Juvenile glaucoma linked to the GLC1A gene on chromosome 1q in a Panamanian family.

PURPOSE: To characterize clinically and genetically autosomal dominant juvenile-onset primary open-angle glaucoma in a Panamanian family.

METHODS

Twenty members of a six-generation family underwent ophthalmologic examination and genetic screening with markers near the GLC1A gene on chromosome 1q.

RESULTS

Linkage analysis disclosed evidence linking primary open-angle glaucoma in this family to the GLC1A gene on chromosome 1q, with a maximum lod score of 3.75 for marker D1S431 at an estimated recombination fraction of 0.00.

CONCLUSIONS

This is the first report of a Panamanian family in which primary open-angle glaucoma is linked to the GLC1A gene on chromosome 1q.
