Prenatal detection of aneuploidy and imbalanced chromosomal arrangementsby massively parallel sequencing.
Fetal chromosomal abnormalities are the most common reasons for invasive prenatal testing.
Noninvasive Fetal Trisomy (NIFTY) test: an advanced noninvasive prenatal diagnosis methodology for fetal autosomal and sex chromosomal aneuploidies
Conventional prenatal screening tests, such as maternal serum tests and ultrasound scan, have limited resolution and accuracy.
Non-invasive prenatal screening of fetal Down syndrome by maternal plasma DNA sequencing intwin pregnancies.
Non-invasive prenatal screening for fetal Down syndrome (NIFTY) by maternal plasma sequencing was performed in 12 subjects with twin pregnancies, including 11 with normal fetuses and 1 with discordant fetal Trisomy 21.

To report the feasibility of fetal chromosomal deletion/duplication detection using a novel bioinformatic method of low coverage whole genome sequencing of maternal plasma.
Noninvasive prenatal testing of trisomies 21 and18 by massively parallel sequencing of maternalplasma DNA in twin pregnancies.
The objective of this study is to assess the performance of noninvasive prenatal testing for trisomies 21 and 18 on the basis of massively parallel sequencing of cell-free DNA from maternal plasma in twin pregnancies.
Genetic effects of a 13q31.1 microdeletiondetected by noninvasive prenatal testing (NIPT).
Microdeletions of chromosome 13q31.1 are relatively rare. These types of deletions may cause different genetic effects on genotypes and/or phenotypes.
