Single-gene neurological disorders in South Wales: an epidemiological study.

Ann Neurol

Institute of Medical Genetics for Wales, University of Wales College of Medicine, Heath Park, Cardiff, United Kingdom.

Published: September 1991

Single-gene neurological disorders account for a significant proportion of the work load of any regional genetics unit. In an attempt to assess the likely impact of recombinant DNA technology on these debilitating diseases, a population prevalence study of the major neurogenetic diseases was carried out in the South Wales region of Great Britain. The minimum overall prevalence of these disorders was estimated to be 58.6/100,000 population.

Diagnosis of hereditary ataxias: a real-world single center experience.

J Neurol

January 2025

Neurological Institute, Department of Clinical and Experimental Medicine, University of Pisa, Pisa, Italy.

Objective: This study aims to evaluate our experience in the diagnosis of hereditary ataxias (HAs), to analyze data from a real-world scenario.

Study Design: This is a retrospective, cross-sectional, descriptive study conducted at a single Italian adult neurogenetic outpatient clinic, in 147 patients affected by ataxia with a suspicion of hereditary forms, recruited from November 1999 to February 2024. A stepwise approach for molecular diagnostics was applied: targeted gene panel (TP) next-generation sequencing (NGS) and/or clinical exome sequencing (CES) were performed in the case of inconclusive first-line genetic testing, such as short tandem repeat expansions (TREs) testing for most common spinocerebellar ataxias (SCA1-3, 6-8,12,17, DRPLA), other forms [Fragile X-associated tremor/ataxia syndrome (FXTAS), Friedreich ataxia (FRDA) and mitochondrial DNA-related ataxia, RFC1-related ataxia/CANVAS] or inconclusive phenotype-guided specific single gene sequencing.

Extreme Phenotypic Variability of -Related Disorders in Hearing Loss.

Adv Genet (Hoboken)

December 2024

Instituto de Química Biológica de la Facultad de Ciencias Exactas y Naturales (IQUIBICEN) CONICET Buenos Aires 1428 Argentina.

Hearing loss is the most common sensory defect in humans, affecting normal communication. In most cases, hearing loss is a multifactorial disorder caused by both genetic and environmental factors, but single-gene mutations can lead to syndromic or non-syndromic hearing loss. Monoallelic variants in , coding for gamma (γ)-actin, are associated with classical Baraitser-Winter Syndrome type 2 (BRWS2, nonsyndromic deafness, and a variety of clinical presentations not fitting the original BRWS2 description or nonsyndromic deafness.

Importance: Single gene variants can cause cerebral palsy (CP) phenotypes, yet the impact of genetic diagnosis on CP clinical management has not been systematically evaluated.

Objective: To evaluate how frequently genetic testing results would prompt changes in care for individuals with CP and the clinical utility of precision medicine therapies.

Data Sources: Published pathogenic or likely pathogenic variants in OMIM genes identified with exome sequencing in clinical (n = 1345) or research (n = 496) cohorts of CP were analyzed.

Article Synopsis
  • There is considerable evidence suggesting that changes in dopamine signaling are linked to neuropsychiatric disorders like ADHD and other behavioral traits over the past 40 years.
  • The review focuses on the key elements of dopamine signaling in the brain, particularly looking at enzymes, transporters, and receptors involved in this process, with a specific focus on areas related to ADHD.
  • While dopamine is implicated in ADHD, there's limited support for the notion that a general lack of dopamine is the primary issue; future research should explore how dopamine interacts with other neurotransmitters and its role during brain development in different clinical subgroups.*

Article Synopsis
  • - Neurological diseases caused by single gene defects can be treated through AAV-mediated gene therapy, but delivering this therapy to the brain is difficult because of the blood-brain barrier.
  • - Advanced techniques, like convection-enhanced delivery and image-guided methods to cerebrospinal fluid spaces, allow for precise gene therapy delivery to target specific brain areas.
  • - Neuroimaging methods, including MRI and fMRI, are crucial for both delivering AAV vectors and monitoring the effectiveness of the gene therapy over time.
