Ryanodine receptor 1-related disorders: an historical perspective and proposal for a unified nomenclature

Skeletal Muscle, 2020
The RYR1 gene, which encodes the sarcoplasmic reticulum calcium release channel or type 1 ryanodine receptor (RyR1) of skeletal muscle, was sequenced in 1988 and RYR1 variations that impair calcium homeostasis and increase susceptibility to malignant ...

Good response to plasmapheresis and mycophenolate mofetil in a patient with anti-synthetase syndrome associated with peripheral neuritis and severe prosthetic aortic valve stenosis

Egyptian Rheumatology and Rehabilitation, 2022
Background Idiopathic inflammatory myopathies (IIM) are a disease complex that encompasses several distinctly acquired muscle illnesses. Anti-synthetase syndrome is a subset of IIM that is characterized by the presence of antibodies against aminoacyl ...

Clinical-pathological features and muscle imaging findings in 36 Chinese patients with rimmed vacuolar myopathies: case series study and review of literature

Frontiers in Neurology, 2023
IntroductionRimmed vacuolar myopathies (RVMs) are a group of genetically heterogeneous diseases that share histopathological characteristics on muscle biopsy, including the aberrant accumulation of autophagic vacuoles. However, the presence of non-coding

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

Re‐Purposing Sapropterin (Kuvan) for ACTA2‐Related Multisystemic Smooth Muscle Dysfunction Syndrome: A Translational Mechanistic and First‐In‐Human Therapeutic Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Multisystemic smooth muscle dysfunction syndrome (MSMDS) is an ultra‐rare, ACTA2‐related disorder characterized by severe cerebrovascular disease, aortic aneurysms, and smooth muscle dysfunction. Using molecular dynamics simulations and in silico drug screening, we identified that sapropterin dihydrochloride (Kuvan) is a candidate capable of ...

Expanding the Clinico-Genetic Scope of Bethlem Myopathy: A Family of Five Patients from Kerala

Annals of Indian Academy of Neurology
Bethlem myopathy (BM) represents the milder phenotype of collagen type VI-related myopathies. We report a young male with a striking family history who presented with progressive proximal myopathy, distal joint contractures, and a unique presentation of ...

Variants in ACTC1 underlie distal arthrogryposis accompanied by congenital heart defects

HGG Advances, 2023
Summary: Contraction of the human sarcomere is the result of interactions between myosin cross-bridges and actin filaments. Pathogenic variants in genes such as MYH7, TPM1, and TNNI3 that encode parts of the cardiac sarcomere cause muscle diseases that ...

Anorectal Dysfunction in Systemic Sclerosis: Clinical Phenotypes and Functional Patterns

Arthritis Care &Research, EarlyView.
Objective The aim of this study was to characterize specific physiologic defects in anorectal dysfunction in systemic sclerosis (SSc) using anorectal manometry (ARM), evaluate associations with gastrointestinal (GI) and extraintestinal clinical phenotypes, and explore potential serologic markers for risk stratification.

CHCHD10 Mitigates Alzheimer's Disease‐Related Phenotypes in Association With Epigenetic Remodeling in Directly Reprogrammed Neurons

Advanced Science, EarlyView.
CHCHD10 loss in Alzheimer's disease is associated with mitochondrial dysfunction, epigenomic disruption, and tau pathology. Restoration of CHCHD10 shifts DNA methylation toward a non‐disease state and reduces tau and amyloid pathology, with KATNAL2 acting as a downstream effector.

Distal Myopathy

The Tohoku Journal of Experimental Medicine, 1990
Various types of the distal myopathy except Welander's late distal myopathy of Swedish type were described. There were many reports in the past concerning the varieties of the distal myopathy. Distal myopathy is a rather rare disorder and it may be difficult to diagnose these cases.
