<unk>  <unk> , known also as de Morsier syndrome, is a rare congenital malformation syndrome that features a combination of the underdevelopment of the optic nerve, pituitary gland dysfunction, and absence of the<unk> m pellucidum (a midline part of the brain). Two or more of these features need to be present for a clinical diagnosis — only 30% of patients have all three. French-Swiss doctor Georges de Morsier first recognized the relation of a rudimentary or absent<unk> m pellucidum with hypoplasia of the optic nerves and chiasm in 1956.
