Primary congenital glaucoma (gene symbol: GLC3) is characterized by an improper development of the aqueous outflow system. The reduced outflow of fluid results in an increased intraocular pressure leading to buphthalmos, optic nerve damage, and eventual visual impairment. GLC3 is a heterogeneous condition with an estimated incidence of 1:2,500 in Middle Eastern and 1:10,000 in Western countries. In many families, GLC3 is an autosomal recessive trait with presentation of an earlier age-of-onset, high intraocular pressure, enlarged cloudy cornea, buphthalmos, and a more aggressive course. The pathogenesis of GLC3 remains elusive despite extensive histologic efforts to identify a single anatomic defect. Recent advances in positional mapping and cloning of human disorders provided an opportunity to identify chromosome locations of the GLC3 phenotype. Our laboratory is currently involved in the mapping of this condition by using a combination of candidate chromosome regions associated with the GLC3 phenotype and by a general positional mapping strategy. 16 refs., 3 tabs.
