Susan Bowen for redOrbit.com - Your Universe Online Scientists at the University of Massachusetts Medical School have made a huge breakthrough in our understanding of Down's syndrome. They reported in the online science journal Nature, that in a lab, they have switched off the extra chromosome that causes the disorder in humans. This is the proof-of-principal that opens the doorway for exciting new discoveries about this condition. Down's syndrome is the world's leading genetically...

Physicians are well aware that the chance of birthing a child with Down's syndrome increases with the age of the mother, especially for those over 35. Researchers are now also finding links between Down's syndrome and drugs used in in-vitro fertilization (IVF) for older women, BBC News reports. UK researchers looking at 34 couples have discovered a link with IVF in older women disturbing the genetic material of her eggs. The magnitude of the risk is still unknown but it could also cause many...

(Ivanhoe Newswire) -- A test that uses the latest DNA technology to analyze genetic components in a pregnant woman's blood could predict Down's syndrome in unborn babies, according to new research. Down's syndrome occurs when an individual has three, rather than two, copies of the 21st chromosome. This additional genetic material alters the course of development. Older women are at a higher risk of giving birth to a baby with Down's. Women in high-risk groups typically undergo a combination...

Researchers say that a blood test during pregnancy could one day replace more invasive tests for Down's syndrome. Women that are at high-risk are currently offered an amniocentesis test, which carries a risk of miscarriage. However, Dutch researchers told a fertility conference that they are on the verge of developing an accurate way of testing the mother's blood for chromosome disorders in the fetus. Experts said it was promising but too early to determine its effectiveness. The test is...

Research undertaken in recent years on Down's syndrome has focused on the DYRK1A gene. The superexpression of this gene affects transmission in the neurones, according to Mr Garikoitz Azkona. In his PhD thesis, The molecular bases of neuropathology in Down's syndrome: the role of DYRK1A, Mr Azkona argues that this failure in neurone transmission could be behind the problem that persons with Down's syndrome have regarding visual-spatial memory. Persons with Down's syndrome usually have great...

A study by neuroscientist William C. Mobley, MD, PhD, chair of the Department of Neurosciences at the University of California, San Diego School of Medicine, and colleagues at Stanford University Medical School has demonstrated a possible new approach to slowing the inevitable progression of cognitive decline found in Down\'s syndrome. The study, published in Science Translational Medicine on November 18, revealed two important new findings about Down\'s syndrome in a mouse model: 1) there is...

A newly identified molecular pathway that directs stem cells to produce glial cells yields insights into the neurobiology of Down's syndrome and a number of central nervous system disorders characterized by too many glial cells, according to a recent study by researchers at the Salk Institute for Biological Studies.Their findings, to be published in the March 13 online edition of Cell Death and Differentiation, indicate that synaptojanin-1, a central component of the pathway, is essential to...

A new national screening strategy in Denmark has halved the number of infants born with Down's syndrome and increased the number of infants diagnosed before birth by 30%, according to a study published on bmj.com today. Many countries, including England, Australia and New Zealand, are trying to introduce national screening strategies for Down's syndrome, but are facing a variety of problems because of a lack of consensus about the screening policy and logistical challenges. In 2004, the...

Scientists say a prenatal blood test can determine if an unborn baby has Down's syndrome, without the risk to the fetus from past invasive testing methods, according to U.S. researchers. Stephen Quake led a team of researchers at Stanford University in California to create a way to look for the extra chromosomes that cause Down's and similar birth detects. Babies with Down's syndrome have an extra copy of chromosome 21, causing physical and intellectual impairments. The test also detects...

Antenatal screening services for conditions such as Down's syndrome do not always give parents the time needed to make decisions about their unborn babies, according to work done by Plymouth researchers. A report published yesterday by the universities of Plymouth and Ulster raises a number of concerns about the way antenatal screening is carried out across the country. The report concludes: "There are significant groups of parents who are being given insufficient opportunity to consider...
