SUMMARY/ABSTRACT
Familial dysautonomia (FD) is a severe neurodegenerative disorder caused by a splice site mutation in intron 20
of the elongator acetyltransferase complex subunit 1 (ELP1). Despite its complex neurological phenotype, FD
patients suffer from progressive blindness that severely affects their quality of life. Patients with FD show a…
