{Abstract}: Juvenile onset open-angle glaucoma is described as a primary open-angle glaucoma, with an age of onset before 40 years. These patients have a higher prevalence of myopia.<BR>We describe the phenotype of juvenile onset open-angle glaucoma in a patient with a rare variant in EFEMP1 gene, who was also detected to have Stickler syndrome(STL).<BR>Whole exome sequencing (WES) was undertaken in 40 unrelated families where the proband had juvenile onset open-angle glaucoma (JOAG).<BR>Out of these, eight were autosomal dominant, while the rest did not have any other affected first-degree relative. Out of the 8 autosomal dominant JOAG families, MYOC mutations were detected in 3(37.5%) and LTBP2 in 1(12.5%). One family (12.5%) had a rare EFEMP1 sequence variant in both affected father and daughter. The daughter also had high myopia and a pathogenic COL11A1 sequence variant that led to a coincidental diagnosis of STL in her.<BR>This is a rare association of EFEMP1 and COL11A1 sequence variants in a JOAG patient with STL. The study also reiterates the association of JOAG with EFEMP1, which should be looked for, especially in families with autosomal dominant JOAG.
