141: RetiGene: a gene atlas for inherited retinal diseases

Rivolta C et al., The American Journal of Human Genetics - RetiGene is an expert‑curated, openly accessible atlas integrating variant data, bulk and single‑cell RNA‑seq, and functional annotations for genes linked to inherited retinal diseases to aid diagnosis and research. Key terms: RetiGene, inherited retinal diseases, gene atlas, single-cell RNA-seq, diagnostic genetics.

Study Highlights:
The authors manually curated 470 genes (plus 4 loci) strongly associated with inherited retinal diseases and flagged 196 candidate genes and 17 discarded genes based on evidence strength. They integrated variant annotations, bulk (FANTOM5) and single‑cell RNA‑seq, and Gene Ontology‑based functional classifications to map genotype–phenotype relationships. Ciliary genes form the largest functional category and autosomal recessive inheritance predominates; expression patterns help explain syndromic versus non‑syndromic presentations. The resource is hosted at retigene.erdc.info and is intended for regular updates to support diagnostics, gene prioritization, and therapeutic development.

Conclusion:
RetiGene provides a continuously updated, expert‑curated gene atlas that integrates genetic and expression data to improve molecular diagnosis, panel design, and functional studies of inherited retinal diseases.
