Background: Polycystic ovary syndrome (PCOS) is a common reproductive disorder. Obesity, which is linked with lower adiponectin levels, increases a woman's risk of developing PCOS; however, the association between adiponectin and PCOS is controversial. Adiponectin levels could be affected by single nucleotide polymorphisms (SNPs) in the ADIPOQ gene. This study aimed to test the relationship between serum adiponectin and PCOS in Jordan and the association between the rs2241766, rs1501299, and rs266729 SNPs in the ADIPOQ gene and PCOS...

Polycystic ovary syndrome (PCOS) is a complex endocrine-metabolic disease. Previous studies indicate that genes GGT1 and HNF1A may contribute to the abnormal glucose metabolism and altered lipid profile that are important clinical features of PCOS. In the current study, the correlation between polymorphisms in the GGT1 and HNF1A genes and PCOS was explored. A total of 310 family trios were studied and the transmission disequilibrium test (TDT) was used to assess the linkage between PCOS and three single-nucleotide polymorphisms (SNP) (rs4820599 of GGT1, rs7305618 and rs2393791 of HNF1A)...

Dyslipidemia is one of the common metabolic disorders in Polycystic Ovary Syndrome (PCOS). Proprotein convertase subtilisin kexin type 9 (PCSK9) is a new component of lipid metabolism and correlated to the development of dyslipidemia and atherosclerosis. This protein acts by preventing the recycling of LDL receptors (LDL-r) back to the cell surface and thus generates higher levels of LDLc. The objective of this study was to evaluate the PCSK9 polymorphisms rs505151 (c.2009A>G), rs562556 (c.1420A>G) and rs11206510 (T>C) and plasma PCSK9 levels in PCOS...

BACKGROUND: Genetic factors are believed to play an important role in the etiology of polycystic ovarian syndrome (PCOS) which is the most common endocrinological disorder of women in their reproductive age. Androgen metabolism is impaired in PCOS and, thus, CYP19 gene which is involved in this pathway can be a candidate gene. Previous studies have shown a relationship between single nucleotide polymorphism (SNP) of CYP19 in hyperandrogenism and PCOS in some racial groups. OBJECTIVE: This study was designed to elucidate the role of CYP19 gene in PCOS in Iran...

Vitamin D deficiency has been related to metabolic syndrome (MetS) in polycystic ovary syndrome (PCOS). The vitamin D-binding protein (DBP) is the main protein involved in vitamin D transport. Two single-nucleotide polymorphisms (SNPs) of the DBP gene, rs4588 and rs7041, have been associated with low circulating levels of 25-hydroxyvitamin D [25(OH)D] in various populations, but not in women with PCOS. Therefore, we determined the genotype and haplotype distribution of DBP gene polymorphisms and investigated the associations between these genetic variants and their haplotypes with PCOS, MetS, and 25(OH)D levels in women with PCOS and controls from the South of Brazil...
