Quantitative Muscle MRI Fat Fraction as a Biomarker of Disease Severity in Mitochondrial Myopathies

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Background Quantitative muscle MRI is increasingly used to assess structural muscle damage in inherited myopathies, but its application in primary mitochondrial myopathies (PMM) has not been systematically evaluated in large cohorts. Because PMM are clinically and genetically heterogeneous, objective imaging biomarkers are needed to quantify ...

Linker molecules between laminins and dystroglycan ameliorate laminin-alpha2-deficient muscular dystrophy at all disease stages [PDF]

, 2007
Mutations in laminin-alpha2 cause a severe congenital muscular dystrophy, called MDC1A. The two main receptors that interact with laminin-alpha2 are dystroglycan and alpha7beta1 integrin.

Cracking the Code: Genotype–Phenotype Correlation Models in Sarcoglycanopathies

Annals of Clinical and Translational Neurology, Volume 13, Issue 9, Page 1851-1865, September 2026.
ABSTRACT Objective Sarcoglycanopathies are among the most severe limb‐girdle muscular dystrophies (LGMD), though milder presentations have been described. These diseases are primarily caused by missense variants, but the limited predictability of their effect on protein maturation, complex formation, and transport has hindered reliable genotype ...

Next-generation sequencing identifies transportin 3 as the causative gene for LGMD1F.

PLoS ONE, 2013
Limb-girdle muscular dystrophies (LGMD) are genetically and clinically heterogeneous conditions. We investigated a large family with autosomal dominant transmission pattern, previously classified as LGMD1F and mapped to chromosome 7q32.

Refining Shoulder Diagnostics: A Technical Note on Scapular Physical Examination

Arthroscopy Techniques, Volume 15, Issue 9, September 2026.
Abstract Normal scapulothoracic function relies on a delicate balance among several periscapular muscles and is essential for shoulder motion. Disturbance in this balance can lead to abnormal motion, which can impair shoulder function, leading to pain and discomfort.

Thrombospondin-4 deletion does not exacerbate muscular dystrophy in β-sarcoglycan-deficient and laminin α2 chain-deficient mice

Scientific Reports
Muscular dystrophy is a group of genetic disorders that lead to muscle wasting and loss of muscle function. Identifying genetic modifiers that alleviate symptoms or enhance the severity of a primary disease helps to understand mechanisms behind disease ...

Generation of an induced pluripotent stem cell (iPSC) line (JUCTCi017-A) from a patient with limb-girdle muscular dystrophy (LGMD) due to a homozygous p.Lue287Ser fs14* mutation in the SGCB gene

Stem Cell Research, 2021
Limb-girdle muscular dystrophies (LGMDs) are a large group of heterogenous genetic diseases characterized by muscle weakness. In this study, an induced pluripotent stem cell (iPSC) line was generated from LGMD patient’s skin dermal fibroblasts, carrying ...

A 12‐Year‐Old Child With a Sunken Sternum and Progressive Muscle Weakness: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT A 12‐year‐old girl with facioscapulohumeral muscular dystrophy and severe pectus excavatum presented with progressive dyspnea and restrictive ventilatory impairment. She underwent successful Nuss repair with uneventful recovery. At 6‐month follow‐up, chest contour and pulmonary function improved, suggesting that surgical correction is feasible

Pragmatic Phenotype–Electrophysiology–Genomics Integration in Pediatric Congenital Myasthenic Syndromes: Insights From 36 Patients in a Single‐Center Study in China

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
In 36 Chinese pediatric CMS patients, integrated phenotype, RNS, and genomic assessment revealed marked genetic heterogeneity across 17 CMS‐associated genes and frequent VUS‐related uncertainty. Genotype‐informed therapy improved MG‐ADL scores, while CHAT‐CMS identified a high‐risk subgroup for early respiratory failure and mortality.

AGRN‐, LRP4‐, MUSK‐Related CMS: Clinical, Neurophysiological, Morphological, Genetic and Pathological Mechanisms

Muscle &Nerve, Volume 74, Issue S1, Page S31-S40, September 2026.
ABSTRACT Congenital myasthenic syndromes (CMS) are inherited disorders caused by mutations in genes encoding proteins essential for neuromuscular junction (NMJ) function. Pathogenic variants have been identified in more than 35 genes, underscoring the complexity of synaptic biology and the wide range of mechanisms that can compromise neuromuscular ...
