Etimology.
This disorder was discovered in the early fall of 1970, in Montreal, Canada, when "Fitch et al." described a patient with a type of bird-headed dwarfism, he described the symptoms mentioned above, some of the symptoms suggested a diagnosis of either Werner syndrome, Seckel syndrome, Hallermann-Streiff syndrome, or Noonan syndrome. However, the authors thought there were differences that distinguished this particular case from any other syndrome, suggesting it to be separated into an entity of its own (which it did). No more cases of this disorder have been reported since then (1970).
