Learn About Familial Dysautonomia
Familial dysautonomia (FD) is an inherited disorder that affects nerves throughout the body.
Riley-Day syndrome; FD; Hereditary sensory and autonomic neuropathy - type III (HSAN III); Autonomic crises - 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.
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.
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

Advances in diagnosis and treatment are increasing the survival rate. About one half of babies born with FD will live to age 30.
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.
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.
Summary: This goal of this observational study is to clarify the variations in the natural course of atypical parkinsonian syndromes (APS, including MSA, DLB, PSP, and CBD), such as the progression rate of motor and non-motor symptoms and characteristic imaging evolution patterns. Establish a comprehensive assessment framework for APS, and develop clinical and biological databases to identify biomarkers wi...
Summary: Postural orthostatic tachycardia syndrome (POTS) is a disorder of unknown origin characterized by orthostatic intolerance and increased heart rate (HR) of ≥ 30 beats/minute during orthostasis in the absence of orthostatic hypotension. In addition to the orthostatic intolerance and tachycardia, patients with POTS experience several debilitating symptoms including light-headedness, nausea, blurred v...
