Glaucoma (developmental)

Gene: FOXC1

PMID: 32720677 - Ferre-Fernández et al 2020 - zebrafish knockout lines with combinations of the two orthologs of FOXC1 in zebrafish, foxc1a and foxc1b. 3 phenotypes:
1. foxc1a−/− single knockout homozygous embryos and foxc1−/− double knockout homozygous embryos - severe global vascular defects and early lethality, as well as microphthalmia, periocular edema and absence of the anterior chamber of the eye
2. fish with heterozygous loss of foxc1a combined with homozygosity for foxc1b (foxc1a+/−;foxc1b−/−) demonstrated craniofacial defects, heart anomalies and scoliosis
3. All other single and combined genotypes appeared normal.

Variants in this GENE are reported as part of current diagnostic practice

Comment on list classification: Feedback from Arianna Tucci: the phenotype includes glaucoma so suitable to add to the panel.

Comment on list classification: Enough evidence associated with the given diseases (see phenotypes), however glaucoma may not be a feature in all patients therefore unsure whether this should be green on this panel.
