IN THIS ISSUE of the ARCHIVES, Alward and coworkers1
describe the prevalence of "plausible disease causing-sequence variations
(DCVs) in the MYOC [myocilin] gene" among a large
unselected group of consecutive patients with a variety of open-angle glaucomas
in a tertiary glaucoma practice. Their finding that DCVs occur in approximately
3% and 6% of patients with adult-onset primary open-angle glaucoma (POAG)
and with juvenile open-angle glaucoma (JOAG), respectively, confirms findings
from earlier reports.2-4
None of the normal subjects exhibited DCVs in the myocilin coding sequence.
If a new commercially available product, the OcuGene Test (Insite Vision,
Alameda, Calif) had been used to screen this population, none of the 13 patients
with adult-onset POAG with DCVs would have been detected. The OcuGene test
also determines the presence of a polymorphism in the promoter region of the
myocilin gene (MYOC.mt1) that has recently been described by Colomb and colleagues5 as being an indicator . . . [Full Text of this Article]
