Trisomy 13 is typically due to having three full copies of chromosome 13 in each cell in the body, instead of the usual two copies. Trisomy 18 and trisomy 13 are genetic disorders that include a combination of birth defects. Fetal ultrasound during pregnancy can also give information about the possibility of trisomy 18 or 13.
