Testing DeepSomatic’s Ability to Spot Cancer-Related Variants
In the realm of genomic research, the capability to identify cancer-related variants is pivotal. This blog discusses a recent study that evaluated DeepSomatic’s effectiveness across various genomic datasets.
Overview of the Study
In this study, DeepSomatic was trained on three breast cancer genomes and two lung cancer genomes from the CASTLE reference dataset. Its performance was tested using a breast cancer genome not included in the training set, providing a comprehensive assessment of its capabilities.
Performance Against Competitors
DeepSomatic’s models, tailored for three major sequencing platforms, outperformed existing methods. They successfully identified more tumor variants with greater accuracy than tools such as SomaticSniper, MuTect2, and Strelka2. For long-read sequencing, DeepSomatic was compared to ClairS, a deep learning model utilizing synthetic data.
Key Findings
In total, DeepSomatic identified an impressive 329,011 somatic variants across six reference cell lines and an additional preserved sample. It excelled particularly in detecting insertions and deletions (Indels) within genetic sequences.
Indel Detection Success Rates
The performance metrics were revealing. On Illumina sequencing data, DeepSomatic achieved a remarkable 90% accuracy in identifying Indels, compared to 80% from the next-best method. When evaluated on Pacific Biosciences sequencing data, DeepSomatic scored over 80%, while competitors achieved less than 50%.
Conclusion
The study highlights DeepSomatic’s remarkable ability to detect cancer-related variants, particularly Indels, outperforming current alternatives. This advancement affirms the model’s potential to enhance cancer diagnosis and treatment through precise genomic insights.
