Purpose Of Review: The purpose of this review is to provide an update on lamin A/C (LMNA)-related cardiomyopathy and discuss the current recommendations and progress in the management of this disease. LMNA-related cardiomyopathy, an inherited autosomal dominant disease, is one of the most common causes of dilated cardiomyopathy and is characterized by steady progression toward heart failure and high risks of arrhythmias and sudden cardiac death.
Recent Findings: We discuss recent advances in the understanding of the molecular mechanisms of the disease including altered cell biomechanics, which may represent novel therapeutic targets to advance the current management approach, which relies on standard heart failure recommendations. Future therapeutic approaches include repurposed molecularly directed drugs, siRNA-based gene silencing, and genome editing. LMNA-related cardiomyopathy is the focus of active in vitro and in vivo research, which is expected to generate novel biomarkers and identify new therapeutic targets. LMNA-related cardiomyopathy trials are currently underway.

Purpose Of Review: This review highlights the diverse cardiac manifestations of LMNA mutations, focusing on their underlying molecular mechanisms and clinical implications. As LMNA mutations are implicated in cardiomyopathies, such as dilated cardiomyopathy (DCM), arrhythmogenic cardiomyopathy (ARVC), and conduction system diseases, understanding these phenotypes is critical for advancing diagnosis and management strategies.
Recent Findings: Recent studies reveal that LMNA mutations disrupt nuclear envelope stability, activating the DNA damage response (DDR) and compromising chromatin organization and mechanotransduction.

Background: Pathogenic variations in lamin A/C (LMNA) result in a group of inherited conditions termed laminopathies. Cardiac manifestations of laminopathies include atrial and ventricular arrhythmias, atrioventricular conduction disorders, and cardiomyopathy, with or without skeletal muscle involvement. Because of rarity and previous cardiac characterization as adult onset, pediatric data are limited.

Purpose Of Review: This review aims to explore how a diagnosis of LMNA-related cardiomyopathy (LMNA-CM) informs clinical management, focusing on the prevention and management of its complications, through practical clinical strategies.
Recent Findings: Longitudinal studies have enhanced our understanding of the natural history of LMNA-CM including its arrhythmic and non-arrhythmic complications. A LMNA specific ventricular arrhythmia risk prediction strategy has been integrated into clinical practice guidelines.

Background: The genetic variants of LMNA cause an array of diseases that often affect the heart. LMNA-related cardiomyopathy exhibits high-penetrance and early-onset phenotypes that lead to late-stage heart failure or lethal arrhythmia. As a subtype of dilated cardiomyopathy and arrhythmogenic cardiomyopathy, LMNA-related cardiac dysfunction is resistant to existing cardiac therapeutic strategies, leaving a major unmet clinical need in cardiomyopathy management.
