Article Synopsis
  • * Among 82 LQTS patients, a 75% diagnostic yield was found in those with high Schwartz scores, while 50% of those with lower scores (<3.5) were diagnosed through broader genetic testing.
  • * The findings suggest that the existing LQTS genetic diagnosis framework may not effectively capture cases with lower Schwartz scores, and additional rare variants could indicate more severe disease, pointing towards the need for improved referral criteria.

A genetic diagnosis of primary cardiomyopathies can be a long-unmet need in patients with complex phenotypes. We investigated a three-generation family with cardiomyopathy and various extracardiac abnormalities that had long sought a precise diagnosis. The 41-year-old proband had hypertrophic cardiomyopathy (HCM), left ventricular noncompaction, myocardial fibrosis, arrhythmias, and a short stature.

Variants of the gene have been associated with a number of primary cardiac conditions, including left ventricular noncompaction cardiomyopathy (LVNC). Most cases of -related diseases are associated with such variant types as missense substitutions and in-frame indels. Thus, truncating variants in (tv) and associated mechanism of haploinsufficiency are usually considered not pathogenic in these disorders.

Left ventricular noncompaction (LVNC) is a highly heterogeneous primary disorder of the myocardium. Its clinical features and genetic spectrum strongly overlap with other types of primary cardiomyopathies, in particular, hypertrophic cardiomyopathy. Study and the accumulation of genotype-phenotype correlations are the way to improve the precision of our diagnostics.

Familial hypercholesterolemia (FH) is a common autosomal codominant disorder, characterized by elevated low-density lipoprotein cholesterol levels causing premature atherosclerotic cardiovascular disease. About 2900 variants of , , and genes potentially associated with FH have been described earlier. Nevertheless, the genetics of FH in a Russian population is poorly understood.

Magnetic hyperthermia (MHT) is a promising approach for cancer therapy. However, a systematic MHT characterization as function of temperature on the therapeutic efficiency is barely analyzed. Here, we first perform comparative temperature-dependent analysis of the cobalt ferrite nanoparticles-mediated MHT effectiveness in two murine tumors models - breast (4T1) and colon (CT26) cancer in vitro and in vivo.

Inflammation is one of the key processes in the pathogenesis of atherosclerosis. Numerous studies are focused on the local inflammatory processes associated with atherosclerotic plaque initiation and progression. However, changes in the activation state of circulating monocytes, the main components of the innate immunity, may precede the local events.
