Watson syndrome is an autosomal dominant condition characterized by Lisch nodules of the ocular iris, axillary/inguinal freckling, pulmonary valvular stenosis, relative macrocephaly, short stature, and neurofibromas.^[1]

Watson syndrome is allelic to NF1, the same gene associated with neurofibromatosis type 1.^[2]
