Insights

Genetic variations in endothelial nitric oxide synthase (eNOS) are linked to ischemic stroke risk in young adults. The eNOS 4ab variant specifically emerged as a significant risk factor in a Chinese population study.

Area of Science:

  • Genetics
  • Neurology
  • Cardiovascular Science

Background:

  • Ischemic stroke mechanisms in young adults remain unclear.
  • Investigating genetic predispositions is crucial for understanding young adult stroke.
  • Focus on genes related to hemostasis, homocysteine metabolism, and endothelial function.

Purpose of the Study:

  • To identify genetic risk factors for ischemic stroke in young adults.
  • To assess the prevalence of specific gene variants in a young stroke patient cohort.
  • To compare genetic profiles of young stroke patients with age- and gender-matched controls.

Main Methods:

  • Case-control study involving 97 young adult ischemic stroke patients (<45 years).
  • Analysis of factor V Leiden, MTHFR C677T, and eNOS 4ab gene variants.
  • Comparison with 99 age- and gender-matched healthy controls.

Main Results:

  • No significant difference in MTHFR C677T genotype frequencies between patients and controls.
  • Factor V Leiden variant was absent in both groups.
  • A statistically significant higher prevalence of the eNOS 4bb genotype was observed in stroke patients (92.8%) compared to controls (81.8%).

Conclusions:

  • The eNOS 4ab gene variant is a potential risk factor for ischemic stroke in young adults.
  • Endothelial function, influenced by eNOS, plays a role in young stroke pathogenesis.
  • Further research is warranted to elucidate the role of eNOS variants in ischemic stroke.

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Principles of Pharmacogenetics: Types of Genetic Variants

The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
