Mutation Mapping and Identification by Whole-Genome Sequencing.

Geneticists approach biology with a simple question: which genes are required for the pathway or process of interest? Classical genetic screens (aka forward genetics) in model organisms such as Caenorhabditis elegans have been the method of choice for answering that question. Next-generation sequencing provides the means to generate a comprehensive list of sequence variants, including the mutation of interest. Herein is described a workflow for sample preparation and data analysis to allow the simultaneous mapping and identification of candidate mutations by whole-genome sequencing in Caenorhabditis elegans.
