Abstract excerpt

OBJECTIVE: The purpose of this research was to attempt a preliminary study of noninvasive prenatal diagnosis of Down syndrome in Southwest Chinese gravidas by using the plasma placental RNA allelic ratio. METHODS: The genotypes of the single-nucleotide polymorphisms (SNPs) located in the transcribed regions of the gene PLAC4 were detected in population samples collected in Southwest China by using polymerase...
