Genetic & Rare Diseases

Empowering early discovery and intervention

We’re dedicated to improving the path to diagnosis for families affected by genetic and rare diseases

Advancing genetic disease testing

Next-generation sequencing technology is helping to drive breakthroughs in genetic disease testing by facilitating identification of disease-causing genetic variants. We recognize the significant impact of genetic and rare diseases on families worldwide, and we’re developing solutions to facilitate early detection and intervention. A genetic diagnosis can help improve outcomes, promote enduring good health, and raise awareness about the importance of genetics in health care.

Genetic disorders and congenital anomalies are primary contributors of hospitalization and mortality in infants.1 At least 39% of rare diseases have an identifiable genetic etiology.2 For adults, 25% of sudden cardiac arrest is due to an inherited genetic condition.3,4

"350 million people worldwide have an undiagnosed disease. I want each and every one of them to find an answer."

Genetic Testing for Rare Diseases

2–6% of the population worldwide is affected by a rare disease.5,6 80% of these rare diseases have a genetic component,7 but many patients struggle for years to receive a diagnosis. We are committed to ending these diagnostic odysseys by better understanding the genomics of rare disease.

Cardiovascular Genomics

Sudden cardiac arrest is one of the leading causes of nontraumatic mortality in the US. Cardiovascular genomics research has identified many genetic variants associated with cardiac conditions.

icon neurogenetics


Genomic research has uncovered genes linked to Alzheimer's disease, multiple sclerosis, Huntington's disease, and Parkinson's disease. Today, neurogenetics and neurogenomics are significant contributors to how we understand the biology of neurodegeneration.

Genetic Disease Testing Stories

WGS for rare genetic disease
Ending the diagnostic odyssey

Whole-genome sequencing for rare genetic disease can lead to a diagnosis in days, potentially helping parents avoid months or years of inconclusive tests. Listen to Dr. Vandana Shashi of Duke University and Kimberly LeBlanc of the Undiagnosed Diseases Network discuss how sequencing can shorten the diagnostic odyssey for patients with rare disease.

Comprehensive next-generation sequencing promotes efficiencies in rare disease analysis

Whole-genome sequencing (WGS) and whole-exome sequencing (WES) offer higher diagnostic utility than chromosomal microarrays. 8 Learn how WGS and WES can create a comprehensive assay, amenable to the latest genomic discoveries, and new findings can be incorporated into existing workflows.
