Which trisomy is not compatible with life?

Trisomy 18 and a similar diagnosis, trisomy 13, are among a few congenital syndromes traditionally described in the medical literature as “incompatible with life.” Trisomy 18 occurs in 1 in 5,000 live births, and trisomy 13 in 1 in 16,000; survival statistics for both diagnoses are equally poor.

How old is the oldest person with trisomy 13?

Full trisomy 17 has never been reported in a living individual in the medical literature.

Can ultrasound detect trisomy 18?

Trisomy 18, also known as Edwards’ syndrome, is a genetic disorder that affects babies and can often be diagnosed before birth. A fetal ultrasound during pregnancy can show features that are suggestive of trisomy 18, and the detection rate is about 90% during pregnancy weeks 14-21.
