The Detection of Genetic
The Detection of Genetic
Friday, March 29, 2013
Amniocentesis and CVS, in the not too distant future, by a simple and for the same purpose, accurate and less invasive: sufficient for the detection of genetic abnormalities in the offspring is, a blood sample from the mother are analyzed. The discovery by researchers at Stanford University (USA), the first sequenced the genome of a fetus with only a sample of the mothers.
The results of the new approach, was published in Nature, had carried out the movements of the other study by researchers at the University of Washington (USA), in order to achieve the same result, but a blood sample dual use of the mother and the father of the future . The technique of DNA sequencing was performed at Stanford, but requires no paternal blood: an advantage of no small importance in cases where the father is unknown or unwilling to acknowledge paternity.
Syndrome of pregnancy for a fatherAs the cost of technology continues to decline, the researchers believe that it will be easier to diagnose genetic diseases in the first trimester of pregnancy. "We are interested in determining the conditions that can be treated before or shortly after birth - says Stephen Quake, the first author of the study -. Without this diagnosis, children with metabolic disorders or immune system treated, cured to be symptoms. "
Procedures that return result sets can say the researchers from Stanford, an abortion every 200 pregnancies - amniocentesis and chorionic villus sampling (CVS) to determine whether the fetus carries genetic abnormalities can be done by inserting a needle into the uterus. New research would instead identified with lower invasiveness, a large number of genetic diseases. "This important study - closed Quake - instead confirms our ability to test individual genetic disorders of the fetus only the mothers blood to identify."
