First trimester prenatal diagnosis of congenital rubella: a laboratory investigation.
Acute primary maternal infection with rubella virus during pregnancy often, but not invariably, leads to the congenital rubella syndrome. Diagnosis by detection of virus specific IgM in the mother is not always possible, and in those cases in which IgM is detected the fetus has not necessarily also been infected. A method for direct, prenatal detection of fetal infection would allow more accura...
متن کاملA familial unbalanced subtelomeric translocation resulting in monosomy 6q27-->qter.
Subtelomeric rearrangements have recently gained considerable interest through publications indicating that they may be a major cause for unexplained mental retardation and/or multiple congenital anomalies. 2 As the subtelomeric regions have the highest gene density in the genome, subtelomeric aneusomies are in general thought to have a significant effect on the phenotype. Prenatal onset of gro...
متن کاملFirst trimester prenatal diagnosis of Menkes disease by DNA analysis.
Menkes disease is an X linked recessive disorder of copper metabolism characterised by neurological symptoms and connective tissue manifestations. The defective gene in Menkes disease has recently been isolated and the gene product is predicted to be a copper transporting ATPase. The diagnosis of Menkes disease has hitherto been performed by biochemical analysis, based on intracellular accumula...
متن کاملFirst trimester prenatal diagnosis: earlier is not necessarily better.
In the past few years considerable attention has been given to a relatively new method of prenatal diagnosis known as chorionic villus sampling (CVS). Because CVS can be performed in the first trimester it is hailed by many as a significant advance over amniocentesis. What has not been as publicized, however, are the disadvantages of CVS and earlier prenatal diagnosis. The emotional costs of CV...
متن کاملFirst Trimester Ultrasound in Prenatal Diagnosis—Part of the Turning Pyramid of Prenatal Care
First-trimester sonographic assessment of the risk of chromosomal abnormalities is routinely performed throughout the world, primarily by measuring fetal nuchal translucency thickness between 11-13 weeks' gestation, combined with assessment of serum markers. The development of high-frequency transvaginal transducers has led to improved ultrasound resolution and better visualization of fetal ana...
