Purpose: To report the clinical presentation and follow-up, including the optical coherence tomography, angiography and electrophysiology of two individuals from the same family presenting with an isolated retinal dystrophy and optic nerve edema who were diagnosed with ROSAH-like syndrome.
Method: Observational case report of a 55-year-old woman and her 36-year-old son with a genetic analysis of ROSAH, after a long-term follow-up.
Results: Both the mother and her son displayed severe optic nerve infiltration and retinal pigment atrophy with intraocular inflammation, which were not improved by immunosuppressive treatment.
Article Synopsis
- - POLG deficiency is the most common cause of nuclear-encoded mitochondrial disorders, leading to a range of overlapping symptoms from infancy to adulthood, as seen in a study of 40 children with biallelic pathogenic variants.
- - The study identified three main clinical patterns (neurologic, hepatic, gastrointestinal), with 24 patients requiring urgent care mainly due to severe neurologic issues like seizures and epilepsy.
- - Most children with hepatic symptoms had the earliest onset and shortest survival rates, while those with gastrointestinal issues had milder symptoms and lived longer; overall, the prognosis was poor, with many fatalities occurring by age 10.
Background: The pathophysiology of toxico-nutritional optic neuropathies remains debated, with no clear understanding of the respective roles played by the direct alcohol toxicity, smoking and the often associated vitamin deficiencies, which are risk factors for optic neuropathy. Our aim was to investigate genetic susceptibility in patients with bilateral infraclinical optic neuropathy associated with chronic alcohol use disorder.
Methods: This retrospective cohort study included 102 visually asymptomatic patients with documented alcohol use disorder from a French reference center.
Objective: The objective of this study was to evaluate the implementation of NGS within the French mitochondrial network, MitoDiag, from targeted gene panels to whole exome sequencing (WES) or whole genome sequencing (WGS) focusing on mitochondrial nuclear-encoded genes.
Methods: Over 2000 patients suspected of Primary Mitochondrial Diseases (PMD) were sequenced by either targeted gene panels, WES or WGS within MitoDiag. We described the clinical, biochemical, and molecular data of 397 genetically confirmed patients, comprising 294 children and 103 adults, carrying pathogenic or likely pathogenic variants in nuclear-encoded genes.
