Summary of "Development of a new methylation-based fetal fraction estimation assay using multiplex ddPCR."

Non-invasive prenatal testing (NIPT) for fetal aneuploidies has rapidly been incorporated into clinical practice. Current NGS-based methods can reliably detect fetal aneuploidies non-invasively with fetal fraction of at least 4%. Inaccurate fetal fraction assessment can compromise the accuracy of the test as affected samples with low fetal fraction have an increased risk for misdiagnosis. Using a novel set of fetal-specific differentially methylated regions (DMRs) and methylation sensitive restriction digestion (MSRD), we developed a multiplex ddPCR assay for accurate detection of fetal fraction in maternal plasma.

Medical and Biotech [MESH] Definitions

A complication of pregnancy in which the UMBILICAL CORD wraps around the fetal neck once or multiple times. In some cases, cord entanglement around fetal neck may not affect pregnancy outcome significantly. In others, the nuchal cord may lead to restricted fetal blood flow, oxygen transport, fetal development, fetal movement, and complicated delivery at birth.

Specialized proteins that are preferentially expressed during FETAL DEVELOPMENT.

The development of the PLACENTA, a highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products between mother and FETUS. The process begins at FERTILIZATION, through the development of CYTOTROPHOBLASTS and SYNCYTIOTROPHOBLASTS, the formation of CHORIONIC VILLI, to the progressive increase in BLOOD VESSELS to support the growing fetus.

Proteins that are preferentially expressed or upregulated during FETAL DEVELOPMENT.

Morphological and physiological development of FETUSES.
