We conclude that in subjects attending a metabolic ward, homozygosity for a deletion polymorphism of the ACE gene consistently discriminates subjects with a stroke history.
The preliminary results of the present study failed to confirm our hypothesis that ACE gene polymorphism is a cardiovascular risk factor in children of parents with premature stroke.
We conclude that determination of the carotid IMT and of the ACE I/D polymorphism do not permit discrimination of the cardiovascular risk in children of parents with or without premature stroke.
The aim of this replication study was to confirm our previous findings of associations between the TNF(-308) G/A, IL4R 503 S/P, and ADRB2 27 Q/E polymorphisms and large vessel stroke risk.
The frequencies of the different genotypes for the Leiden V mutation and ACE I/D polymorphism in the 3 subgroups of stroke were compared with 199 stroke-free control subjects whose MRI findings were normal.
This lack of association between stroke and ACE I/D polymorphism did not change in the presence of traditional risk factors (hypertension, diabetes mellitus, smoking, and dyslipidemia).
Following multivariate adjustment, carriers of the TNF-alpha (-308)A allele, the IL-1-RA 2* allele or the IL-6 (-174)C allele appeared to have an increased risk of stroke in association with a febrile episode prior to strokes.
The authors conducted a population-based, case-control study at Group Health (Seattle, Washington) between 1995 and 1999 to determine whether common haplotypes in the angiotensinogen gene (AGT), the renin gene, the angiotensin-converting enzyme gene, and the angiotensin II receptor type 1 and receptor type 2 genes were associated with the risk of myocardial infarction and stroke among pharmacologically treated hypertensive patients.
The deletion polymorphism in the angiotensin-converting enzyme gene is a new independent risk factor for lacunar stroke but is not a risk factor for stroke associated with carotid stenosis.
We investigated the association between ACE genotype and the incidence of stroke in a large, prospective, matched case-control sample from the Physicians' Health Study.
This study was designed to detect wether the TNF2 allele is associated with disease progression in MS. We examined the TNFalpha -308 polymorphism with an allelic discrimination PCR to detect the G-->A transition in the genomic DNA of 283 MS patients from Germany and in 72 patients with amyotrophic lateral sclerosis (ALS) and 66 with stroke from the same genetic background who served as controls.
The ACE genotype was not associated with the long-term risks of stroke, cardiac events, mortality, dementia, or cognitive decline; neither did the ACE genotype predict the blood pressure reduction associated with the use of the ACE inhibitor perindopril.
The combination of TNF (-308)GG homozygosity and the IL4R 503P variant carrier status was associated with a particularly strong predisposition to LV stroke (odds ratio [OR] = 5.5; 95% confidence interval [CI] = 2.3-13.1).
The aim of this study was to evaluate whether the ACE I/D genotype is associated with stenosis of extracranial arteries and stroke in middle-aged and aged men and women.
There was also no significant difference for ACE genotype distribution and allelic frequency within the stroke group classified according to Bamford criteria (chi2 = 4.827; df = 3; p = 0.185).
The ACE D allele prevalence was also greater among patients reporting a parental history of stroke incidence before age 65 years (0.66 versus 0.57, P = 0.05).
The Objective of this research was to study the relationship of angiotensin converting enzyme (ACE) genotype with serum triglycerides concentration in stroke patients.
