Female induced pluripotent stem (iPS) cells, reprogrammed from human skin cells into cells that have the embryonic-like potential to become any cell in the body, retain an inactive X chromosome, stem cell researchers at UCLA have found. The finding could have implications for studying X chromosome-linked diseases such as Rett syndrome, caused by mutations in a gene located on the X chromosome. The findings differ from those seen in mouse skin cells that are reprogrammed into iPS cells, in...

A genetics research team based at The Children's Hospital of Philadelphia continues to discover recurrent translocations"”places in which two chromosomes exchange pieces of themselves. As many as 1 in 600 persons carry balanced chromosome translocations, which involve no loss or gain of DNA. Most such people appear healthy, but may have a child with abnormal chromosome composition and disabilities resulting from disrupted, extra or missing copies of genes. While rare, such diseases...

SEATTLE, July 21 /PRNewswire/ -- A Seattle-area mother and her four-month-old daughter represent a tiny number of births nationwide - perhaps among the first three- using a technology that could be the next major advancement in reducing multiple miscarriages. Sheila Gruber, 34, of Duval, had suffered two consecutive miscarriages prior to undergoing a form of in vitro fertilization (IVF) and embryonic analysis that allows geneticists to examine about one-fourth of the entire human genome...

Although clubfoot is one of the most common congenital birth defects, few genetic causes have been found. Now, researchers at Washington University School of Medicine in St. Louis have found what they believe to be the most common cause of inherited clubfoot yet discovered. By performing a routine genetic screening on 66 patients with an inherited form of clubfoot, Christina Gurnett, MD, PhD, a Washington University pediatric geneticist and neurologist at St. Louis Children's Hospital, and...

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...

LONDON, June 30 /PRNewswire/ -- Frost & Sullivan is pleased to announce that it has awarded its prestigious 2010 Scandinavia New Product Innovation Award to FCMB ApS ("FCMB") for its breakthrough work in non-invasive prenatal testing. FCMB is developing a suite of non-invasive prenatal diagnostics based on isolating fetal cells from maternal blood samples. FCMB's diagnostics have the potential to provide results that are as accurate as more invasive procedures, such as amniocentesis...

Researchers from the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and the Max-Planck Institute of Immunobiology Freiburg have identified a novel protein complex that regulates around 4000 genes in the fruit fly Drosophila and likely plays an important role in mammals, too. Published today in Molecular Cell, their findings explain how another regulatory protein can lead a double life. "This new complex seems to be one of the major regulatory complexes both in Drosophila...

Y chromosome linked to fatal aneurysm Research currently being undertaken at the University of Leicester may identify reasons underlying an increased risk of Abdominal Aortic Aneurysms (AAA) in men. In her doctoral study, Cardiovascular Sciences student Lisa Bloomer is looking into the causes of the male predominance of AAA, with a particular emphasis on genetic basis of the disease. Preliminary results from the study will be showcased at the University of Leicester's Festival of Postgraduate...
