Cracking the Code: Genotype-Phenotype Correlation Models in Sarcoglycanopathies.
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-phenotype correlations. This study aimed to establish accurate genotype-phenotype correlations for LGMDR3, LGMDR4, and LGMDR5. We analyzed the largest sarcoglycanopathy cohort to date (n = 541). Clinical data, including age at symptom onset and loss of ambulation, were collected and used to define phenotype severity. Predictive models were developed considering the impact of non-truncating variants on secondary structure, functional domains, evolutionary conservation, and intra-complex protein-protein interactions. Patients carrying two variants predicted to disrupt membrane trafficking were expected to present with severe phenotypes. For LGMDR3, the best-performing model classified variants affecting β-sheets, cadherin-like, and ATP-binding domains as disruptive to membrane translocation, achieving 89% predictive power, 0.867 balanced accuracy, and 2.4% false-negative rate (clinically severe patients who were wrongly classified by the model as mild). For LGMDR4 and LGMDR5, the best-performing model involved conserved residues, β-sheets, EGF-like domain, and protein-protein interactions-reaching 80% predictive power, 0.689 balanced accuracy, and 3.1% false-negative rate (LGMDR4), and 90% predictive power, 0.536 balanced accuracy, with no false negatives (LGMDR5). Additionally, we developed an open-access predictive tool for clinical and research application. This study provides a robust genotype-phenotype correlation for sarcoglycanopathies, improving prognosis, patient management, and clinical trial recruitment.
SORT LNPs encapsulating Cas9 mRNA achieve efficient editing in skeletal muscle in a dystrophic mouse model.
Limb Girdle Muscular Dystrophy (LGMD) is the fourth most common type of muscular dystrophy. Gene editing holds promise for treating neuromuscular disorders such as LGMD, but clinical translation remains challenging due to lack of complementary delivery tools for skeletal muscle. Lipid nanoparticles (LNPs) offer a promising platform for transient delivery of gene editing reagents as mRNA or ribonucleoprotein complexes (RNPs) to skeletal muscle but editing efficiencies remain modest. While lipid compositions have been optimized to improve delivery to muscle, the impact of cargo type on editing efficiency, biodistribution and immune response has not been evaluated. Here we demonstrate that selective organ targeting (SORT) LNPs encapsulating optimized Cas9 cargo facilitate efficient, local delivery to skeletal muscle. Using a LGMDR7 mouse model harboring a mutation in TCAP as a proof-of-concept target, we show that LNP cargo type impacts LNP size, delivery to neighboring muscle groups and editing efficiency. RNP and mRNA LNPs also provoked distinct innate and adaptive immune responses upon repeated dosing. The optimized SORT LNP platform resulted in 40% restoration of Telethonin expression in treated muscle. Overall, these findings offer valuable insights for the continued development of LNP-based gene editing reagents to facilitate disease-modifying interventions for neuromuscular diseases.
Statins in Genetic Myopathies: A Retrospective Analysis of Safety and Tolerability.
Statins are widely prescribed lipid-lowering agents, but their safety and tolerability in patients with underlying genetic myopathies remain uncertain. We aimed to study statin safety and tolerability in genetic myopathies using a large retrospective cohort. We conducted a retrospective study in patients with myotonic dystrophy type 1 (DM1) and type 2 (DM2), facioscapulohumeral dystrophy (FSHD), limb-girdle muscular dystrophy (LGMD), and metabolic or mitochondrial myopathies who were exposed to statins. We included 135 patients (36 with DM1, 46 with DM2, 22 with FSHD, 6 with LGMD, 17 with mitochondrial myopathy, 6 with glycogenosis, and 2 with disorders of fatty acid oxidation or carnitine transport). A total of 44 patients discontinued statins, most often for statin-associated muscle symptoms (SAMS; n = 20). SAMS occurred in 36 of 135 patients (26.67%; 8 with DM1, 10 with DM2, 7 with FSHD, 3 with LGMD, 4 with mitochondrial myopathy, and 4 with metabolic myopathy). Myalgias were the most frequent SAMS (n = 29). Rhabdomyolysis occurred in 4 patients (1 with mitochondrial myopathy and 3 with McArdle disease). Statins unmasked myopathy in 6 of 36 patients. No patient developed immune-mediated necrotizing myopathy. SAMS are generally mild and occur at a frequency similar to the general population in common genetic myopathies, except increased rhabdomyolysis in mitochondrial myopathies and McArdle disease. Statins are generally safe, though not well tolerated, and could be used when closely monitored in several genetic myopathies. In mitochondrial and metabolic myopathies, their use should be approached with caution because of the potential risk of rhabdomyolysis.
