Familial dysautonomia (FD) is the best-known and most common member of a group of congenital sensory/autonomic neuropathies characterized by widespread sensory and variable autonomic dysfunction. As opposed to the sensory/motor neuropathies, little is known about the causes of neuronal dysfunction and loss in the sensory/autonomic neuropathies. FD involves progressive neuronal degeneration, has a broad impact on the operation of many of the body’s systems, and leads to a markedly reduced quality of life and premature death. In 2001, we identified two mutations in the IKBKAP gene that result in FD. IKBKAP encodes IKAP, a member of the putative human holo-Elongator complex, which may facilitate transcription by RNA polymerase II. Whether or not the Elongator plays this role is moot. The FD mutation found on >99.5% of FD chromosomes does not cause complete loss of function. Instead, it results in a tissue-specific decrease in splicing efficiency of the IKBKAP transcript; cells from patien
