Human Genetics01:28

Human Genetics

2.0K
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...

Pharmacogenomics: Identification of New Drug Targets

108
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Genetic Screens02:46

Genetic Screens

5.9K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Epistasis Analysis01:09

Epistasis Analysis

6.3K
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...

Behavioral Genetics and Its Designs01:23

Behavioral Genetics and Its Designs

1.4K
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

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

142
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...

Area of Science:

  • Psychiatry
  • Behavioral Genetics
  • Neuroscience

Background:

  • Identifying specific genetic contributions to psychopathology has been more difficult than expected.
  • Previous research has faced challenges in pinpointing direct genetic links to mental disorders.

Purpose of the Study:

  • To showcase innovative methods for identifying genetic contributions to psychopathology.
  • To report findings from a series of studies on the genetic basis of mental disorders.
  • To emphasize the role of endophenotypes in understanding psychopathology.

Main Methods:

  • Utilized a remarkable set of studies employing novel methodologies.
  • Focused on identifying endophenotypes as intermediate phenotypes.
  • Integrated findings within the framework of the NIMH Research Domain Criteria (RDoC).

Main Results:

  • The immediate yield of positive genetic findings was somewhat limited.
  • The results, though limited, provide valuable insights into genetic pathways.
  • Demonstrated the utility of endophenotypes in genetic research for psychopathology.

Conclusions:

  • The studies inspire further innovation in identifying causal pathways to psychopathology.
  • There will be an increased emphasis on endophenotypes in future research.
  • The endophenotype perspective is highly compatible with the NIMH RDoC initiative.
