Clinical Whole Exome Sequencing (CLIA/CAP)

Genetic testing, known as DNA testing, allows geneticists to determine bloodlines and diagnose genetic diseases. With the advent of next-generation sequencing (NGS) technologies, whole exome sequencing (WES) is widely used as a cost-effective and accurate method of genetic testing.

What is Clinical WES?

Whole exome sequencing (WES) employs high-throughput sequencing of more than 20,000 genes per individual, enriched through sequence capture technology. WES targets all protein-coding regions (~1% of the whole genome) responsible for 85% of known disease-causing variants. It allows for molecular diagnosis of genetic diseases and enables the exploration of novel mutations and new pathogenic mechanisms. Compared to whole genome sequencing, WES has the advantage of a greater sequencing depth and delivers more effective data.

For patients with symptoms of genetic disorders, clinical exome sequencing plays an important role in quickly identifying potential variants. Clinical exome sequencing offers a one-step solution for challenging issues, such as diagnosing patients with genetic heterogeneity or atypical presentation, where it is unclear which genes are causing the specific genetic condition. The accuracy of clinical-grade sequencing at Novogene is ensured by standardizing each testing step as well as strictly controlling for quality throughout the entire process. Clinical whole exome sequencing at Novogene is validated and performed in our CLIA/CAP laboratories to achieve the high standards of clinical-grade sequencing, thereby providing precise diagnosis.

Genomic Profiling

NovoPMTM 2.0 – A comprehensive somatic tumor profiling panel that analyzes 484 genes for clinically important alterations at the DNA level. These genes are relevant for the diagnosis and/or treatment of various solid tumors according to NCCN guidelines and the medical literature.

FFPE RNA-seq

This assay applies the power of next-generation sequencing (NGS) to gene expression profiling of typical clinical samples. Based on the TruSeq RNA Exome Library Prep Kit and Novogene’s in-house bioinformatics pipelines, it provides robust and comprehensive transcriptomic analysis of human RNA isolated from FFPE and other low-quality clinical samples.
