Human narcolepsy is associated with undetectable hypocretin-1 levels in the cerebrospinal fluid. First publication implicating the hypocretin system in human narcolepsy, published in The Lancet, January 1st 2000.
Peyron C, Faraco J, Rogers W, Ripley B, Overeem S, Charnay Y, Nevsimalova S, Aldrich M, Reynolds D, Albin R, Li R, Hungs M, Pedrazzoli M, Padigaru M, Kucherlapati M, Fan J, Maki R, Lammers GJ, Bouras C, Kucherlapati R, Nishino S, Mignot E. A mutation in a case of early onset narcolepsy and a generalized absence of hypocretin peptides in human narcoleptic brains. Nat Med. 2000 Sep;6(9):991-7.
Most cases of human narcolepsy cases are not caused by hypocretin gene mutations. Only one hypocretin mutation was found, in a case with unsually early narcolepsy onset at 6 months of age. This finding demonstrates that hypocretin mutations can cause narcolepsy in humans as they do in animals.
This manuscript also extends on the human CSF study by showing that human narcolepsy brain tissues have no hypocretin-1 and 2 peptides. It also reports that human narcolepsy cases have no preprohypocretin transcripts in their hypothalami, an area containing the hypocretin cells. First publication indicating that human narcolepsy is caused by a destruction of hypocretin-containing cells, published in Nature Medicine, September 1st 2000.
