Watson syndrome is believed to be a variant of neurofibromatosis type 1. The symptoms of this condition are pulmonary valvular stenosis, cafe-au-lait spots and short stature. IQ test scores for individuals with Watson syndrome can range between 60-100. Many people with this condition also have a larger than average head size (macrocephaly) and Lisch nodules. While mutations in the NF1 gene have been found in families with Watson syndrome, the exact cause of this condition is unknown. The condition is inherited in an autosomal dominant pattern. Treatment aims at managing the specific symptoms of an individual.
