Abstract excerpt
Fetal nucleic acids in maternal plasma have opened up new possibilities for noninvasive prenatal diagnosis of chromosomal aneuploidies. One approach is based on the measurement of the allelic ratio of single nucleotide polymorphisms in the coding region of placental mRNA. Another approach is through the analysis of DNA fragments with different patterns of DNA methylation between fetal and maternal DNA. One other...
