Recessive mutations in Middle Eastern families shed light on some U.S. cases BOSTON, Jan. 23, 2013 /PRNewswire-USNewswire/ -- While autism clearly runs in some families, few inherited genetic causes have been found. A major reason is that these causes are so varied that it's hard to find enough people with a given mutation to establish a clear pattern. Researchers at Boston Children's Hospital have pinpointed several inherited mutations--among the first to be identified--through an...

Johns Hopkins study links 1 family's rare gene mutation to brain cell abnormality and mental illness Johns Hopkins researchers have identified a rare gene mutation in a single family with a high rate of schizophrenia, adding to evidence that abnormal genes play a role in the development of the disease. The researchers, in a report published in the journal Molecular Psychiatry, say that family members with the mutation in the gene Neuronal PAS domain protein 3 (NPAS3) appear at high risk...

When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree. The diagram started at a central point with a common ancestor, then the lines spread apart as organisms evolved and separated into distinct species. In the 175 years since, scientists have come to agree that Darwin´s original drawing is a bit simplistic, given that multiple species mix and interbreed in ways he didn´t consider possible (though you can´t fault the guy...

Slime Mold Gets Upper Hand By Cheating
2013-01-09 13:38:37

BioMed Central A 'cheater' mutation (chtB) in Dictyostelium discoideum, a free living slime mold able to co-operate as social organism when food is scarce, allows the cheater strain to exploit its social partner, finds a new study published in BioMed Central's open access journal BMC Evolutionary Biology. The mutation ensures that when mixed with 'normal' Dictyostelium more than the fair share of cheaters become spores, dispersing to a new environment, and avoiding dying as stalk cells....

Autism And Other Disorders May Be Caused By Genetic Hotspot Mutations
2012-12-21 06:47:01

[ Watch the Video: Mutation Hotspots in Autism Genes ] Connie K. Ho for redOrbit.com — Your Universe Online A group of international researchers led by a team of investigators from the School of Medicine at the University of California, San Diego (UCSD), recently revealed a new study that provides signals as to the causes of autism and other related disorders. With the findings, it is possible that there are elevated mutation rates in specific parts of the genome that adds to...

Nobody Is Perfect: Study Shows People Have 400 Genetic Flaws In DNA
2012-12-07 12:45:35

Lawrence LeBlond for redOrbit.com - Your Universe Online Perfection is something that all humans strive for at one time or another, be it scoring a perfect 100 on a test, making the perfect soufflé, having the perfect play in basketball, or even landing the perfect job. For others, perfection is a state of well-being–as in being perfectly healthy. While achieving perfect health may be plausible in sense of how one feels, new research shows that, at the genetic level,...

Biologists at Mainz University achieve repair and read-through of stop mutations responsible for the disease After years of basic research, scientists at Johannes Gutenberg University Mainz (JGU) are increasingly able to understand the mechanisms underlying the human Usher syndrome and are coming ever closer to finding a successful treatment approach. The scientists in the Usher research group of Professor Dr. Uwe Wolfrum are evaluating two different strategies. These involve either the...

Researchers from the University of Geneva demonstrate that, in this type of lesion, the rate of progression from a precancerous state to the tumor stage accelerates over time The causes underlying the development of certain types of common cancers have not yet been elucidated. In order to better determine the origin and the sequence of events responsible for the onset of colon cancer, the teams led by Thanos Halazonetis and Stylianos Antonarakis, professors at the University of Geneva...

Gene Mutations Begin Showing Up In Last 5,000 Years Of Human Evolution
2012-11-29 10:51:10

Lawrence LeBlond for redOrbit.com - Your Universe Online In a world that´s more than 4 billion years old, humans have only existed for a fraction of that–roughly 200,000 years. In those 200,000 years of existence, not a lot is known about genetic mutation until we close in on the last 5 to 10 thousand years. It is within that time that researchers believe nearly 75 percent of gene mutations have occurred, making our DNA distinctly different now than it was way back when. This...
