Whether working with Sanger sequencing, next-generation sequencing (NGS), or long-read sequencing, finding the right software ensures accuracy, efficiency, and meaningful insights.

Sanger Sequencing: The Gold Standard for Accuracy

What Is Sanger Sequencing?

Sanger sequencing is a highly accurate method for detecting small-scale genetic variants, such as single nucleotide polymorphisms (SNPs) and indels, within targeted genomic regions. It is widely used in clinical diagnostics and low-throughput research.

Why Use Sanger Sequencing for Variant Detection?

• High Precision: Sanger sequencing provides unparalleled accuracy for small-scale variants.
• Established Standards: Trusted for clinical applications, including diagnostics and confirmation of NGS results.
• Simplicity: Straightforward workflows make it accessible for labs without extensive bioinformatics infrastructure.

Additional Insights for Experts

• Phred Quality Scores: Sanger sequencing provides highly reliable quality scores for base calls, aiding in the validation of variants.
• Trace File Analysis: Sophisticated software can provide high levels of sensitivity, like Mutation Surveyor software's reference to sample trace comparison algorithms deconvoluting heterozygous indels as well as 2-directional detection of low frequency variants.
• Applications in Rare Diseases: Frequently used in confirming variants identified by NGS in rare disease studies, providing orthogonal validation.

Next-Generation Sequencing (NGS): Powering High-Throughput Analysis

What Is NGS?

Next-generation sequencing (NGS) enables high-throughput detection of genetic variants across the genome. It is ideal for large-scale studies, including cancer genomics, rare disease research, and population genetics.

Why Use NGS for Variant Detection?

• Comprehensive Coverage: Simultaneously detects SNPs, indels, CNVs, and some structural variants across large genomic regions.
• Scalability: Supports projects ranging from targeted panels to whole-genome sequencing.
• Cost-Effectiveness: Efficient for high-throughput applications.

Additional Insights for Experts

• Bioinformatics Pipelines: Integration with tools like GATK or BWA enhances the processing of raw data for highly complex datasets.
• Error Correction: Advances in error-correction algorithms, such as those implemented in NextGENe, help improve variant calling.
• Applications in Oncogenomics: NGS is pivotal for identifying somatic mutations in cancer research, often requiring both detection and deep annotation to determine actionable targets.

Long-Read Sequencing: Resolving Complex Variants

What Is Long-Read Sequencing?

Long-read sequencing technologies, like those from PacBio and Oxford Nanopore, generate extended reads that capture structural variants, enhance the ease and accuracy of haplotyping and improve STR expansion detection often missed by short-read methods.

Why Use Long-Read Sequencing for Variant Detection?

• Structural Variant Detection: Resolves large-scale changes, such as inversions and translocations.
• Improve Haplotyping: Ideal for phasing of alleles.
• Resolving Repetitive Regions: Captures difficult-to-sequence genomic areas.

Additional Insights for Experts

• Phased Variants: Long-read sequencing allows for phasing, enabling researchers to determine which variants occur on the same chromosome.
• Hybrid Approaches: Combining long-read and short-read sequencing improves both cost efficiency and resolution of difficult regions.
• Applications in Genomic Medicine: Critical for identifying structural variants in diseases like muscular dystrophy and other genetic disorders.

How SoftGenetics Excels in Long-Read Analysis

SoftGenetics' tools, including NextGENeLR, support long-read data analysis:

• Structural Variant Detection: Identifies complex rearrangements with high accuracy.
• Haplotyping Workflows: Identifies variants that belong to haplotypes of small genes like HBB as well as Covid-19 and mtDNA.
• Advanced Visualization: Enables clear interpretation of structural changes.
