Novel heterozygous variants in cause different anterior segment dysgenesis phenotypes in monozygotic twins.

Ophthalmic Genet 2021 May 14:1-7. Epub 2021 May 14.

Department of Ophthalmology and Vision Sciences, Hospital for Sick Children, Toronto, Ontario, Canada.

Background: Since bi-allelic variants in the gene were first discovered in 2011 to be associated with anterior segment dysgenesis, a spectrum of ophthalmologic and systemic clinical manifestations has been described. This manuscript reports two distinct clinical phenotypes in monozygotic twin sisters, including the previously unreported ocular manifestation of bilateral primary aphakia, associated with novel compound heterozygous variants in the gene.

Materials And Methods: We used genome sequencing to study a non-consanguineous family with monozygotic twin sister probands: one presenting with bilateral microphthalmia, primary aphakia, total corneal opacification, congenital glaucoma, and complex systemic comorbidities; the other with anterior persistent fetal vasculature in the right eye, and Peters anomaly type 2 with cataract and iris coloboma in the left eye but no systemic issues.

Absence of Cytochrome P450-1b1 Increases Susceptibility of Pressure-Induced Axonopathy in the Murine Retinal Projection.

Front Cell Dev Biol 2021 5;9:636321. Epub 2021 Mar 5.

Department of Pharmaceutical Sciences, Northeast Ohio Medical University, Rootstown, OH, United States.

Mutations in the cytochrome P450-1B1 (Cyp1b1) gene is a common genetic predisposition associated with various human glaucomas, most prominently in primary congenital glaucoma (PCG). The role of Cyp1b1 in the eye is largely unknown, however, its absence appears to drive the maldevelopment of anterior eye structures responsible for aqueous fluid drainage in murine models. Nevertheless, vision loss in glaucoma ultimately results from the structural and functional loss of retinal ganglion cells (RGCs). Read More
