Horner syndrome is caused by damage to a certain pathway in the sympathetic nervous system. The sympathetic nervous system regulates heart rate, pupil size, perspiration, blood pressure and other functions that enable you to respond quickly to changes in your environment.
Pfeiffer syndrome is caused by a specific mutation (change) in a gene called fibroblast growth factor receptor (FGFR 1 or FGFR2). This gene is also involved in other craniofacial anomalies such as Crouzon syndrome and Apert syndrome. Experts do not know the exact cause of these gene mutations.
