Background: Coronary artery disease (CAD) is characterized by narrowing/ blockade of coronary arteries that is mainly caused by atherosclerotic plaques. Considering the involvement of platelet abnormalities, such as defective aggregation and adhesion, in the cardiovascular-related disorders, genetic variations in human platelet alloantigens (HPA) have been implicated in the CAD susceptibility. Herein, we intended to determine the association of HPA-1 to -6, -9, and -15 biallelic polymorphisms with CAD in an Iranian population.
Methods: In this retrospective case-control study, 200 CAD subjects and 100 matched healthy individuals were enrolled. DNA samples were isolated from peripheral blood samples and genotyping of HPA polymorphisms was accomplished using polymerase chain reaction-sequence-specific primers.
Results: The alleles and genotypes of studied HPA polymorphisms were equally distributed among cases and controls and therefore no statistically significant differences were detected. Univariate analysis identified no association of combined haplotypes with CAD risk. However, multivariate analysis showed a positive association of the HPA1b/2a/3b haplotype with CAD after adjustment for some covariates (including BMI, TG, LDL, FBS and blood pressure) that conferred a CAD susceptibility haplotype (P = 0.015; OR = 2.792; 95% CI 1.45-8.59).
Conclusions: Although alleles, genotypes, and haplotypes of HPA polymorphisms were not associated with CAD risk, HPA1b/2a/3b haplotype was found to be a dependent disease risk haplotype in Iranian population after correcting for confounding factors.

The role of GTF2I (General Transcription Factor2I) alteration has already been reported in thymic cancer as a valuable biomarker. However, the association of GTF2I mutation with renal cancer for prognosis of immunotherapy is not yet examined. The biologic and oncologic significance of GTF2I in renal cancer was examined at multiomics level such as mutation, copy number alteration, structural variants.

Article Synopsis
- - Polycystic ovary syndrome (PCOS) is a common hormonal disorder in women, influenced by genetic and environmental factors, especially connected to the hypothalamic-pituitary-adrenal (HPA) axis genes.
- - A study investigated various single nucleotide polymorphisms (SNPs) in five melanocortin receptor genes within 212 Italian families with PCOS, finding significant associations with certain SNPs in MC1R, MC2R, MC3R, and MC5R.
- - This research highlights the role of specific melanocortin receptor genes in PCOS, marking a new connection, while emphasizing the need for further functional studies to confirm these findings.

Objectives: To explore a causal relationship between ferroptosis-related gene heat shock protein A5 (HSPA5) and hepatocellular carcinoma (HCC).
Methods: A two-sample Mendelian randomization (MR) design was employed to evaluate the causal relationships among HSPA5, regulatory T cells (Tregs), and HCC. Single nucleotide polymorphisms (SNPs) associated with HSPA5, Tregs and HCC were selected as instrumental variables through publicly available genome-wide association studies (GWAS) databases.

Article Synopsis
- The study focused on finding a better way to identify human leucocyte antigens (HLA) and human platelet antigens (HPA) in blood donors.
- Researchers tested 268 platelet donors using a special long-read sequencing method to see their genetic makeup and how common different alleles are.
- They discovered new genetic variations in several HPA systems and established a new technique that can help create a better blood platelet donor bank.

Prior work consistently links additive genetic variation in the hypothalamic-pituitary-adrenal (HPA) axis-a multilocus genetic profile score (MGPS)-to depression risk in the context of stress exposure. However, despite that HPA MGPS variants were selected based on evidence that they elevate cortisol reactivity, there are surprisingly few tests of whether an HPA MGPS elevates cortisol reactivity to lab-based stress. Similarly, despite neurobiological connections and coordination between the HPA axis and the sympathetic nervous system (e.