Clinical and Genetic Analysis of Limb-Girdle Muscular Dystrophy Type 2F with A Novel SGCD Mutation: A Case Report.
Limb-girdle muscular dystrophies (LGMDs) represent a varied group of genetic disorders characterised by the progressive weakening and atrophy of proximal muscles, particularly those in the shoulders and hips. These conditions are inherited in either an autosomal dominant or recessive pattern, with numerous genes implicated in their pathogenesis. Clinically, LGMDs are marked by a gradual decline in muscle function, often resulting in significant mobility impairments. In this study, we identify and characterise a novel homozygous deletion mutation, c.572_574delTAA, in the SGCD gene in a consanguineous Iranian family affected by LGMD2F. The patient, a 10.5-year-old boy, exhibited progressive muscle weakness alongside specific clinical features such as contractures and scoliosis. Genetic analysis revealed that this deletion caused a p.Leu191del alteration in the δ-sarcoglycan protein. The mutation was confirmed via Sanger sequencing and found to co-segregate with the disease phenotype within the family. These findings provide new insights into the genetic basis of LGMD2F, underscoring the critical role of comprehensive genetic analysis for accurate diagnosis and management. This study contributes to the broader understanding of the genetic diversity of LGMDs and highlights the need for ongoing research to enhance diagnostic and therapeutic approaches.
SNUPN variants cause spinocerebellar atrophy by disrupting global splicing in cerebellar Purkinje cells.
Mutations in the SNUPN gene, which encodes snurportin-1, a nuclear import adaptor for U1 small nuclear ribonucleoproteins (snRNP), have recently been implicated in limb-girdle muscular dystrophy, attributed to disrupted pre-messenger RNA splicing in skeletal muscle. U1 small nuclear ribonucleoproteins play a vital role in pre-messenger RNA splicing, a process essential for transcript fidelity and the regulation of gene expression across tissues. However, the impact of SNUPN mutations on the CNS remains unclear. We identified pathogenic variants in the SNUPN gene in two families with spinocerebellar atrophy. One patient exhibited mild changes in skeletal muscle, while the other did not. To elucidate the pathogenic mechanisms, nuclear transport of the mutated snurpotin-1, and its interaction with importin beta were analysed in vitro. Then, we generated a knock-in mouse carrying the patients' variants and assessed its motor function and cerebellar morphology in vivo. Furthermore, we analysed U1 snRNP localization and RNA splicing in cerebellar Purkinje cells by both RNA- and single-cell RNA sequencing. Mutated snurportin-1 displayed impaired nuclear transport and reduced binding to importin beta. The knock-in mouse mimicking the compound heterozygous variants exhibited cerebellar ataxia, cerebellar atrophy and dendritic abnormalities in Purkinje cells. Abnormal RNA splicing and reduced expression were observed in many genes related to neuronal development and synaptic organization in Purkinje cells, leading to an immature cytoskeleton and reduced secretion of sonic hedgehog. The defects in Purkinje cells caused secondary abnormalities in granule cell migration and interneuron development. Our findings suggest that snurportin-1 plays a critical role in cerebellar development through U1 snRNP-mediated RNA processing and that its dysfunction may contribute to spinocerebellar ataxia. These results expand the clinical spectrum of SNUPN-related disorders beyond skeletal muscle and highlight splicing dysregulation as a potential mechanism underlying cerebellar atrophy.
