Background: The relationship between CYP17A1 genetic polymorphisms and coronary artery disease (CAD) remains unclear. The aim of the present study was to assess the association between CYP17A1 gene polymorphism and CAD in a Chinese Uygur population.
Methods: A total of 493 people including 266 patients and 227 controls were selected for the present study. All CAD patients and controls were genotyped for the same five single nucleotide polymorphisms (SNPs) (rs4919686, rs1004467, rs4919687, rs10786712, and rs2486758) by a real-time PCR method.
Results: The rs4919686, rs1004467, and rs4919687 polymorphisms were found to be associated with CAD in genotypes, dominant model, recessive model, and allele frequency (rs4919686: all p<0.05, rs1004467: all p ≤ 0.001, rs4919687: all p<0.001); the significant difference was retained (all p<0.05) after adjustment for the major confounding factors. The overall distribution of haplotypes established by SNP1-SNP4 (in total subjects and men) and SNP1-SNP4-SNP5 (in total subjects) were significantly different between the CAD patients and the control subjects (p=0.006, men: p=0.026, and p=0.030, respectively).
Conclusion: Polymorphisms rs4919686, rs4919687 and rs1004467 were found to be associated with CAD in this Uygur population.

Background: 17α-Hydroxylase/17,20-lyase deficiency (17OHD) is a rare form of congenital adrenal hyperplasia (CAH), caused by mutations in the CYP17A1 gene. It typically manifests clinically as variable degree of hypertension, hypokalemia, and disorders of sexual development (DSD), which can include abnormal sexual differentiation in males and sexual infantilism in females. Over 100 mutations in CYP17A1 have been identified, with most cases involving missense mutations or small deletions.

Background: Endocrine-disrupting chemicals (EDCs) interfere with the endocrine system and negatively impact reproductive health. Biochanin A (BCA), an isoflavone with anti-inflammatory and estrogen-like properties, has been identified as one such EDC. This study investigates the effects of BCA on transcription, metabolism, and hormone regulation in primary human granulosa cells (GCs), with a specific focus on the activation of bitter taste receptors (TAS2Rs).

Differences of sex development (DSD) refer to various congenital conditions affecting the urogenital and hormonal systems. Accurate diagnosis and personalized management are crucial for supporting patients through complex decisions, such as those related to gender identity. This study represents the first comprehensive investigation into DSD in Iran, analyzing patient's clinical and genetic data between 1991 and 2020.

Leydig cells produce hormones that are required for male development, fertility, and health. Two Leydig cell populations produce these hormones but at different times during development: fetal Leydig cells, which are active during fetal life, and adult Leydig cells, which are functional postnatally. Historically, our ability to understand the origin and function of Leydig cells has been made difficult by the lack of genetic models to exclusively target these cells.

Purpose: This study aimed to investigate the genetic etiology in an infertile patient presenting with consistently elevated progesterone levels.
Methods: Genomic DNA was extracted from the patient's blood sample and subjected to whole-genome sequencing (NGS) using the Illumina NovaSeq platform. Bioinformatic analyses were conducted to identify single nucleotide variants (SNVs) and insertion-deletion mutations (Indels) potentially associated with the patient's clinical phenotype.
