About Us

Genomics and Pathology Services (GPS), a collaborative initiative between the Department of Pathology & Immunology and the Department of Genetics, is a clinical genomics laboratory at Washington University School of Medicine in St. Louis.

Located in the state-of-the-art Cortex building, our CAP-accredited, CLIA-certified laboratories deliver clinically validated testing supported by extensive clinical and genomic experience and advanced technologies.

GPS’ clinical genomic tests improve patient care by enabling a personalized approach to medicine. Our next-generation sequencing tests return actionable genomic intelligence across multiple key disease-relevant genes.

Sequencing results are interpreted by board-certified pathologists and clinical geneticists. Variants are categorized by medical significance in a concise clinical report. These results help ordering physicians stratify disease subtypes and identify optimal patient treatment strategies.

GPS also provides customized assay development in support of clinical trials and research.

In addition to next-generation sequencing, our capabilities include Sanger sequencing, microarray for CNV analysis and SNP genotyping, quantitative digital PCR, a wide range of cytogenetic tests and clinical bioinformatics.

Collaborators benefit from the expertise of GPS genomicists and bioinformaticians during the entire design and validation process.
