Targeted Resequencing
Introduction to Targeted Resequencing
With targeted resequencing, a subset of genes or regions of the genome are isolated and sequenced. Targeted approaches using next-generation sequencing (NGS) allow researchers to focus time, expenses, and data analysis on specific areas of interest. Such targeted analysis can include the exome (the protein-coding portion of the genome), specific genes of interest (custom content), targets within genes, or mitochondrial DNA.
Benefits of Targeted Resequencing
Targeted resequencing is simpler and more accessible than ever before. Find out how to access the focused power of targeted NGS.
Affordable Sequencing With Focused Content
- Focuses on regions of interest, generating a smaller, more manageable data set
- Reduces sequencing costs and data analysis burdens
- Reduces turnaround time compared to broader approaches
- Enables deep sequencing at high coverage levels for rare variant identification
Compared to broader approaches, such as whole-genome sequencing, targeted sequencing is a more cost-effective method for investigating areas of interest. Targeted resequencing enables researchers to focus on regions that are most likely to be involved in the phenotype under study, conserving resources and generating a smaller, more manageable data set. Targeted approaches can also deliver much higher coverage levels, allowing identification of variants that are rare and more expensive with whole-genome or Sanger sequencing.

Cancer Gene Sequencing
Targeted sequencing studies focus on a select set of genes or gene regions that have known associations with cancer. The deep coverage offered by targeted resequencing allows for higher sensitivity to call variants in rare tumor subclones accurately. Learn more about targeted cancer sequencing.
Rare Disease Targeted Sequencing
Targeted sequencing is a relatively inexpensive technique that interrogates known disease-causing genes. It is most effective for rare disease analysis when a specific condition or disease state is suspected. Learn more about rare disease targeted sequencing.
Complex Disease Research
Mendelian disorders can result from rare genetic variants. Exome sequencing allows targeted exploration of protein-coding regions of the genome to identify the rare variants that contribute to complex genetic diseases. Learn more about complex disease genomics.
Drug Development
In the future, targeted sequencing might be used to validate drug targets and confirm variants of interest for cancer treatment and other therapeutics. Learn more about NGS in drug development.
Mitochondrial Disease Research
Targeted NGS enables researchers to identify and analyze variants associated with mitochondrial disorders. Learn more about mitochondrial sequencing.
