Special Issue Information

Dear Colleagues,

Inherited retinal degenerative diseases (IRDs) are a diverse group of genetic disorders that lead to progressive vision loss and, in many cases, blindness. These conditions, including retinitis pigmentosa, Stargardt disease, and Leber congenital amaurosis, are caused by mutations in more than 270 identified genes affecting photoreceptor cells and the retinal pigment epithelium. Recent advances in next-generation sequencing, genome-wide association studies, and functional genomics have significantly enhanced our understanding of IRD pathogenesis. Novel gene discoveries continue to refine diagnostic approaches, enabling earlier and more precise genetic testing.

This Special Issue of Genes highlights the latest research in IRD genetics, covering emerging disease mechanisms, new gene discoveries, innovative diagnostic tools, and advancements in precision medicine.

The history of these diseases began in the 19th century, with early clinical descriptions of retinitis pigmentosa (RP) and other IRDs by ophthalmologists like Albrecht von Graefe (1857) and Frans Cornelis Donders (1869). Research in CRISPR, stem cells, and retinal implants continues to revolutionize treatment possibilities.

Recent advancements in the field of inherited retinal dystrophies (IRDs) have led to groundbreaking treatments that offer hope for individuals affected by these genetic conditions. Additionally, breakthroughs in gene therapy, genome editing (e.g., CRISPR-Cas9), and RNA-based therapies are paving the way for targeted treatments, some of which have already reached clinical application.

We welcome original research articles, reviews, and perspectives from experts in genetics, molecular biology, and ophthalmology. We invite you to contribute to this Special Issue and share your findings to further advance the field of inherited retinal diseases.

Inherited retinal dystrophies (IRDs) are a diverse group of monogenic disorders associated with dysfunction of the retina. High myopia, commonly defined as a spherical equivalent ≤ −6.00 D or axial length ≥ 26.5 mm, is a recurring clinical feature across several IRDs, and [...] Read more.
Inherited retinal dystrophies (IRDs) are a diverse group of monogenic disorders associated with dysfunction of the retina. High myopia, commonly defined as a spherical equivalent ≤ −6.00 D or axial length ≥ 26.5 mm, is a recurring clinical feature across several IRDs, and could serve as an early diagnostic clue. This review provides a summary of IRDs associated with high myopia to guide the clinician in establishing a molecular diagnosis for patients. We performed a comprehensive literature review of articles in PubMed, ScienceDirect, and JAMA Network to identify associations between monogenic IRDs and high myopia. Genes associated with IRDs and high myopia clustered into functional categories that included collagen/structural integrity (COL2A1, COL9A1, COL11A1, COL18A1, P3H2), phototransduction and visual cycle (PDE6C, PDE6H, GUCY2D, ARR3, RBP3), ciliary trafficking and microtubule-associated genes (RPGR, RP2, IFT140, CFAP418, FAM161A), synaptic ribbon and bipolar cell signaling (NYX, CACNA1F, TRPM1, GRM6, LRIT3, GPR179), opsin-related genes (OPN1LW, OPN1MW), and miscellaneous categories (VPS13B, ADAMTS18, LAMA1). Associations between IRDs and high myopia spanned stationary and progressive retinal disorders and included both cone-dominant and rod-dominant diseases. High myopia accompanied by other visual symptoms and signs such as nyctalopia, photophobia, or reduced best-corrected visual acuity should heighten suspicion for an underlying IRD. Earlier diagnosis of IRDs for patients could facilitate timely genetic counseling, participation in clinical trials, and interventions for patients to preserve vision.: Full article
