Article Synopsis
- Nemaline myopathy (NM) is a muscle disorder characterized by a wide range of clinical severity, largely influenced by specific genetic mutations, with ACTA1 being a key gene linked to severe cases.
- Researchers studied a cohort of ten families with severe NM, finding that affected individuals often faced significant muscle weakness from birth and many did not survive beyond the early months of life; DNA testing revealed mutations in the ACTA1 gene for all cases.
- Muscle biopsy analysis showed distinctive NM histopathology, such as abnormal muscle structure and changes in nuclear organization, which were validated by examining similar cases, suggesting a deeper understanding of the disease's genetic and structural complexities.
Objective: To describe the clinical and molecular features of a group of Argentinian pediatric patients with mitochondrial DNA (mtDNA) disorders, and to evaluate the results of the implementation of a classical approach for the molecular diagnosis of mitochondrial diseases.
Methods: Clinical data from 27 patients with confirmed mtDNA pathogenic variants were obtained from a database of 89 patients with suspected mitochondrial disease, registered from 2014 to 2020. Clinical data, biochemical analysis, neuroimaging findings, muscle biopsy and molecular studies were analyzed.
Background: Vasculitic peripheral neuropathy (VPN) is caused by vessel inflammation leading to peripheral nerve injury of acute-to-subacute onset. When VPN occurs in the context of systemic disease it is classified as Systemic Vasculitic Neuropathy (SVN) and as Non-Systemic Vasculitic Neuropathy (NSVN) when restricted to the nerves.
Objective: This study aimed to compare the clinical characteristics, biopsy findings and disease outcome in patients with VPN.
Autosomal dominant limb girdle muscular dystrophy D3 HNRNPDL-related is a rare dominant myopathy caused by mutations in HNRNPDL. Only three unrelated families have been described worldwide, a Brazilian and a Chinese carrying the mutation c.1132G>A p.

We recharacterized the RYR1-recessive morphological spectrum by a large monocentric study performed on 54 muscle biopsies from a large cohort of 48 genetically confirmed patients, using histoenzymology, immunohistochemistry, and ultrastructural studies. We also analysed the level of RyR1 expression in patients' muscle biopsies.
