Article Synopsis
- Dystonia is a common movement disorder with a complex genetic background, showing significant variability in its clinical presentation and genetics.
- The study involved exome sequencing of nearly 1,924 patients, mainly from two major registries, focusing on those with genetic prescreening negative results and early age at onset.
- Researchers discovered 137 likely pathogenic variants in 51 genes among the patients, with many being novel, highlighting the challenges in diagnosing and understanding the disorder's genetic links.
Article Synopsis
- A large-scale genome-wide association study (GWAS) was conducted with over 6000 participants to investigate genetic risk factors for isolated dystonia, aiming to improve upon earlier studies that found no significant genetic links.
- The study included 4303 dystonia patients and 2362 healthy controls, analyzing various factors like age of onset and affected body areas, but ultimately failed to identify any common genetic variants associated with dystonia.
- The findings suggest that isolated dystonia may not be influenced by common genetic variations, highlighting the need for more extensive studies like whole-genome sequencing to uncover potential genetic contributions.
Article Synopsis
- Pathogenic heterozygous mutations in the GRN gene are a significant cause of frontotemporal dementia (FTD), leading to lower levels of the progranulin protein in biofluids, which has sparked therapeutic trials aimed at increasing these levels.
- A systematic review of literature on biofluid PGRN concentrations included data from 7071 individuals, primarily focusing on plasma PGRN levels derived from a single assay type, which accounted for variations based on mutation type, age, sex, and clinical diagnosis.
- Key findings established specific concentration cut-offs for plasma (74.8 ng/mL) and CSF (3.43 ng/mL) and indicated that plasma PGRN levels vary by mutation type,
Background: Dystonia is one of the most common movement disorders. To date, the genetic causes of dystonia in populations of European descent have been extensively studied. However, other populations, particularly those from the Middle East, have not been adequately studied.
