Visual and psychological morbidity among patients with autosomal dominant optic atrophy [PDF]

Acta Ophthalmologica, 2013
Editor, Autosomal dominant optic atrophy (DOA) is the most common inherited optic nerve disorder seen in neuro-ophthalmological practice (Yu-Wai-Man et al. 2011). The majority of patients with DOA harbour pathogenic mutations within the OPA1 gene, which codes for an inner mitochondrial membrane protein intricately involved in mitochondrial ...

A 57‐Year‐Old Male With Behavioral Variant Frontotemporal Dementia and MATR3 and NOS3 Mutations

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This report presents a case of behavioral variant frontotemporal dementia caused by mutations in the MATR3 and NOS3 genes, aiming to analyze its clinical manifestations and genetic characteristics. For a case presenting with personality changes and gait abnormalities as the initial symptoms, this study conducted a comprehensive analysis of its

Long‐Term Follow Up of Two Patients With Variants in the Cluster 1031‐1159 of TRRAP Gene: Expanding the Phenotype of Developmental Delay With or Without Dysmorphic Facies and Autism

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The transformation/transcription domain‐associated protein (TRRAP) gene encodes a large multidomain protein, a member of the phosphatidylinositol 3‐kinase‐related kinase (PIKK) family. TRRAP is a component of the histone acetyltransferase (HAT) complex, and it plays an important role in gene transcription, DNA repair, and cell‐cycle regulation.

Neuroinflammatory Mechanisms of Mitochondrial Dysfunction and Neurodegeneration in Glaucoma

Journal of Ophthalmology, 2021
The exact mechanism of retinal ganglion cell loss in the pathogenesis of glaucoma is yet to be understood. Mitochondrial damage-associated molecular patterns (DAMPs) resulting from mitochondrial dysfunction have been linked to Leber’s hereditary optic ...

Defining Features of Gabriele‐de Vries Syndrome in Adults: A Case Report and Literature Review

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gabriele‐de Vries syndrome (GADEVS) is a neurodevelopmental disorder caused by heterozygous pathogenic variants in the YY1 gene. Like most rare genetic syndromes, the adult manifestations of GADEVS remain poorly defined. Here, we describe the oldest patient reported to date with GADEVS—a 63‐year‐old woman with a c.1177_1179del YY1 variant ...

Genetic testing for optic atrophy

The EuroBiotech Journal, 2017
We studied the scientific literature and disease guidelines in order to summarize the clinical utility of the genetic test for optic atrophy (OA). OA is mostly inherited in an autosomal dominant manner, rarely in an autosomal recessive manner, with an ...

New avenues for therapy in mitochondrial optic neuropathies

Therapeutic Advances in Rare Disease, 2021
Mitochondrial optic neuropathies are a group of optic nerve atrophies exemplified by the two commonest conditions in this group, autosomal dominant optic atrophy (ADOA) and Leber’s hereditary optic neuropathy (LHON).

Mutation spectrum of the OPA1 gene in a large cohort of patients with suspected dominant optic atrophy: Identification and classification of 48 novel variants.

PLoS ONE, 2021
Autosomal dominant optic atrophy is one of the most common inherited optic neuropathies. This disease is genetically heterogeneous, but most cases are due to pathogenic variants in the OPA1 gene: depending on the population studied, 32-90% of cases ...

OPA1 mutations and mitochondrial DNA haplotypes in autosomal dominant optic atrophy [PDF]

Genetics in Medicine, 2006
Autosomal dominant optic atrophy is a form of blindness, due in part to mutations affecting the mitochondrial-targeted OPA1 gene product. Both OPA1-positive and OPA1-negative families exhibit variable expressivity and incomplete penetrance. The purpose of this study was therefore to determine if the background mtDNA genotype acts as a genetic modifier ...

The EXPLAIN Study: Exploring Arthrogryposis Multiplex Congenita in Adults in Norway — A Description of Demographic, Medical, and Neurological Findings

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis Multiplex Congenita (AMC) encompasses several hundred conditions with diverse genetic, pathophysiological, and clinical origins. The overarching EXPLAIN study explores underlying causes and implications of AMC and represents the largest clinical cohort of adults with AMC reported to date.
