Изучение спектра мутаций и совершенствование диагностики синдрома Ашера (СА) особо актуальны в связи с разрабатываемыми подходами к генной терапии заболевания. Среди 46 пациентов с признаками СА патогенные мутации выявлены нами у 40 (87%) пациентов. СА I и II типов определены у 26% и 57% пробандов исходной выборки, соответственно. У пациентов с СА I выявлены мутации в генах MYO7A (73%), CDH23 (7%), PCDH15 (7%), и USH1C (13%). Наибольшую частоту показала мутация MYO7A p.Q18*. Описано 6 новых мутаций в гене MYO7A, и две - в гене PCDH15. У пациентов с СА II выявлена 21 мутация гена USH2A, 5 из которых описаны впервые. Наибольшую частоту показала мутация USH2A p.W3955*. У двух пациентов выявлены мутации в генах несиндромального пигментного ретинита RHO и RPGR, что позволило уточнить клинический диагноз. Studying the mutation spectrum and improvement of molecular verification of the Usher syndrome (USH) are of particular relevance as gene therapy emerges. Among 46 patients with signs of Usher syndrome we identified mutations in 40 (85%) patients, establishing a diagnosis of USH1 and USH2 for 26% and 57% of the probands of the initial sample, respectively. Patients with USH1 showed mutations in the MYO7A (73%), CDH23 (7%), PCDH15 (7%), and USH1C (13%) genes. MYO7A p.Q18* mutation showed the highest frequency. We have identified 6 new mutations in the MYO7A gene, and 2 in the PCDH15 gene. In USH2 patients, 21 USH2A gene mutations were identified, 5 of which are novel. The USH2A mutation p.W3955* was most frequent. Two patients showed mutations in the non-syndromic retinitis pigmentosa genes RHO and RPGR, which made it possible to clarify the clinical diagnosis.

Optogenetic strategies to restore vision in patients who are blind from end-stage retinal degenerations aim to render remaining retinal cells light sensitive once photoreceptors are lost. Here, we assessed long-term functional outcomes following subretinal delivery of the human melanopsin gene (OPN4) in the rd1 mouse model of retinal degeneration using an adeno-associated viral vector. Ectopic expression of OPN4 using a ubiquitous promoter resulted in cellular depolarization and ganglion cell action potential firing. Restoration of the pupil light reflex, behavioral light avoidance, and the ability to perform a task requiring basic image recognition were restored up to 13 mo following injection. These data suggest that melanopsin gene therapy via a subretinal route may be a viable and stable therapeutic option for the treatment of end-stage retinal degeneration in humans.
