Panorama uses a simple blood draw from the mother to examine cell-free DNA found in maternal blood originating from both mother and fetus to screen for chromosome abnormalities, including trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), trisomy 13 (Patau syndrome), monosomy X (Turner syndrome), and triploidy
6) CNVs and delineation of breakpoints are more accurately determined with SNP arrays, and they are adept at identifying triploidy
mosaicism, which are relatively frequently found in prenatal samples.
In addition, protective measures that may assist in insulating wild clams from their farmed counterparts may include maturation control through triploidy
(Vadopalas & Davis 2004).

It also avoids some of the technical problems associated with guanine cytosine (GC) bias (discussed below) and can detect fetal triploidy

Holoprosencephaly has also been associated with triploidy
, trisomy 13, trisomy 18, and a number of other syndromes.
Consistent with what is known about the technique of microarray testing; however, none of the triploidy
pregnancies were identified, but 15 of 17 were correctly called using maternal cell contamination results, he noted.
