Emery-Dreifuss muscular dystrophy (EDMD) is characterised by early contractures, slowly progressive muscle wasting and weakness with a distinctive humero-peroneal distribution and cardiac conduction defects leading to dilated cardiomyopathy. The genes known to be responsible for EDMD encode proteins associated with the nuclear envelope: the emerin and the lamins A and C.

Emery-Dreifuss Muscular Dystrophy (EDMD) is a rare genetic disorder characterized by muscle weakness, joint contractures, and cardiac dysfunction. Within this spectrum, EDMD Type 2, attributed to a heterozygous missense variant in exon 9 of the LMNA gene, presents a distinctive clinical profile. This case report details the presentation and management of a teenage girl displaying neck, trunk, upper and lower limb weakness, Achilles tendon contracture, and lordosis.

Emery-Dreifuss muscular dystrophy type 2 (EDMD2) is a rare autosomal dominant neuromuscular disorder caused by LMNA gene mutations and characterized by progressive skeletal muscle weakness and significant cardiac involvement. We report the case of a 45-year-old woman who presented with sudden-onset, left-sided hemiparesis and dysarthria. Initial imaging was unremarkable, and symptoms transiently improved, suggesting a transient ischemic attack.

Introduction: Inherited lipodystrophies are a group of rare diseases defined by severe reduction in adipose tissue mass and classified as generalized or partial. We report a non-familial (sporadic) case of partial lipodystrophy caused by a novel genetic mechanism involving closely linked pathogenic variants in the gene.
Methods: A female adult with partial lipodystrophy and her parents were evaluated for gene variants across the exome under different mendelian inheritance models (autosomal dominant, recessive, compound heterozygous, and X-linked) to find pathogenic variants.

Article Synopsis
- Skeletal muscle laminopathies (SMLs) are rare genetic disorders linked to mutations in the LMNA gene, affecting skeletal muscles.
- A 2-year study involving 26 patients aimed to understand the progression of SMLs, using various assessments for muscle performance and respiratory function.
- Results indicated a significant decline in muscle function (NSAA score) and respiratory capacity (FVC and FEV1) over two years, while other measurements like walking tests and joint flexibility remained stable.

Article Synopsis
- - Emery-Dreifuss muscular dystrophy (EDMD) is a neuromuscular disorder that leads to muscle weakness and heart problems, mainly caused by mutations in specific genes, identified through next-generation sequencing (NGS).
- - The study examined two Moroccan patients with EDMD, revealing one with a known splicing variant and another with a new frameshift variant, along with testing relatives for carrier status.
- - The findings highlight NGS as crucial for accurately diagnosing EDMD, managing patient care, and providing genetic counseling to affected families.
