A synergic effect between CYP2C19*2, CYP2C19*3 loss-of-function and CYP2C19*17 gain-of-function alleles is associated with Clopidogrel resistance among Moroccan Acute Coronary Syndromes patients.

Objective: The main objective of our study was to investigate the association of CYP2C19*2 and CYP2C19*3 loss-of-function and CYP2C19*17 gain-of-function variants of CYP2C19 gene with Clopidogrel resistance in a sample of Moroccan Acute Coronary Syndromes patients.

Results: Our results showed the existence of a synergic effect between the three alleles, statistically very significant, on Clopidogrel resistance among the treated patients (P = 0.0033).

Impact of I/D polymorphism of angiotensin-converting enzyme (ACE) gene on myocardial infarction susceptibility among young Moroccan patients.

Objective: Our case-control study aimed to access the potential association of insertion/deletion (I/D) ACE (angiotensin converting enzyme) gene polymorphism with myocardial infarction (MI) risk of occurrence among a sample of Moroccan patients, especially young ones.

Results: Distribution of I/D ACE gene variant among cases vs controls, showed that healthy controls carried out higher frequency of wild type allele I compared to cases (23.5% vs 21.

Does i-T744C P2Y12 Polymorphism Modulate Clopidogrel Response among Moroccan Acute Coronary Syndromes Patients?

An interindividual variability in response to Clopidogrel has been widely described in patients with acute coronary syndromes (ACS). The contribution of genetics on modulating this response was widely discussed. The objective of our study was to investigate the potential effect of i-T744C P2Y12 polymorphism on Clopidogrel response in a sample of Moroccan ACS patients.

G2691A and C2491T mutations of factor V gene and pre-disposition to myocardial infarction in Morocco.

Coagulation factor Leiden mutation has been described as a common genetic risk factor for venous thrombosis; however, this mutation was reported to be practically absent in an African population. Recently, a novel non-sense mutation in the gene encoding factor V has been associated with the risk of occurrence of cardio-cerebrovascular diseases such as stroke and venous thrombosis. The aim of the present study was to investigate whether the factor V Leiden (FVL) and C2491T non-sense mutations are associated with the risk of developing myocardial infarction.

Genetic polymorphisms of T-1131C APOA5 and ALOX5AP SG13S114 with the susceptibility of ischaemic stroke in Morocco.

Ischaemic stroke is a multifactorial disease. Genetic polymorphisms involved in lipid, inflammatory and thrombotic metabolisms play an important role in the development of ischaemic stroke. The present study aimed to assess the relationship between T1131C APOA5 and SG13S114 ALOX5AP polymorphisms and the risk of ischemic stroke in 175 cases and 201 controls.

Association of G894T eNOS, 4G/5G PAI and T1131C APOA5 polymorphisms with susceptibility to myocardial infarction in Morocco.

Background: Myocardial infarction (MI) is a common multifactorial disease. Numerous studies have found that genetic plays an essential role in MI occurrence. The main objective of our case-control study is to explore the association of G894T eNOS (rs1799983), 4G/5G PAI (rs1799889) and T1131C APOA5 (rs662799) polymorphisms with MI susceptibility in the Moroccan population.
