Mutation discovery by targeted genomic enrichment of multiplexed barcoded samples

Area of Science:

• Genomics
• Molecular Biology
• Genetics

Background:

• Next-generation sequencing (NGS) and targeted genomic enrichment accelerate mutation discovery.
• Existing protocols can be limited in flexibility and efficiency for large-scale screening.

Purpose of the Study:

• To develop and validate a streamlined protocol for genomic enrichment of pooled, barcoded samples.
• To improve experimental flexibility and efficiency in mutation discovery using NGS.

Main Methods:

• A novel protocol for targeted genomic enrichment of pooled barcoded samples was developed.
• The method was applied to screen 770 genes (1.4 Mb) in 30 N-ethyl-N-nitrosourea (ENU)-mutagenized rat samples.

Main Results:

• The protocol demonstrated high sensitivity, identifying known variants at >96% accuracy.
• New mutations were detected with a low false positive rate of less than 1 in 8 megabases.

Conclusions:

• The described protocol significantly enhances the efficiency and flexibility of targeted genomic enrichment for mutation discovery.
• This approach is effective for large-scale genetic screening in mutagenized populations.
