For example, the autosomal dominant condition, achondroplasia is caused by the FGFR3 gene point mutation. The use of nested polymerase chain reaction nested PCR was evaluated to determine sex by detecting a Y chromosome specific signal in the cffDNA from maternal plasma. Blood plasma is separated from the maternal blood sample using a laboratory centrifuge. Cell-free fetal DNA in maternal plasma during physiological single male pregnancies: International Journal of Molecular and Cellular Medicine. Analysis of cffDNA is a method of non-invasive prenatal diagnosis frequently ordered for pregnant women of advanced maternal age. In this study, early determination of fetal gender using cffDNA can be considered as a non-invasive pre-test to determine whether invasive prenatal diagnosis should be performed on a fetus having a risk of X-linked disorders or not. The technique is not currently used for this purpose in Sweden. Analysis of cffDNA is a method of non-invasive prenatal diagnosis frequently ordered for pregnant women of advanced maternal age. In real-time PCR, fluorescent probes are used to monitor the accumulation of amplicons.


  • In previous years, identification of fetal cells in maternal blood circulation has caused a new revolution in non-invasive method of prenatal diagnosis.

    Fetal Sex Determination using Non-Invasive Method of Cell-free Fetal DNA in In previous years, identification of fetal cells in maternal blood circulation has. The non-invasive determination of fetal sex, that include extraction of cell-free fetal DNA in maternal circulation and amplification of X and Y.
    Approximately 11 to Analysis of cffDNA may provide earlier diagnosis of fetal conditions than current techniques.

    Further studies on tumour derived DNAs in the plasma of cancer patients open up the possibility that fetal DNA which originated from apoptotic trophoblasts of the placenta, may also be found in maternal plasma 78. As cffDNA is found in maternal blood, sampling carries no associated risk of spontaneous abortion.

    In this context we employed droplet digital PCR (ddPCR) in order to evaluate the earliest possible fetal sex determination from circulating DNA.

    We hope that non-invasive fetal gender determination using cffDNAs in maternal plasma would allow us to obtain an early knowledge of the fetal sex and adding to timely clinical management. Br J Haematol ; 1: Prenat Diagn ;27 9: The use of cell-free fetal nucleic acids in maternal blood for non-invasive prenatal diagnosis.

    There is a lack of published research into the cost-effectiveness of using NIPD to determine fetal sex or blood group. Early noninvasive prenatal detection of a fetal CRB1 mutation causing Leber congenital amaurosis.
