Genetic Screens02:46

Genetic Screens

5.8K
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...

Pharmacogenomics: Identification of New Drug Targets

29
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...

Human Genetics

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...

Pharmacogenetics and Pharmacogenomics: Overview

46
Pharmacogenetics and pharmacogenomics examine how genetic factors influence an individual's response to drugs. While pharmacogenetics focuses on the impact of specific genetic variants on drug effects, pharmacogenomics takes a broader approach, studying how genetic variation across populations contributes to differences in drug responses. These fields aim to explain why individuals may experience varying levels of efficacy or adverse reactions to the same medication.Variability in drug...

Behavioral Genetics and Its Designs

1.2K
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...

Summary
This summary is machine-generated.

Genetic Health Practitioners (GHPs) find direct-to-consumer genetic testing (DTC-GT) counseling necessary but outside their scope, desiring clearer guidelines and industry oversight. More research is needed on DTC-GT counseling efficacy.

Area of Science:

  • Genetics
  • Healthcare Policy
  • Consumer Health

Background:

  • Direct-to-consumer genetic testing (DTC-GT) has seen significant growth.
  • Understanding Genetic Health Practitioners' (GHPs) perspectives on DTC-GT is limited.

Purpose of the Study:

  • To consolidate research on GHP experiences and attitudes towards DTC-GT.
  • To identify GHP and consumer needs and knowledge gaps in DTC-GT counseling.

Main Methods:

  • A scoping review of 44 publications (2007-2025) was conducted.
  • Literature covered GHP attitudes, counseling experiences, company-provided counseling, and counselor-designed tools.

Main Results:

  • Most studies (82%) focused on GHPs in clinical settings.
  • GHPs view counseling as essential for DTC-GT but outside their current responsibilities.
  • GHPs desire clearer guidelines, resources, and industry regulation, expressing concerns about conflicts of interest.

Conclusions:

  • Clarify GHP roles and scope in clinical DTC-GT practice.
  • Develop best-practice models for DTC-GT counseling.
  • Conduct further research on the nature and efficacy of GHP counseling in various settings.
