Personalis provides researchers and clinicians accurate DNA sequencing and interpretation of human exomes and genomes. We support researchers engaging in case-control, family-based, or proband-only genomic studies of disease, pharmacogenomics, and cancer. Our ACE (Accuracy and Content Enhanced) Technology supplements a standard exome or genome, substantially increasing its medically-relevant coverage and accuracy. Personalis builds on this enhanced sequencing foundation with innovative algorithms and proprietary databases for alignment, variant calling, annotation, and analysis. Through this comprehensive approach, we provide genomic data and interpretation of the highest accuracy. Our in-house laboratory is CLIA-licensed by the state board of California and CAP-accredited.
