Early and highly accurate 22q11.2 deletion screening is possible with SNP-based NIPT
Panorama AI was validated in SMART, the largest prospective NIPT study, combining artificial intelligence (AI) with Natera’s proprietary SNP-based methodology to improve both accuracy and the positive predictive value (PPV) for 22q11.2 deletions.1-3

22q11.2 deletion syndrome prevalence compared to commonly screened conditions
22q11.2 deletion syndrome is more common than cystic fibrosis and spinal muscular atrophy. It can affect any pregnancy and detection with ultrasound is limited.2 Panorama offers non-invasive, accurate screening for early detection.
Importance of early screening
Watch this brief video from Dr. Samantha Leonard at the 2021 ISPD conference discussing prenatal interventions to help improve outcomes such as:
- Delivery at tertiary center
- Calcium-level monitoring at birth
- Delayed live-vaccine administration
- Palatal evaluation for potential feeding and breathing issues
Children who are not diagnosed prenatally can have an extensive diagnostic odyssey. The average age of diagnosis is almost five years old.
