Abstract

Primary congenital glaucoma (PCG) is the most common childhood glaucoma affecting children from birth to age 3 years and is a major cause of blindness in this young population.

Mutations in the CYP1B1 gene, associated with GLC3 locus, have been found to cause PCG in children worldwide and are the dominant genetic cause for pediatric glaucoma in the Middle East and Central Europe. Our study in a small number of Indonesian and European PCG families supports the previous studies that reported mutations of the CYP1B1 gene being responsible for the PCG phenotype. A different pattern of CYP1B1 disease-causing mutations and benign variants appears to exist in Indonesian patients when compared to patients from other ethnic backgrounds.

Other genes such as LTBP2 and PXDN gene have been reported recently by several studies as being associated with pediatric glaucoma.

The exact mechanisms of how these gene abnormalities actually cause primary congenital glaucoma remain unclear. However, with the promising research progress so far, it is hoped that we will understand more about the pathogenesis of this disease and eventually potential new molecular targets to treat this threatening blindness disease in children will be developed in the near future.
