Genetic Screens

5.3K
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...

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Area of Science:

  • Biotechnology
  • Bioinformatics
  • Genomic Security

Background:

  • Biotechnology offers significant promise but carries risks of misuse.
  • Identifying the source of genetic engineering, or 'genetic engineering attribution', is crucial for deterring misuse but remains a challenge.

Purpose of the Study:

  • To develop and validate a method for accurate genetic engineering attribution.
  • To assess the feasibility of using machine learning for identifying genetic designers.
  • To create a framework for integrating attribution predictions into broader investigations.

Main Methods:

  • Recurrent neural networks were trained on DNA motifs and phenotype data.
  • Model performance was evaluated for attribution accuracy across over 1,300 distinct laboratories.
  • A calibration framework was developed to weigh model predictions against other evidence.

Main Results:

  • The developed models achieved 70% accuracy in distinguishing between over 1,300 genetic design laboratories.
  • The calibration framework improved model usability, achieving within 1.6% of perfect calibration.
  • Simple models accurately predicted the nation-state-of-origin and ancestor laboratories.

Conclusions:

  • Machine learning models trained on genetic data can effectively attribute genetic engineering activities.
  • An integrated attribution toolkit, including origin and ancestor lab prediction, can enhance responsible innovation and international security.
