Genetic Screens

5.2K
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...

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.

Gene Conversion

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Genetic Variation01:25

Genetic Variation

889
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Summary

Large-scale RNA sequencing can reveal individual genetic information. A list of allele-specific genes, even without explicit variant data, can link individuals to their genotypes and phenotypes, posing privacy risks.

Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • RNA sequencing (RNA-Seq) is increasingly used in large population studies.
  • Surveying allele-specific gene expression (ASGE) is a growing area of research.
  • ASGE analysis can reveal insights into gene regulation and function.

Purpose of the Study:

  • To investigate whether allele-specific gene lists can infer individual genetic information.
  • To assess the privacy implications of ASGE data.
  • To explore the potential for re-identifying individuals from ASGE profiles.

Main Methods:

  • Utilized existing datasets of allele-specific gene expression.
  • Developed computational methods to infer genetic variants from ASGE data.
  • Tested the ability to link inferred variants back to individual genotypes and phenotypes.

Main Results:

  • A list of allele-specific genes was sufficient to recover key genetic variants.
  • Individuals could be linked back to their original genotypes and phenotypes using ASGE data alone.
  • This demonstrates a potential privacy risk associated with large-scale RNA sequencing.

Conclusions:

  • Allele-specific gene expression patterns contain significant genetic information.
  • RNA sequencing data, even without explicit variant calls, can pose privacy risks.
  • Further research is needed to develop privacy-preserving methods for genomic data analysis.
