- Voltage-gated (Kv) potassium channels are critical for neuronal physiology, and their dysfunction can lead to serious consequences. For example, mutations in the silent modulatory Kv8.2 subunit are known to cause irreversible inherited blindness (KCNV2 retinopathy). This is a currently incurable condition that causes lifelong visual loss, reduced visual acuity, photoaversion, night blindness and abnormal colour vision, alongside a distinctive supernormal electrophysiological (ERG) retinal response to light. In this study, we demonstrate that AAV-mediated gene replacement therapy delivering a codon-optimised human KCNV2 gene subretinally into Kv8.2 knock-out mice significantly restores retinal function. Treated mice exhibited improved ERG responses and correct expression of KCNV2 and its encoded Kv8.2 protein in photoreceptors. Recovery of visually guided scotopic and photopic optomotor responses to wildtype levels was achieved at lower vector doses, highlighting dose-dependent efficacy. Furthermore, treatment of human retinal organoids derived from a KCNV2 patient iPSC line resulted in substantial Kv8.2 protein rescue. This work provides the preclinical proof-of-concept for the safety and therapeutic potential of gene therapy for KCNV2 retinopathy, laying a strong foundation for future clinical trials. - Source: PubMed

Patients have characteristic electroretinography abnormalities, including reduced cone response, delayed and reduced rod response to low light flashes and paradoxically large rod-driven response to bright flashes of light. To model this condition, we have generated a Kcnv2 E151X mouse line and assessed its structural and functional retinal features. - Source: PubMed

Xhaferri NerminaBiswas SumitDavies BenjaminLindner Moritz - Voltage-gated potassium channel genes are among the most frequently implicated in epilepsy and antiseizure medication (ASM) response. In this pilot study, we aimed to identify rare and common variants by sequencing voltage-gated potassium channel (Kv) genes in epilepsy patients using ASM, and to reveal the potential drug responses of these variants. To investigate the role of genetic variants in Kv genes (, , , , , and ) in response to ASMs among 31 epilepsy patients, we used targeted next-generation sequencing (tNGS). Patients were classified as responders or persistent based on seizure control status. Selected variants in the genes were annotated, filtered, and analyzed for association with ASM response. We identified 181 variants in the 6 channel genes, including missense, synonymous, intronic, UTR, and stop-gained variants. Six variants of uncertain significance (VUSs) were observed, including c.*1314C>T, c.*976G>A, (c.2613G>T p.Arg871Ser and c.1148+62T>G), and (c.*6282A>G and c.*2860T>C) Two novel variants were identified in our study group, :c.*1314C>T and :c.*2860T>C. Both were located in the 3' UTR region and classified as VUSs according to ACMG guidelines. In the gene, the CG haplotype comprising rs7029012 and rs10967705 was observed more frequently in patients with drug-persistent epilepsy than in those with drug-responsive epilepsy (18.5% vs. 0.8%; χ = 6.756, = 0.009, BH-FDR = 0.036), suggesting a potential association with pharmacoresistant epilepsy. Our haplotype analysis suggests the potential pharmacogenetic contribution of the gene to ASM response; however, these exploratory findings require validation in larger independent cohorts and functional studies. - Source: PubMed

Pekkoc-Uyanik Kubra CigdemTodurga-Seven Zeynep GizemAgay Erhan RasitUzun Hafize - Cone dystrophy with supernormal rod responses (CDSRR) is a rare autosomal recessive hereditary retinal dystrophy caused by biallelic variants. Accurate prevalence data remain limited because current estimates rely on clinically ascertained cases. This study aimed to estimate its population prevalence by integrating curated variant evidence and large-scale population genomics resources. The key methodological feature of this study is a multi-tiered pathogenicity framework combined with estimation of a biologically plausible prevalence range: Known pathogenic variants define conservative estimates, whereas probably pathogenic variants and strong variants of uncertain significance define broader estimates. Allele frequencies were analyzed in 807,162 individuals from the gnomAD database and 144,127 Russian genomes from GDB and EvogenDB. A Bayesian framework was applied to calculate disease prevalence from aggregated carrier frequencies across predefined variant tiers. Conservative estimates based on known pathogenic variants, were 1 in 343,926 globally and 1 in 1,911,347 in Russia. Including broader tiers increased estimates to 1 in 14,620 and 1 in 32,764, respectively. Compared to previous clinically ascertained prevalence of 1 in 865,000, these estimates define a wider biologically plausible prevalence range and are consistent with possible clinical underascertainment. This tier-based approach accounts for uncertainty in variant classification when estimating rare disease prevalence. - Source: PubMed
