Familial Dysautonomia, also called FD, is a neurologic disorder characterized by episodic vomiting, abnormal sweating, pain and temperature insensitivity, an inability to produce tears, scoliosis, and abnormal feeding and sucking difficulties. This disease is found almost exclusively in Ashkenazi Jewish families.
1 in every 36 Ashkenazi Jews is a carrier of FD – and the disease is almost exclusively found in Ashkenazi Jewish families.
When two carriers have a child together, there is a 1 in 4 chance the child will have Familial Dysautonomia. (See autosomal recessive inheritance )
Genetic testing, also called “carrier screening”, is available to determine if you are a carrier of FD. This test has a detection rate of 99%.
A single mutation on the IKBKAP gene on chromosome 9 accounts for most cases of FD.
The only treatments available for FD treat the symptoms of the disease. Though the treatments cannot cure FD, they can improve the length and quality of a patient’s life.
