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...

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...

Genome-wide Association Studies-GWAS

14.8K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Area of Science:

  • Neurogenetics
  • Computational Biology
  • Genomics

Background:

  • Neurodevelopmental and neurodegenerative disorders (NNDs) involve central nervous system dysfunction and complex comorbidities.
  • High-throughput sequencing identifies genetic risk loci, but establishing causality and molecular mechanisms requires advanced neurogenetic approaches.

Purpose of the Study:

  • To present a method for prioritizing genetic risk loci in NND pathogenesis by assessing their impact on gene regulation.
  • To highlight the utility of a tissue-specificity gene expression index and artificial intelligence (AI) for interpreting genetic risk elements in NNDs.

Main Methods:

  • Estimating the impact of genetic risk loci on gene regulation.
  • Applying a tissue-specificity gene expression index to identify brain-specific expressed genes.
  • Utilizing artificial intelligence (AI) to integrate biological impacts and identify causative relationships.

Main Results:

  • Genetic risk loci for NNDs show disproportionate enrichment in brain-specific expressed genes, suggesting direct roles in brain dysfunction.
  • The tissue-specificity index aids in identifying non-brain contexts contributing to NND pathogenesis.
  • AI integration of risk loci impacts facilitates the identification of causative genetic factor combinations.

Conclusions:

  • The developed approach enhances the prioritization of genetic risk loci for NNDs by focusing on gene regulation and brain specificity.
  • AI and tissue-specificity indices are crucial tools for unraveling the complex genetic underpinnings of NNDs and identifying novel therapeutic targets.
