Pitt-Hopkins Syndrome (PTHS) is a rare disorder of severe mental retardation. Facial dysmorphism include a beaked nose, flared nostrils, and a wide mouth with a 'cupid's-bow' shaped upper lip. A particular breathing pattern is characteristic of PTHS. The defective gene is TCF4 in PTHS, and in patients who show severe mental retardation and other features resembling PTHS have mutations in CNTNAP2 and Neurexin I.

タイトル
CNTNAP2 and NRXN1 are mutated in autosomal-recessive Pitt-Hopkins-like mental retardation and determine the level of a common synaptic protein in Drosophila.
