Progress in Pathogen Detection by Whole-Genome Sequencing

Whole-genome sequencing and disease-gene detection

Whole-genome sequencing (WGS) offers unique opportunities to identify rare variants that cause disease. We have developed a new software tool, VAAST (Variant Annotation, Analysis and Search Tool) that permits the identification of specific disease-causing mutations in WGS data. VAAST unambiguously identifies two disease-causing mutations in a family quartet in which both offspring have autosoma...

Whole Genome Sequencing: An Efficient Approach in Food Safety Management System

Mapping Challenging Mutations by Whole-Genome Sequencing.

Whole-genome sequencing provides a rapid and powerful method for identifying mutations on a global scale, and has spurred a renewed enthusiasm for classical genetic screens in model organisms. The most commonly characterized category of mutation consists of monogenic, recessive traits, due to their genetic tractability. Therefore, most of the mapping methods for mutation identification by whole...

Identifying insertion mutations by whole-genome sequencing.

Insertion mutagenesis via mobile genetic element is a common technique for the analysis of gene function in model organisms. Next-generation sequencing offers an attractive approach for localizing the site of insertion, but alignment-based mapping of mobile genetic elements is challenging. A computational method for identifying insertion sites is reported herein. The technique was validated by ...

Whole-Genome Bisulfite Sequencing

Next-generation sequencing technology has enabled genome-wide analysis of 5mC nucleotides at single-nucleotide resolution. Previous methods for whole-genome bisulfite sequencing (WGBS) yielded reduced genomic representation due to required DNA shearing, ligation of methylated sequencing adapters, and bisulfite conversion of unmethylated cytidine residues prior to sequencing. One disadvantage of...
