A mutation-agnostic and allele-specific ASO strategy demonstrates potent functional rescue and retinal preservation in RHO-linked retinitis pigmentosa

Autosomal dominant retinitis pigmentosa (adRP) caused by RHO mutations is a leading form of inherited retinal degeneration. Extensive allelic heterogeneity of RHO pathogenic variants limits the translational applicability of mutation-specific gene therapies. To address this, we developed SNARE (SNP-guided Silencing of...

Hypomorphic IDUA genotypes are associated with retinitis pigmentosa in individuals without syndromic mucopolysaccharidosis type I.

Variant-level functional assays expand the phenotypic spectrum of IDUA-associated disease to include late-onset retinal-predominant or apparently isolated retinitis pigmentosa and indicate that residual enzyme activity likely contributes to systemic sparing, highlighting the value of integrated genomic, biochemical, an...

CLUAP1 variants cause non-syndromic retinitis pigmentosa.

Clinical and molecular features of PRCD-associated retinopathy.

PURPOSE To describe the clinical and genetic characteristics of patients with biallelic disease-causing variants in the PRCD (Progressive Rod-Cone Degeneration) gene. METHODS Multicentre, retrospective cohort study of 19 patients from 13 families across nine reference centres in six countries. Clinical assessments in...

Identification of a Duplication in the RP17 Locus in an Individual With Pathogenic CEP290 Variants: Implications for RP17 Variant Classification

The cone dystrophy phenotype of the proband can be attributed to the CEP290 variants, whereas the novel RP17 duplication can be classified as likely benign based on the integrated evidence, emphasize the importance of modeling and functional studies for accurately classifying RP17-SVs and preventing misinterpretation i...

Genome sequencing reveals novel pathogenic deep-intronic PCDH15 variants, amenable to antisense oligonucleotide-based splice correction

The AP5B1 p.Leu785Pro variant is a frequent cause of late-onset macular dystrophy with variable extraocular manifestations

Findings further support AP5B1 as a cause of macular dystrophy, identify p.(Leu785Pro) as a relatively frequent pathogenic allele in individuals of European and Ashkenazi Jewish ancestry, and expand the associated phenotypic spectrum to include both isolated macular dystrophy and possible syndromic presentations.
