Inherited Thrombophilia in a Lebanese Family of Four Generations: A Case Report of Recurrent Miscarriage

Investigation of the relationship between inherited thrombophilia and novel coronavirus pneumonia

Aim: This study aimed to investigate the relationship between severe novel coronavirus pneumonia (NCP) and hypercoagulable conditions that predispose patients to thrombosis such as the prothrombin gene ( F2) rs1799963 (G20210A), factor V Leiden ( F5) rs6025 (G1691A) and PAI-1 (rs1799768). Patients: NCP-diagnosed 62 previously healthy patients were enrolled for the investigation of the thrombophilia-related polymorphisms. Materials & methods: The frequency of genotypes were compared with healthy control group frequencies from other studies. Results: There were no statistically significant differences between the severe patient group and the healthy population regarding the investigated single nucleotide polymorphisms (SNPs). Conclusion: This study is the first to rule out the relationship of rs1799963, rs6025 and rs1799768 with severe NCP.

Association of venous thromboembolism and myocardial infarction with Factor V Leiden and Factor II gene mutations among Libyan patients

Factor V Leiden G1691A (FVL) and Factor II prothrombin G20210A (PGM) mutations are the leading causes of thrombophilia. In this study, we have investigated the prevalence of the FVL G1691A and PGM G20210A single nucleotide polymorphisms (SNPs) among Libyan deep vein thrombosis (DVT) and myocardial infarction (MI) patients. SNP genotyping was performed using high-resolution melt analysis (HRM) and DNA sequencing. Biochemical parameters conducted on 112 males and 93 females showed no significant difference in means between the control group and the deep vein thrombosis and myocardial infarction groups. For Factor V Leiden, 40 samples were genotyped. Of the 40 samples, 6 (15.0%) of them were heterozygous and no one was homozygous. As for Factor II SNP, 59 samples were genotyped and only 2 (3.3%) were heterozygous. All the heterozygous samples showed 100% concordance between the HRM-PCR and DNA sequence analysis. Our study showed, for the first time, that both the FVL and PGM mutations are present among Libyan DVT and MI patients and that the FVL mutation is significantly associated with DVT but not with MI. However, our results do not support the association of PGM G20210A mutation with DVT or MI.
