Statistical considerations for digital approaches to non-invasive fetal genotyping
MOTIVATION A growing body of literature has demonstrated the potential for non-invasive diagnosis of a variety of human genetic diseases using cell-free DNA extracted from maternal plasma samples in early gestation. Such methods are of great significance to the obstetrics community because of their potential use as clinical standard of care. Proof of concept for such approaches has been establi...
متن کاملA multiplex PCR for non-invasive fetal RHD genotyping using cell-free fetal DNA.
AIM To design a protocol for non-invasive prenatal diagnosis of fetal Rhesus D (RhD) status. MATERIALS AND METHODS A total of 112 single lymphocytes were used to test the efficiency of the assay. The protocol was validated using blood samples from 84 RhD-negative pregnant women at 7-24 weeks of gestation. Cell-free DNA (cfDNA) was enzymatically digested using AciI and analyzed by a polymerase...
متن کاملP-226: Non-Invasive Prenatal Screening for Fetal Chromosomal Anomalies in South of Iran
Background: Prenatal diagnosis for Fetal Chromosomal anomalies currently relies on assessment of risk followed by a combination of biochemical and nuchal translucency. Trisomy 21 is the most common trisomy that is associated with intellectual disability. Pregnant women who receive a prenatal diagnosis of trisomy 21 currently have the option of continuing or terminating their pregnancy, but no f...
متن کاملNon-invasive fetal ECG analysis.
Despite the important advances achieved in the field of adult electrocardiography signal processing, the analysis of the non-invasive fetal electrocardiogram (NI-FECG) remains a challenge. Currently no gold standard database exists which provides labelled FECG QRS complexes (and other morphological parameters), and publications rely either on proprietary databases or a very limited set of data ...
