Rare and Undiagnosed Diseases

Finding a diagnosis for rare diseases is often a race against time. QIAGEN Digital Insights is helping provide answers where none were available before.

Ending the diagnostic odysseys of rare diseases

People living with rare disease often face a diagnostic odyssey, typically waiting years for a diagnosis and receiving multiple misdiagnoses along the way. At QIAGEN Digital Insights, our clinical exome testing solutions are speeding up the rare disease diagnosis timeline. As the owner and operator of the world’s largest, most up-to-date expert-curated knowledge base of biological and clinical findings, QIAGEN Digital Insights ensures genetic testing labs leave no stone unturned in their search for answers.

Whole-exome sequencing for the diagnosis of rare disorders

Whole-exome sequencing (WES) has shown an unprecedented success rate in the identification of disease-causing genetic variants. On average, 25 to 32 percent of patients who undergo clinical exome testing receive a diagnosis [1]. WES testing examines all the protein-coding regions in the genome (exons) simultaneously. Approximately 85% of all disease-causing mutations are located within the exons [2]. By casting a wider net, WES increases the chance of reaching an accurate diagnosis.

Product Disclaimer:

QCI Interpret is an evidence-based decision support software intended as an aid in the interpretation of variants observed in genomic next-generation sequencing data. The software evaluates genomic variants in the context of published biomedical literature, professional association guidelines, publicly available databases, annotations, drug labels, and clinical trials. Based on this evaluation, the software proposes a classification and bibliographic references to aid in the interpretation of observed variants. The software is NOT intended as a primary diagnostic tool by physicians or to be used as a substitute for professional healthcare advice. Each laboratory is responsible for ensuring compliance with applicable international, national, and local clinical laboratory regulations and other specific accreditations requirements.
