Autosomal dominant optic atrophy: A novel treatment for OPA1 splice defects using U1 snRNA adaption

Mol Ther Nucleic Acids. 2021 Oct 21;26:1186-1197. doi: 10.1016/j.omtn.2021.10.019. eCollection 2021 Dec 3. ABSTRACT Autosomal dominant optic atrophy (ADOA) is frequently caused by mutations in the optic atrophy 1 (OPA1) gene, with haploinsufficiency being the major genetic pathomechanism. Almost 30% of the OPA1-associated cases suffer from splice defects. We identified a novel OPA1 mutation, c.1065+5G>A, […]

Induced Pluripotent Stem Cells for Inherited Optic Neuropathies-Disease Modeling and Therapeutic Development

J Neuroophthalmol. 2022 Mar 1;42(1):35-44. doi: 10.1097/WNO.0000000000001375. Epub 2021 Sep 30. ABSTRACT BACKGROUND: Inherited optic neuropathies (IONs) cause progressive irreversible visual loss in children and young adults. There are limited disease-modifying treatments, and most patients progress to become severely visually impaired, fulfilling the legal criteria for blind registration. The seminal discovery of the technique for […]

Red Light Irradiation In Vivo Upregulates DJ-1 in the Retinal Ganglion Cell Layer and Protects against Axotomy-Related Dendritic Pruning

Int J Mol Sci. 2021 Aug 4;22(16):8380. doi: 10.3390/ijms22168380. ABSTRACT Retinal ganglion cells (RGCs) undergo dendritic pruning in a variety of neurodegenerative diseases, including glaucoma and autosomal dominant optic atrophy (ADOA). Axotomising RGCs by severing the optic nerve generates an acute model of RGC dendropathy, which can be utilized to assess the therapeutic potential of […]

Associations between OPA1, MFN1, and MFN2 polymorphisms and primary open angle glaucoma in Polish participants of European ancestry

Ophthalmic Genet. 2022 Feb;43(1):42-47. doi: 10.1080/13816810.2021.1970197. Epub 2021 Aug 23. ABSTRACT BACKGROUND: Glaucomatous optic nerve damage is caused by selective death of retinal ganglion cells (RGCs). Another condition with underlying loss of RGCs is autosomal dominant optic atrophy (ADOA). Majority of ADOA patients have mutations in OPA1, gene responsible for mitochondrial fusion final steps. Clinical […]

Sustained intracellular calcium rise mediates neuronal mitophagy in models of autosomal dominant optic atrophy

Cell Death Differ. 2022 Jan;29(1):167-177. doi: 10.1038/s41418-021-00847-3. Epub 2021 Aug 13. ABSTRACT Mitochondrial dysfunction and mitophagy are often hallmarks of neurodegenerative diseases such as autosomal dominant optic atrophy (ADOA) caused by mutations in the key mitochondrial dynamics protein optic atrophy 1 (Opa1). However, the second messengers linking mitochondrial dysfunction to initiation of mitophagy remain poorly […]

Expectation-Maximization-Based Simultaneous Localization and Mapping for Millimeter-Wave Communication Systems

Sensors (Basel). 2022 Sep 14;22(18):6941. doi: 10.3390/s22186941. ABSTRACT In this paper, we proposed a novel expectation-maximization-based simultaneous localization and mapping (SLAM) algorithm for millimeter-wave (mmW) communication systems. By fully exploiting the geometric relationship among the access point (AP) positions, the angle difference of arrival (ADOA) from the APs and the mobile terminal (MT) position, and […]

Autosomal dominant optic atrophy caused by six novel pathogenic OPA1 variants and genotype-phenotype correlation analysis

BMC Ophthalmol. 2022 Jul 26;22(1):322. doi: 10.1186/s12886-022-02546-0. ABSTRACT PURPOSE: To describe the genetic and clinical features of nineteen patients from eleven unrelated Chinese pedigrees with OPA1-related autosomal dominant optic atrophy (ADOA) and define the phenotype-genotype correlations. METHODS: Detailed ophthalmic examinations were performed. Targeted next-generation sequencing (NGS) was conducted in the eleven probands using a custom […]

Prevalence of Macular Microcystoid Lacunae in Autosomal Dominant Optic Atrophy Assessed With Adaptive Optics

J Neuroophthalmol. 2022 Sep 1;42(3):328-333. doi: 10.1097/WNO.0000000000001592. Epub 2022 Mar 30. ABSTRACT BACKGROUND: To assess the prevalence of macular microcystoid lacunae in patients with autosomal dominant optic atrophy (ADOA) and its association with visual function and inner retinal morphology. METHODS: The study included 140 participants with ADOA, with a mean age of 44 (SD ±19, […]

First Description of Inheritance of a Postzygotic OPA1 Mosaic Variant

Genes (Basel). 2022 Mar 8;13(3):478. doi: 10.3390/genes13030478. ABSTRACT Optic atrophy 1 (MIM #165500) is caused by pathogenic variants in the gene OPA1 (OPA1 MITOCHONDRIAL DYNAMIN-LIKE GTPase, MIM *605290) and is inherited in an autosomal dominant manner. We describe a 6-year-old male patient with severe early onset manifestation of optic atrophy, whose parents are subjectively asymptomatic. […]
