We aimed to scrutinize the extent to which single amino acid substitutions in the MTHFR and factor V Leiden (FVL) genes affect the risk of gestational diabetes mellitus (GDM) in pregnant women of South Indian descendant. This case-control study was implemented once the ethical approval has been obtained. Overall, 237 women were recruited in this study: 137 had been diagnosed with GDM and the remaining 100 women were used as normal controls or non-GDM. The diagnosis of GDM was confirmed with biochemical analysis, i.e., GCT and oral glucose tolerance tests. Five milliliters of peripheral blood was collected and used for biochemical and molecular analyses. DNA was isolated, and genotyping for MTHFR (C677T) and FVL (G1691A) mutations was performed using PCR-RFLP. FVL (G1691A) locus was not polymorphic in the investigated sample. There was no significant difference in the allele and genotype frequencies of C677T polymorphism between GDM and non-GDM women (p = 0.8892).

Background: Thrombophilia, characterized by an increased risk of thrombosis, can result from genetic polymorphisms in clotting factors. This study aims to investigate the prevalence of factor V Leiden (G1691A), factor II prothrombin (G20210A), and MTHFR (C677T and A1298C) polymorphisms in a Greek population, evaluating not only their association with thrombophilia, but also broader health implications.
Methods: We conducted a cross-sectional study involving one hundred apparently healthy adults from Thessaloniki, Greece.

Article Synopsis
- - This study examined how genetic thrombophilia affects early versus late pregnancy loss in 156 women, dividing them into two groups based on when they experienced miscarriage.
- - Key genetic mutations were identified as risk factors for pregnancy loss, with certain combinations, like Factor V Leiden and MTHFR mutations, showing significant interactions linked to early loss.
- - Various mutations had different odds ratios indicating their risk levels, with some being more associated with early pregnancy loss (like PAI-1 4G/5G) and others (like MTHFR A1298C) linked to late pregnancy loss.
Laboratory Testing for Activated Protein C Resistance (APCR): An Update.

Activated protein C resistance (APCR) reflects a hemostatic state defined by a reduced ability of activated protein C (APC) to affect an anticoagulant response. This state of hemostatic imbalance is characterized by a heightened risk of venous thromboembolism. Protein C is an endogenous anticoagulant that is produced by the hepatocytes and undergoes proteolysis-mediated activation to APC.

Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by the persistent presence of antiphospholipid antibodies (aPL) and thrombotic or obstetric events. Given the heterogeneity of the clinical manifestations, it is likely that genetic and acquired factors are involved in the pathogenesis of APS. The inherited polymorphisms of the thrombophilic gene, including methylenetetrahydrofolate reductase (MTHFR) C677T, type 1 plasminogen activator inhibitor (PAI-1) 4G/5G, factor V Leiden (FVL) G1691A, prothrombin (PT) G20210A, antithrombin (AT), and fibrinogen (Fg) polymorphisms, were analyzed in 67 aPL(+) patients from the Chinese Han population, including 41 APS patients and 26 persistent aPL carriers.

Background: Venous thromboembolism (VTE) is a life-threatening cardiovascular syndrome that characterized by the imbalance of hemostasis and thrombosis and the formation of thrombi in the blood vessels. The aim of this study was to elucidate the clinical impact of the PAI-1 4G/5G polymorphism in Chinese patients with VTE.
Methods: A total of 169 subjects (89 VTE, 10 hyperbilirubinemia, 10 hyperlipidemia and 60 healthy controls) were recruited at Peking Union Medical College Hospital.
