Analysis of fetal DNA in maternal plasma has recently been introduced as a new method for noninvasive prenatal diagnosis. In the majority of cases, the Y chromosome-specific sequences are commonly used as a fetus-specific marker with a high risk of false-negative cases. We attempted to develop a sensitive and reliable ...

Prenatal diagnosis (PD) is available to families affected with propionic acidemia (PA), however, it entails a risk of miscarriage. Fetal DNA circulating in maternal blood could allow performing a safe prenatal diagnosis of fetal mutations. Exclusion of the paternal mutation in maternal plasma may avoid conventional PD in cases of ...

Although up to 30% of babies born with haemophilia do not have a family history of the disorder, the remaining 70% are born in families where haemophilia has been diagnosed. It has been estimated that for each male with haemophilia, there are five potential female carriers. Such women will benefit ...

Anomalies of the thorax and abdomen can be found in a number of genetic syndromes. Whilst it may not be possible to make a definitive diagnosis before birth, knowledge of the potential associations can be useful for the prenatal diagnostician when examining the fetus and counselling the parents. In this ...

Ultrasonographic features suggestive of esophageal atresia with or without tracheo-esophageal fistula (EA/TEF) are only in a small minority of fetuses with EA/TEF (<10%) identifiable on prenatal scans.The prenatal diagnosis of EA/TEF relies in principle, on two nonspecific signs: polyhydramnios and absent or small stomach bubble. Polyhydramnios is associated with a ...

Fetal cells and circulating cellfree fetal DNA increases in the maternal circulation in women carrying trisomy 21 fetus. We attempted the use of superoxide dismutase (SOD-1) gene, which is located at the Down Syndrome Critical Region, to overcome this situation for the prenatal screening of Down syndrome. The prospective of ...

The existence of foetal DNA in maternal blood, discovered in 1997, opened new possibilities for noninvasive prenatal diagnosis. This includes foetal sex assessment by the detection of specific Y chromosome sequences in maternal blood, particularly important when a foetus may be affected by an X-linked disorder such as haemophilia. This ...

Prenatal diagnosis of aneuploidy and single-gene disorders is usually performed by collecting fetal samples through amniocentesis or chorionic villus sampling. However, these invasive procedures are associated with some degree of risk to the fetus and/or mother. Therefore, in recent years, considerable effort has been made to develop non-invasive prenatal diagnostic ...
