Objective:
To identify associations or interrelations between carriage of the methylenetetrahydrofolate reductase (MTHFR) C677T, the MTHFR A1298C, the factor V Leiden G1691A, the factor II prothrombin G20210A, the human platelet antigen (HPA) 1 C12548T, and the apolipoprotein (APO) B R3500Q polymorphisms and idiopathic recurrent miscarriage (IRM).
Design:
Prospective case control study.
Setting:
Academic research institution.
Patient(S):
One hundred forty-five women with a history of three or more consecutive pregnancy losses before 20 weeks gestation and 101 healthy postmenopausal women with at least two live births and no history of pregnancy loss.
Intervention(S):
Peripheral venous punctures.
Main Outcome Measure(S):
Multiplex polymerase chain reaction was performed to identify the different alleles of six candidate genetic risk factors for IRM (MTHFR C677T, MTHFR A1298C, factor V Leiden G1691A, factor II prothrombin G20210A, HPA 1 C12548T, and the APO B R3500Q).
Result(S):
Allele and genotype frequencies of all polymorphisms were not significantly different between the study and the control groups. Also, no significant associations occurred between combinations of polymorphisms and the occurrence of IRM.
Conclusion(S):
Our data fall short of showing any significant association between single polymorphisms of the MTHFR, the Factor V Leiden, the Factor II Prothrombin, the HPA 1 and APO B genes or combinations of these polymorphisms and the occurrence of IRM.
