We were interested to read the communication in your December 1966 issue from Drs. Winkelmann, Bourlond, and Smith (Pediatrics, 38:1060) in which they described normal nerve endings in a patient with familial dysautonomia. They stated that nerve conduction studies would be interesting but had not so far been done in dysautonomia.
During the last 18 months we have had the opportunity to study 13 children with this syndrome performing nerve conduction studies in 10 and, in two instances, skin biopsies.
