In young patients with T1D, neurological manifestations of cerebral hypertension should suggest the possibility of a cerebral venous sinus thrombosis (CVST). In these patients an inherited prothrombotic risk factor, including factor V Leiden G1691A gene mutation, should be considered during an event of thrombosis. Improving the glycemic control is the first factor that should be controlled in a...

The combination of thrombophilia and pregnancy increases the risk of thrombosis and the potential for adverse outcomes during pregnancy. The most significant common inherited risk factor for thrombophilia is activated protein C resistance (APCR), a poor anticoagulant response of APC in haemostasis, which is mainly caused by an inherited single-nucleotide polymorphism (SNP), factor V G1691A (FV ...

The levels of antibodies to cardiolipin and β2-glycoprotein I and polymorphic variants G1691A of Factor V (factor V Leiden, FVL) and G20210A of prothrombin gene (G20210A) were studied in 16 patients with upper-extremity deep vein thrombosis (UEDVT). Most of patients with this syndrome have elevated values of these antibodies. Two of these patients are heterozygous carriers for G20210A and 1 - f...

OBJECTIVES To evaluate the performance of a Russell viper venom-based activated protein C resistance (APCR) screening test relative to DNA analysis for the factor V Leiden mutation. METHODS We evaluated the concordance between Pefakit APCR screening results and DNA analysis for 435 patients homozygous (n = 11), heterozygous (n = 310), or wild-type (n =114) for the G1691A allele. RESULTS Usi...

A nucleic acid photocross-linking technology was used in the development of a direct assay for factor V Leiden, a point mutation in the factor V gene (G1691A) that is the most common inherited risk factor for thrombosis. This cross-linking hybridization assay included two allele-specific capture probes and six signal-generating reporter probes; all were modified with a photoactivated cross-link...

Introduction: Recurrent pregnancy loss (RPL) is defined as two or more consecutive which occurs before the 20th weeks of pregnancies for last menstrual period. Hereditary cause thrombophilic gene mutations and polymorphism may play an essential role in RPLs. Material Method: 291 women with a history abortions study group 61 without miscarriages control were included study. In this we analysed e...

Objective: The pathogenesis of human spontaneous abortion involves a complex interaction several genetic and environmental factors. Resistance to anticoagulant activity activated protein C (APC), often due point mutations in Factor V gene. Leiden mutation is definitely associated with pregnancy complications. In this study, we have investigated association factor recurrent miscarriage Iranian p...
