The SNP technology also can screen for triploidy and has unparalleled accuracy with fetal sex determination.
Another direct method of triploidy verification is the use of polymorphic DNA markers, such as microsatellites (Slabbert et al.
We found that the 15 STR loci in the Identifiler assay were sufficient for distinguishing multiple trisomies from triploidy.
Of those pregnancies, there were a total of 37 aneuploid fetuses--1 with trisomy 13, 8 with trisomy 18, 22 with trisomy 21, 4 with 45X, 1 with 47XXY, and 1 with triploidy.
Triploidy occurs in roughly 1 out of 2,000 pregnancies at 12 weeks gestation, and it is known to cause severe fetal abnormalities, elevated risks for spontaneous abortion, pre-eclampsia, hemorrhaging, molar placentas, and choriocarcinoma, a form of cancer that occurs in the uterus.

In addition to determining copy number, the method can also reconstruct haplotypes and potentially identify abnormalities that escape detection using counting methods, such as triploidy and uniparental disomy.
29) Four cases described exhibited chromosomal abnormalities including trisomy 13, Klinefelter syndrome (47,XXY), triploidy (69,XXX), and 46,XXp-.

To test the effects of storage and karyotype, AF samples obtained from women carrying euploid fetuses (n = 19) and from aneuploid fetuses with trisomies 21 (n = 16), 18 (n = 9), or 13 (n = 3); triploidy (n = 4); and monosomy X (n = 2) (see Table 1) were frozen at -80 [degrees]C.
Structural rearrangements, monosomy X, triploidy, and tetraploidy also were found.
