early non-invasive determination of fetal sex using cell-free dna
the first step in the prenatal diagnosis of x-linked genetic disorders is determining fetus gender. current invasive methods to obtain the dna source of the fetus instead of its miscarriage risk, has harmful stress for high risk pregnancies. cell free fetal dna (cffdna) circulating in the maternal blood, has now become a useful source of noninvasive prenatal diagnosis. considering limitation of...
متن کاملfetal sex determination using non-invasive method of cell-free fetal dna in maternal plasma of pregnant women during 6th– 10th weeks of gestation
in previous years, identification of fetal cells in maternal blood circulation has caused a new revolution in non-invasive method of prenatal diagnosis. low number of fetal cells in maternal blood and long-term survival after pregnancy limited the use of fetal cells in diagnostic and clinical applications. with the discovery of cell-free fetal dna (cffdna) in plasma of pregnant women, access to...
متن کاملSex determination using free fetal DNA in early pregnancy: With the approach to sex linked recessive disorders
SRY Abstract Introduction: Prenatal diagnosis is testing for detection of diseases or conditions in a fetus or embryo before it is born. Most of prenatal diagnostic (PD) techniques are invasive and done in late stages of pregnancy. Using fetal DNA in maternal blood for fetal sex determination in early pregnancy might help in management of X-linked genetic diseases. This study aimed to investiga...
متن کاملEvaluation of Sample Stability and Automated DNA Extraction for Fetal Sex Determination Using Cell-Free Fetal DNA in Maternal Plasma
OBJECTIVE The detection of paternally inherited sequences in maternal plasma, such as the SRY gene for fetal sexing or RHD for fetal blood group genotyping, is becoming part of daily routine in diagnostic laboratories. Due to the low percentage of fetal DNA, it is crucial to ensure sample stability and the efficiency of DNA extraction. We evaluated blood stability at 4°C for at least 24 hours a...
متن کاملPrenatal determination of farm animal fetal sex using free fetal DNA in maternal plasma
In many farm animal species, the preference of a specific sex is obvious mainly due to commercial implications; so for comprehensive and efficient results in the livestock management plans specially breedingand selection programs, it is necessary to include acost-effective and reliable strategy for early determination of fetal sex. Several invasive and non-invasive approaches have been establis...
