What is the life expectancy of someone with familial dysautonomia?

Some people with FD have been known to survive well into their 70s.

What Causes Familial Dysautonomia?

Familial dysautonomia is an inherited disorder that affects one in every 3,700 people of Ashkenazi Jewish ancestry.

The deficiency is due to a mutation of theELP1gene which regulates the production of ELP1.

Familial dysautonomia is inherited in anautosomal recessivepattern.

The blood test can definitively diagnose familial dysautonomia based on two copies of theELP1gene mutation.

Preconception screening is also possible for couples at risk of having a child with FD.
