Dysautonomia?

Contact your provider if symptoms change or get worse. A genetic counselor can help teach you about the condition and direct you to support groups in your area.

How do I prevent Familial Dysautonomia?

Genetic DNA testing is very accurate for FD. It may be used for diagnosing people with the condition or those who carry the gene. It can also be used for prenatal diagnosis.

People of Eastern European Jewish background and families with a history of FD may wish to seek genetic counseling if they are thinking of having children.
