This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This protocol is designed to continue our research to understand the pathophysiology of congenital disorders of eye and lid movement by elucidating the genetic causes of strabismus and ptosis. The objectives of our research are to 1) identify genetic loci and gene mutations responsible for forms of human congenital strabismus and ptosis, 2) correlate thes genetic loci and specific mutations with clinical phenotypes, 3) correlate these mutations with specific anatomic changes in the brainstem and/or extraocular muscle of affected participants, 4) determine the role of each mutated gene in normal and abnormal development.
