Familial dysautonomia (FD) is a progressive degenerative disorder affecting the autonomic and sensory nervous systems. Some common features of FD include a decreased ability to feel pain or temperature sensations, blood pressure and body temperature fluctuations, difficulties feeding and swallowing, gastrointestinal motility problems, developmental delay, recurrent pneumonias and decreased stature. FD is an AR disorder caused by a mutation in the IKBKAP gene, located on chromosome 9 (9q31). Two mutations in the IKBKAP gene account for over 99% of the mutations seen in AJ individuals affected with FD.
