Watson syndrome

An atypical form of neurofibromatosis type I (OMIM:193520) which is characterised by the presence of pulmonary stenosis, cafe-au-lait spots and mental retardation.

Molecular pathology
Defects in NF1, which encodes neurofibromin 1 (a protein that stimulates RAS’s GTPase activity), cause Watson syndrome.
