Genetic Screens

5.6K
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

384
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Bioavailability Study Design: Healthy Subjects Versus Patients

143
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Analysis of Population Pharmacokinetic Data01:12

Analysis of Population Pharmacokinetic Data

673
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

Drug Dosing: Obese Patients

218
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Area of Science:

  • Genetics and Precision Medicine
  • Bone Health and Osteoporosis Research
  • Preventive Healthcare Strategies

Background:

  • Genetic factors significantly impact osteoporosis development and fracture risk.
  • Current osteoporosis screening guidelines do not incorporate genetic risk assessment.
  • There is a need for personalized screening protocols based on individual genetic predispositions.

Purpose of the Study:

  • To determine personalized osteoporosis screening ages using polygenic risk scores (PRS).
  • To evaluate the potential of PRS in enabling early detection of osteoporosis.
  • To advance precision prevention strategies for osteoporosis.

Main Methods:

  • Prospective cohort study of 223,818 women from the UK Biobank.
  • Participants categorized into low, medium, and high PRS subgroups.
  • Calculated 10-year cumulative osteoporosis risk, risk-adapted screening ages, and risk advancement periods (RAP).

Main Results:

  • At age 65, the general female population has a 5.95% 10-year osteoporosis risk.
  • High-PRS women reached this threshold at age 60; low-PRS women at age 69.
  • High-PRS individuals developed osteoporosis significantly earlier than medium-PRS (4.99 years earlier).

Conclusions:

  • Integrating PRS into osteoporosis screening can revolutionize prevention.
  • Early detection in genetically high-risk women is possible, preceding current guidelines.
  • This precision prevention approach may substantially decrease the population burden of osteoporotic fractures.
