Sanger Minor Variant Finder Software

5% somatic variant detection using Sanger sequencing

Applied Biosystems™ Minor Variant Finder Software is new software developed for the detection and reporting of minor mutations by Sanger sequencing. Minor variants are single nucleotide polymorphisms (SNPs) that present as a minor component with a contribution of less than 25% at a given allele.

The ability to detect low-level somatic mutations is critical in research areas such as oncology, infectious disease, and inherited disease. The improved sensitivity achieved through Minor Variant Finder Software makes Sanger sequencing the ideal choice for oncologists and/or pathologists to call low-frequency somatic variants (5% or below) where the number of relevant targets is often limited. Depending on the cancer type, the moderate number of relevant variants in oncogenes (for example, KRAS, NRAS, etc.) and/or tumor suppressor genes (for example, TP53) could be detected by the gold-standard Sanger sequencing with Minor Variant Finder, quickly and cost-effectively. It is also an important confirmatory method for next-generation sequencing (NGS) results.

Call minor variants at a detection level as low as 5%

The innovative algorithm of the Minor Variant Finder Software neutralizes the background noise using a control sample, and enables calling of minor variants at a detection level as low as 5%.  Through the noise minimization process of the software, the imported Sanger sequencing data results in a clean electropherogram for visual confirmation of these minor variants.  Review indicators are also set up to help call any potential minor variants revealed after the analysis. Minor variants can be detected on both forward and reverse strands to confirm findings.

Sequence a moderate number of targets at the lowest cost
plate

Sanger sequencing is a cost-effective option when running a limited number of targets. The improved sensitivity achieved through Minor Variant Finder Software makes Sanger sequencing the ideal choice for oncology and pathology research labs to call somatic variants, where the numbers of relevant targets are often limited. It also provides an easy and flexible way to augment fixed gene panels.

Critical results faster
clock-220x117

Take advantage of the fast turnaround time of Sanger sequencing. Sample to result can be achieved within the same day, providing you with critical results faster.  

Confirm NGS findings in alignment view and Venn diagram
NGS and Sanger variants

For high-throughput labs using NGS technology, minor variants from NGS findings can be confirmed with Sanger sequencing quickly and cost-effectively. The confirmation data can be visualized in an alignment view and Venn diagram for reporting.

Description

BasecallerThe software can analyze .ab1 files that have been basecalled with KB Basecaller v1.4 or later and that contain sequences that have not been edited with a resequencing software application such as Applied Biosystems SeqStudio SeqScape Software.
Compatible genetic analyzersData from Applied Biosystems SeqStudio, 3500, 3130, and 3730 genetic analyzers has been tested with the Minor Variant Finder Software. Data from the 3100 models is supported if it is basecalled with the basecaller version stated above.
