Genetic Screens

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 result in visible changes...

Area of Science:

  • * Genetics and genomics
  • * Developmental biology
  • * Comparative genomics

Background:

  • * Vertebrate model organisms like zebrafish are crucial for studying gene function.
  • * Identifying genetic variants, such as mutations, in these models remains a significant challenge.
  • * Efficient methods are needed to pinpoint causative genes for observed phenotypes.

Purpose of the Study:

  • * To develop and apply an efficient method for identifying genetic mutations in zebrafish.
  • * To isolate the specific gene affected in the mozartkugelp11cv (mzlp11cv) mutant zebrafish line.

Main Methods:

  • * Employed a combination of microarray capturing and next-generation sequencing (NGS).
  • * Targeted genomic regions for sequencing to identify variations.
  • * Applied the technique to the mzlp11cv mutant zebrafish to find the causative mutation.

Main Results:

  • * Successfully identified a 31-base pair (bp) deletion in the macf1 gene.
  • * The identified deletion in macf1 is the likely cause of the mzlp11cv mutant phenotype.
  • * Demonstrated the efficacy of the combined microarray capturing and NGS approach.

Conclusions:

  • * The developed technique significantly enhances the efficiency of mutation discovery in vertebrate genomes.
  • * This method provides a powerful tool for genetic research using zebrafish and potentially other model organisms.
  • * Facilitates faster identification of genes underlying specific mutations and phenotypes.
