First proof of how the rare disorder Fanconi anemia causes chromosomal instability

The scientists found a gene mutation not previously known to be related to Fanconi anemia, and they say that BRIP1 is the first gene associated with the disease whose protein has a known function.

Researchers have discovered a gene linked to age-related maculopathy

University of Pittsburgh researchers have discovered a gene linked to age-related maculopathy (ARM), the leading cause of untreatable blindness in the elderly. Their discovery suggests a simple test might be able to identify those at risk for what is commonly known as macular degeneration (AMD) and may lead to the development of more effective preventive strategies.

Placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases as embryonic stem cells

Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express.

First evidence that complex genetic interactions account for autism risk

Using a novel analysis of the interactions among related genes, Duke University Medical Center researchers have uncovered some of the first evidence that complex genetic interactions account for autism risk. The Duke team found that the brain mechanism that normally stops or slows nerve impulses contributes to the disease.

Customized gene chip offers clues to prognosis in cases of neuroblastoma

Rather than covering the entire genome, the microarray focuses on suspect regions of chromosomes for signs of deleted genetic material known to play a role in the cancer.

Customized gene chip will offer clues to prognosis in cases of neuroblastoma

Genetics researchers have developed a customized gene chip to rapidly scan tumor samples for specific DNA changes that offer clues to prognosis in cases of neuroblastoma, a common form of children's cancer.

Exposure to second-hand smoke during pregnancy can be just as detrimental to a developing fetus as primary exposure through maternal smoking

In a study published in the online journal BMC Pediatrics, Stephen G. Grant, Ph.D., associate professor of environmental and occupational health, reports that both active maternal smoking and secondary maternal exposure result in similarly increased rates of genetic mutation that are basically indistinguishable.

Multi-species genome comparison sheds new light on evolutionary processes

An international team that includes researchers from the National Human Genome Research Institute (NHGRI) has discovered that mammalian chromosomes have evolved by breaking at specific sites rather than randomly as long thought - and that many of the breakage hotspots are also involved in human cancer.

Scientists have identified the first genetic mutations that cause the aorta to widen, tear and rupture

Finding biological markers that flag aneurysm, a bulging of the aorta that leads to dissection, a lengthwise separation of tissues in the artery wall, is critically important for early diagnosis.

Gene that regulates normal embryonic development is found at high levels in virtually all forms of breast cancer

A gene that appears to help regulate normal embryonic development is found at high levels in virtually all forms of breast cancer, according to a new study led by Laszlo Radvanyi, Ph.D., associate professor of breast and melanoma medical oncology at The University of Texas M. D. Anderson Cancer Center.

New insight into age-related macular degeneration

Age-related macular degeneration is the leading cause of blindness in older adults, yet researchers are still in the dark about many of the factors that cause this incurable disease.

Multiple rare mutations within a single gene may increase risk for autism

While debate still rages over the 'cause' of autism, mounting evidence suggests that genetic factors play a major role in the disease.

Hidden secrets on the nature and timing of genome evolution in mammals revealed

Breakages in chromosomes in mammalian evolution have occurred at preferred rather than random sites as long thought, and many of the sites are involved in human cancers, an international team of 25 scientists has discovered.

Two regions of the human genome that appear to explain variation in IQ

It may be that IQ tests are not the only way to measure human intelligence. Scientists at The Queensland Institute of Medical Science (QIMR) have identified two regions of the human genome that appear to explain variation in IQ. Their work was published this week in the American Journal of Human Genetics and has drawn world-wide interest.

Extraordinary number of genes are required for prenatal mammalian development

A team of scientists led by Cornell University's Dr. John Schimenti reports today that an extraordinary number of genes are required for prenatal mammalian development. The researchers estimate that up to 19% of all genes are vital for embryogenesis in mice.

Chromos Molecular Systems issued four key patents

Chromos Molecular Systems has announced that it has further expanded the patent portfolio surrounding both its ACE System and REM Technology with the issuance of four key additional patents.

Researchers find genetically controlled brain mechanism responsible for social behavior in humans

Researchers at the National Institute of Mental Health (NIMH) have discovered a genetically controlled brain mechanism responsible for social behavior in humans--one of the most important but least understood aspects of human nature.

Researchers have pinpointed specific gene and protein over-production in metastatic melanoma

Gene amplification is a process that often happens in cancer cells when the normal DNA replication process is altered, causing many copies of the gene to be produced instead of a single copy of a region of a chromosome.

Researchers discover genetically controlled brain mechanism responsible for social behavior in humans

Researchers at the National Institute of Mental Health (NIMH) have discovered a genetically controlled brain mechanism responsible for social behavior in humans - one of the most important but least understood aspects of human nature. The findings are reported in Nature Neuroscience.

Changes to prenatal genetic testing could mean more babies born with abnornalities

A study in the UK suggests that a proposed change to the type of prenatal genetic testing offered to couples in the UK, could possibly result in certain chromosome abnormalities being missed.
