A Method for the Detection of Chromosomal Aneuploidies
- Summary
- The non-invasive detection of fetal chromosomal aneuploidies is demonstrated. Alleles of fetal RNA-SNPs present in a biological sample (e.g. maternal blood) containing fetal RNA are detected and quantified in order to determine the ratio of the alleles. This ratio is compared to a standard control consisting of euploid fetuses. Deviation of allele ratio indicates the presence of chromosomal aneuploidy.

Title: Method for the detection of chromosomal aneuploidies
Usefulness: Method for the detection of chromosomal aneuploidies
Summary: The method (M1) is useful for detecting the presence of a chromosomal disorder in the fetus of a pregnant woman (claimed).
Novelty: Detecting chromosomal disorder in fetus of pregnant woman by detecting increase or decrease in ratio of RNA transcribed from genetic locus from chromosome of concern in RNA-containing sample of pregnant woman, compared to standard
