Human Genetics

1.3K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Epistasis Analysis01:09

Epistasis Analysis

5.6K
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...

Single Nucleotide Polymorphisms-SNPs

17.7K
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,...

Comparing Copy Number Variations and SNPs

18.5K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Psychoneuroimmunology: Cardiovascular Disease

284
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Gene-Environment Interactions01:20

Gene-Environment Interactions

973
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Summary
This summary is machine-generated.

Endothelin 1 (EDN1) gene polymorphism rs5370 is linked to a higher risk of preeclampsia (PE). The C allele and CC genotype of rs5370 are associated with increased PE risk, particularly severe and early-onset cases.

Area of Science:

  • Genetics
  • Obstetrics
  • Molecular Biology

Background:

  • Preeclampsia (PE) is a significant pregnancy complication.
  • Endothelin 1 (EDN1) plays a role in vascular tone and blood pressure regulation.
  • Genetic variations in EDN1 may influence PE susceptibility.

Purpose of the Study:

  • To investigate the association between EDN1 gene polymorphisms and the risk of developing preeclampsia.
  • To determine if specific EDN1 single nucleotide polymorphisms (SNPs) are correlated with PE onset and severity.

Main Methods:

  • Genotyping of EDN1 SNPs (rs5370 and rs1800541) in 248 PE patients and 232 healthy controls using Polymerase Chain Reaction (PCR).
  • Statistical analysis including t-tests and Chi-square tests to assess the association between genotypes and PE risk.
  • Evaluation of different genetic models (co-dominant, dominant, over-dominant, recessive) for polymorphism rs5370.

Main Results:

  • The C allele of EDN1 polymorphism rs5370 was significantly associated with an increased risk of PE.
  • rs5370 was strongly linked to severe and early-onset PE, but not mild PE.
  • The CC genotype of rs5370 was linked to higher PE risk, and the TC genotype showed a 1.59-fold increased risk compared to TT/CC.
  • No significant association was found between EDN1 polymorphism rs1800541 and PE risk or severity.

Conclusions:

  • EDN1 gene polymorphism rs5370 is a potential genetic risk factor for preeclampsia.
  • The rs5370 polymorphism, particularly the C allele and CC genotype, is correlated with an elevated risk of developing PE, especially severe and early-onset forms.
