Genes linked to Primary open angle glaucoma
OPTN: Optineurin
It serves as an adaptor in selective autophagy, vesicle trafficking, and inflammatory signaling and helps target damaged mitochondria or protein aggregates for clearance. Pathogenic variants can cause amyotrophic lateral sclerosis or certain glaucomas depending on the mechanism.
1 disease-causing and 149 uncertain variants in OPTN are linked to Primary open angle glaucoma.
Known disease-causing variants in Primary open angle glaucoma

Frequently asked questions
Which genes are linked to Primary open angle glaucoma?
In CATVariant, Primary open angle glaucoma is linked to 1 analyzed protein: OPTN (Optineurin).
How many genetic variants are linked to Primary open angle glaucoma?
154 variants: 1 are classified as disease-causing (pathogenic or likely pathogenic) in ClinVar and 149 are of uncertain significance or have conflicting reports.
Which uncertain variants in Primary open angle glaucoma look disease-causing?
None of the uncertain variants currently reaches the likely-pathogenic range on computable evidence alone.
About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
