The hardest part is not knowing

When symptoms don't add up and every test leads to more questions, it's easy to feel stuck.

Genetic testing from GeneDx helps you move forward

Because 80% of rare diseases are genetic in nature¹, understanding your DNA can help identify the cause of a condition, guide treatment options, and connect you to the right care and support².

Why test?

GeneDx is the #1 provider of pediatric and rare disease genetic testing³, trusted by clinicians and families to deliver clarity when it matters most. We help:

Find answers when traditional tests don’t explain the symptoms.
Empower your healthcare decisions with more precise information.
Support your family’s future by uncovering important inherited insights.
Move forward with confidence knowing what’s behind your condition.

Exome testing can often find answers that other tests miss

Multi-gene panels and chromosomal microarrays don’t capture the full picture.

Panels miss nearly one-quarter of diagnoses that exome testing finds¹.
Exome testing is over twice as likely to lead to a diagnosis compared to chromosomal microarray².

Meet Layla

Layla was born with a bowel obstruction that required two emergency surgeries in her first weeks of life. Considered as a typical short-bowel patient, Layla didn’t respond to treatment as expected. Fortunately, her care team used GeneDx rapid genome sequencing to uncover TTC7A deficiency, a rare condition that affects both the intestines and the immune system. Learn how her treatment drastically changed—helping Layla not just survive, but thrive.
