Special Issue Information

Dear Colleagues,

This Special Issue is a continuation of our previous Special Issue, “Genes and Human Diseases 2.0”. The study of the causes and mechanisms of human disease development, despite the numerous works carried out in this field, continues to be the focus of attention of various scientific research teams. The essential role of genetic factors in the formation of the vast majority of human diseases is beyond doubt. At the same time, despite the substantial accumulated factual material on this theme, there is no complete and definitive understanding of the pathogenetics of most human diseases at the moment. Often, the data obtained are not confirmed in subsequent studies, and in some cases, they are contradictory. It is necessary to continue further genetic-epidemiological studies in order to establish genetic factors that determine the susceptibility to various human diseases in different ethnic and territorial groups. Obtaining new data on the contribution of genetic factors to the formation of human diseases and the role of gene–gene and gene–environment interactions affecting the risk of developing diseases will significantly advance our understanding of the pathogenetics of diseases. Ultimately, this will create prerequisites for the use of candidate genes as effective biomarkers in practical medicine.This Special Issue will compile new data on the role of genetic factors in the formation of different human diseases to better-understand the genetic and molecular mechanisms of human disorder development.

Neurotrophic factors are regulatory proteins of nervous tissue. They have a significant effect on all processes in neurons. Neurotrophic factors participate in the processes of neuronal differentiation, neurogenesis, synaptogenesis, and the regulation of neuronal plasticity. Numerous data in the literature indicate that disruption of the regulation of neurotrophic factors can play an important role in the etiology of affective disorders. We examined 235 patients with an affective disorder (F31, F32, F33, F34.1, ICD-10) and 187 healthy controls. The mental state of the patients was assessed by SIGH-SAD, HARS, and CGI scales. Genotyping of polymorphic variants of neurotrophic factor genes (BDNF, NGF, and NRG1) was performed using real-time PCR. Only one of the polymorphisms (rs7124442 in the BDNF gene) showed an association with the affective disorders. All polymorphisms (except rs11030104 in the BDNF gene) showed an association or associated trend with clinical characteristics of the disease, evaluated according to psychometric scales and response to therapy. Our results support the potential value of the studied neurotrophic genes as a neurobiological marker for depression pathogenesis, clinical characteristics, and response to treatment. Due to several limitations, further case–control studies with larger sample sizes and different ethnic groups are needed. Full article

Since 2023, the Russian Federation (RF) has implemented an expanded newborn screening (NBS) program for 36 hereditary disorders, which now includes 5q spinal muscular atrophy (5q SMA). As a result of newborn screening for 5q SMA conducted in the RF during 2023–2024, 288 newborns with a homozygous deletion of exon 7 in the SMN1 gene were identified by molecular genetic methods. The overall observed incidence of 5q SMA was 1 in 8439 newborns, which does not significantly differ from the expected incidence of 1 in 7953 newborns, established by previous pilot screening projects (p > 0.05). A comparison of the genotypes of patients identified through selective and newborn screening showed statistically significant differences in the proportions of patients carrying two, three, and four or more copies of the SMN2 gene. These findings demonstrate that the NBS program is effective in detecting both individuals with more severe phenotypes, as expected, and those with milder forms of the disease. Full article

Familial dysbetalipoproteinemia (FD) is a prevalent and highly atherogenic hyperlipoproteinemia associated with the ε2/ε2 APOE genotype or rare APOE variants. The contributions of additional genetic and clinical factors to the FD phenotype remain unclear. We investigated these factors in both autosomal recessive and autosomal dominant forms of FD. Targeted (n = 4666) and exome (n = 194) sequencing were used to identify the ε2/ε2 APOE genotype or rare FD-causative APOE variants. Twenty-four lipid-related genes and forty variants included in a polygenic risk score for hypertriglyceridemia (HTG) were analyzed. FD was defined by the presence of FD variants and triglycerides (TG) ≥ 1.5 mmol/L (main study group). The comparison group consisted of patients with FD variants but TG < 1.5 mmol/L. Univariable and multivariable regression analyses were performed. A total of 71 unrelated subjects were identified (45.1% male, median age 50 years). FD was diagnosed in 52 patients, while 19 had FD variants only. Age (p = 0.019), elevated polygenic risk for HTG (p = 0.001), and the presence of metabolic syndrome components (p = 0.014) were independently associated with the FD phenotype. TG levels were significantly associated with polygenic burden (0.05 mmol/L per percentile), the presence of additional rare lipid-related variants (7.0 mmol/L), and glucose metabolism disorders (3.62 mmol/L), together explaining 30% of TG variance in cross-validated model. These results highlight the interplay of genetic and metabolic factors in FD development and support the integration of HTG genetic risk scores and metabolic control into personalized FD management.

Atherosclerosis is a complex disease characterized by pathological thickening of the arterial intima. The mechanisms underlying the induction and progression of atherosclerosis are convoluted and remain under active investigation, with key components such as lipid accumulation and local inflammation being identified. Several risk factors (e.g., metabolic disorders, genetic background, diet, infections) have been shown to exacerbate disease progression, but their roles as clinically relevant markers remain to be established. Despite the growing body of evidence on the molecular pathogenesis of atherosclerosis, there is no effective preventive treatment against the development of this disease. In this review, we focus on gene targets for gene therapy as a novel potential approach to cure and prevent atherosclerosis. We critically review recent research demonstrating the therapeutic potential of viral vector-based (adeno-associated virus (AAV) and lentivirus) gene therapy for the treatment of atherosclerosis. We also summarize alternative gene targets and approaches (e.g., non-coding RNA (ncRNA), micro RNA (miRNA), small interfering RNA (siRNA), antisense oligonucleotide (ASO), CRISPR/Cas9) that aim to limit disease progression. We highlight the importance of local inflammation in the pathogenesis of atherosclerosis and propose gene targets with anti-inflammatory activity to inhibit the pathological inflammatory response. In addition, we provide perspectives on the future development of gene therapeutics and their potential applications. We anticipate that recent advances in gene therapy will help to identify new and effective targets to prevent atherosclerosis. Full article
