Genes, Vol. 15, Pages 200: Polymorphic Variants of SCN5A Gene (rs41312433 and rs1805124) Associated with Coronary Artery Affliction in Patients with Severe Arrhythmias
Conclusions: Our study presents a highly sensitive and specific association of two polymorphisms in SCN5A with significant coronary artery stenoses in patients with potentially fatal ventricular arrhythmias. At the same time, these polymorphisms were not associated with arrhythmias themselves. Thus, SCN5A gene polymorphic variants may form a part of germ cell gene predisposition to ischemia.

LncRNA CHKB-DT Downregulation Enhances Dilated Cardiomyopathy Through ALDH2
CONCLUSIONS: CHKB-DT is significantly downregulated in DCM. CHKB-DT acts as an energy metabolism-associated long noncoding RNA and represents a promising therapeutic target against DCM.PMID:38299365 | DOI:10.1161/CIRCRESAHA.123.323428 (Source: Circulation Research)

The impact of type 2 diabetes mellitus on the clinical profile, myocardial fibrosis, and prognosis in non-ischemic dilated cardiomyopathy: a prospective cohort study
The impact of the coexistence of type 2 diabetes mellitus (T2DM) in patients with non-ischemic dilated cardiomyopathy (DCM) on clinical profiles, myocardial fibrosis, and outcomes remain incompletely understood. (Source: Cardiovascular Diabetology)

Striated preferentially expressed gene deficiency leads to mitochondrial dysfunction in developing cardiomyocytes
AbstractA deficiency of striated  preferentially expressed gene (Speg), a member of the myosin light chain kinase family, results in abnormal myofibril structure and function of immature cardiomyocytes (CMs), corresponding with a dilated cardiomyopathy, heart failure and perinatal death. Mitochondrial development plays a role in cardiomyocyte maturation. Therefore, this study investigated whetherSpeg deficiency ( – / – ) in CMs would result in mitochondrial abnormalities.Speg wild-type andSpeg−/− C57BL/6 littermate mice were utilized for assessment of mitochondrial structure by transmission electron and confocal m...

Distal hereditary motor neuronopathy as a new phenotype associated with variants in BAG3
ConclusionsWe report an autosomal dominant adult-onset distal hereditary motor neuronopathy with incomplete penetrance in women as a new phenotype related to a truncating variant in theBAG3 gene. Our findings expand the phenotypic spectrum ofBAG3-related disorders, which previously included dilated cardiomyopathy, myofibrillar myopathy and adult-onset Charcot-Marie-Tooth type 2 neuropathy. Variants inBAG3 should be considered in the differential diagnosis of distal hereditary motor neuronopathies. (Source: Journal of Neurology)

Continuous Variant Re-Classification: An Effective Tool in the Ongoing Quest to Escape Genetic Purgatory
Genotype, albeit to varying degrees, impacts the diagnosis, risk-stratification, and management of many genetic heart diseases (GHDs).1 Accordingly, since the start of the new millennium, genetic testing has evolved from a research-based investigational test to a class I recommended, standard of care clinical test for patients with inherited cardiac channelopathies and cardiomyopathies such as arrhythmogenic cardiomyopathy, catecholaminergic polymorphic ventricular tachycardia, dilated cardiomyopathy, hypertrophic cardiomyopathy, and long QT syndrome (LQTS).

Transcatheter aortic valve replacement in the management of aortic insufficiency secondary to left ventricular assist device implantation: a case report
