Special Issue Information

Dear Colleagues,

Cardiovascular disease (CVD) remains a leading cause of global morbidity and mortality, with genetic and molecular factors playing pivotal roles in its development, progression, and treatment. Advances in genomics, transcriptomics, and epigenetics have revealed novel pathways and biomarkers, offering unprecedented opportunities in precision medicine. This Special Issue, "Genetic and Molecular Insights into Cardiovascular Disease: From Mechanisms to Precision Medicine", will showcase cutting-edge research and reviews exploring the genetic and molecular basis of CVD. Topics of interest include, but are not limited to, the following:

  • Genetic variants and pathways driving CVD risk and outcomes;
  • Epigenetic modifications (e.g., DNA methylation, histone modifications) in CVD pathogenesis;
  • The role of non-coding RNAs (e.g., miRNAs, lncRNAs) in cardiovascular biology;
  • Integration of polygenic risk scores (PRSs) and Mendelian randomization (MR) for causal inference and risk prediction;
  • Translational applications of genetic and molecular diagnostics in personalized CVD management (e.g., the sex gap in CVD).

We welcome original research articles, reviews, and perspectives exploring the genetic and molecular mechanisms behind CVD and their implications for precision medicine. This Special Issue will provide a platform for researchers to share insights into the genetic architecture of CVD and its potential in transforming clinical practice.

Background: The most common form of monogenic diabetes is maturity onset diabetes of the young (MODY). This study investigates the molecular basis of MODY type 2 (GCK-MODY) in a group of Italian patients, focusing on the functional characterization of a synonymous variant, c.579G>T (p.Gly193Gly), in the glucokinase gene (GCK). Methods: Clinical evaluation and genetic analysis, including whole exome sequencing and Sanger sequencing, were used to identify the variant in GCK, then functional studies using a minigene approach allowed the functional characterization. Results: This study identified the synonymous variant, along with a nonsense mutation, c.859C>T (p.Gln287Ter), in GCK in two Italian patients. Minigene approach demonstrated that the synonymous variant disrupts splicing at the exon 5 boundary, leading to a frameshift and premature stop codon. Similarly, the nonsense mutation also altered splicing, exacerbating the molecular defect. Conclusions: These findings highlight the importance of functional assays, particularly minigene studies, in interpreting the pathogenicity of synonymous and nonsense variants, especially in genes like GCK where splicing alterations can significantly impact protein function. This study underscores the clinical utility of targeted genetic screening for personalized diabetes management. Full article

Background: Cholesterol imbalances and elevated blood pressure (BP) are closely interrelated risk factors for cardiovascular disease (CVD) and are subject to genetic influences. We sought to identify novel associations between candidate genetic coding variants and CVD traits in our isolated study cohort and validate them in a general population cohort. Methods: We leveraged the population genetic features of the Norfolk Island Health Study (NIHS, n = 601), to identify candidate functional variants which were analysed for association with CVD and metabolic syndrome traits. We followed up suggestive variant-trait associations in the 2022 release of UK Biobank whole exome data (n = 200,625). Results: We identified a novel ten-base-pair in-frame missense multi-nucleotide variant (MNV), tagged by rs35724886, in the lipid metabolism gene ACOT4, which was associated with cholesterol levels and blood pressure. The MNV was associated with a lower incidence of ‘elevated BP’—systolic BP ≥ 130 mmHg or diastolic BP ≥ 80 mmHg—(OR: 0.70; 95% CI: 0.51, 0.97; p = 0.03), and higher total cholesterol levels (β = 0.08; p = 0.04) in the NIHS. Validation in the UK Biobank revealed consistent associations between the MNV (proxied by rs35725886) and lower incidence of ‘elevated BP’ (p = 0.0001), higher total cholesterol (p = 0.01), and reduced use of medication for managing blood pressure (p = 1.8 × 10−6) and cholesterol (p = 0.002). Structural modelling and in-silico predictions suggested that the MNV introduced destabilising changes in the ACOT4 protein, likely influencing peroxisomal lipid metabolism pathways critical to CVD risk. Conclusions: This study identified a coding MNV with potential implications for understanding the genetic regulation of lipid metabolism and its impact on cardiovascular health. Full article

Background: The monocarboxylate transporter 1 (MCT1) plays a central role in myocardial lactate handling and metabolic adaptation. The functional rs1049434 polymorphism (T1470A; Asp490Glu) affects MCT1-mediated lactate transport and substrate utilization, but its clinical relevance in sarcomere-related hypertrophic cardiomyopathy (HCM) remains poorly defined. Methods: We studied 56 carriers of pathogenic or likely pathogenic sarcomeric variants examined in a familial HCM program. All participants underwent standardized clinical phenotyping, including electrocardiography, transthoracic echocardiography, and cardiac magnetic resonance imaging. Genotyping of MCT1 rs1049434 was performed on genomic DNA. Analyses focused on sex-stratified genotype distribution, phenotypic expression among the 26 individuals who fulfilled diagnostic criteria for HCM, and the influence of habitual vigorous exercise. Septal wall thickness was the primary structural endpoint. Results: Among the 26 patients with established HCM (10 women, 16 men), a marked sex-specific effect emerged. Female carriers of the T-allele (TT/TA) exhibited significantly greater interventricular septal thickness compared with AA homozygotes (23.2 vs. 14.2 mm; p = 0.037). In men, septal thickness did not differ by genotype. However, male patients engaged in vigorous physical activity showed a consistently milder structural phenotype, including lower septal thickness (18.3 vs. 19.9 mm; p = 0.585) and directionally favorable markers of mechanical severity. Phenotypic distribution was predominantly asymmetric septal hypertrophy in both sexes, without genotype-dependent differences. Conclusions: The phenotypic impact of MCT1 rs1049434 in sarcomere-positive HCM is context-dependent. In women, impaired monocarboxylate handling is associated with greater hypertrophic remodeling, whereas in men, exercise-related metabolic conditioning appears to attenuate disease severity. These findings support a genotype–sex–environment interaction relevant to precision medicine approaches in HCM. Full article

Background/Objectives. Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and represents a major public health problem. Genetic factors contribute to AF susceptibility, including variants associated with atrial remodeling. Methods. This case–control study investigated the rs3903239 polymorphism of the PRRX1 gene in a Kazakh population. The main group included patients with AF (n = 75), the control group consisted of 2 subgroups: subgroup 1 (control group 1) included conditionally healthy patients (n = 73), subgroup 2 (control group 2) consisted of patients with arterial hypertension (AH) and coronary heart disease (CHD) without diagnosed AF at the time of inclusion in the study (n = 50). Genotype and allele frequencies were compared between patients with AF and two control groups. The frequency of the rs3903239 polymorphism genotypes of the PRRX1 gene in the main group and in the control groups was in the Hardy–Weinberg equilibrium. Results. The frequency of the rare G allele (AG + GG genotypes) was higher in patients with AF compared with conditionally healthy controls; however, this difference did not reach statistical significance (OR 1.357; 95% CI 0.845–2.178). Conclusions. The observed differences represent a non-significant trend and do not demonstrate a statistically confirmed association between the rs3903239 polymorphism of the PRRX1 gene and AF in the Kazakh population.
