Neuroscientists identify key role of language gene

Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans' unique ability to produce and understand speech. Researchers from MIT and several European universities have shown that the human version of a gene called Foxp2 makes it easier to transform new experiences into routine procedures.

Intersection of population variation and autoimmunity genetics in human T cell activation

T lymphocyte activation by antigen conditions adaptive immune responses and immunopathologies, but we know little about its variation in humans and its genetic or environmental roots. We analyzed gene expression in CD4+ T cells during unbiased activation or in T helper 17 conditions from 348 healthy participants representing European, Asian, and African ancestries.

Genetics reveals patients susceptible to drug-induced pancreatitis

It has long been recognized that about four per cent of patients who are prescribed particular drugs for IBD go on to develop pancreatitis, an inflammation of the pancreas, which can be fatal. Now researchers have found that 17 percent of patients who have two copies of a particular genetic marker are likely to go on to develop pancreatitis if they are prescribed thiopurine drugs.

Genetics of Osteogenesis Imperfecta and Phenotypic Implications

Osteogenesis imperfecta , a skeletal disorder caused by mutations in type I collagen, exhibits structural and functional differences on a genotypic level that contribute to diverse phenotypes. Brendan Lee, MD, PhD, from the Baylor College of Medicine discussed the genetics of OI and homeostatic mechanisms in the skeleton at the 2014 American Society of Bone and Mineral Research Conference in Houston, Texas.

A link between Jacobsen syndrome and autism

A rare genetic disorder known as Jacobsen syndrome has been linked with autism, according to a recent joint investigation by researchers at San Diego State University and the University of California, San Diego. In addition to suggesting better treatment options for people with Jacobsen syndrome, the finding also offers more clues into the genetic underpinnings of autism.

Schizophrenia is eight different diseases, not one

New research shows that schizophrenia is not a single disease, but a group of eight distinct disorders, each caused by changes in clusters of genes that lead to different sets of symptoms. The finding sets the stage for scientists to develop better ways to diagnose and treat schizophrenia, a mental illness that can be devastating when not adequately managed, says C. Robert Cloninger, co-author of the study published today in the American Journal of Psychiatry.

Primary open-angle glaucoma is a leading cause of blindness worldwide. Using genome-wide association single-nucleotide polymorphism data from the Glaucoma Genes and Environment study and National Eye Institute Glaucoma Human Genetics Collaboration comprising 3,108 cases and 3,430 controls, we assessed biologic pathways as annotated in the KEGG database for association with risk of POAG.

*The Queen of DNA*

Prof. Mary-Claire King, one of the world's leading medical geneticists and a good friend of Israel, has won a prestigious award that often leads to the Nobel. She concedes that she was pretty good at math but not enough for a career as a theoretician, did not do well in laboratory work and lacked the drive and interest to become a physician.

Molecular genetics of mouse serotonin neurons across the lifespan.

New molecular genetics approaches have been developed over the past several years to study brain serotonin neuron development and the roles of 5-HT neurons in behavior and physiology. These approaches were enabled by manipulation of the gene encoding the Pet-1 ETS transcription factor whose expression in the brain is restricted to developing and adult 5-HT neurons.

A comparative phenotypic and genomic analysis of C57BL/6J and C57BL/6N mouse strains

BACKGROUND:The mouse inbred line C57BL/6J is widely used in mouse genetics and its genome has been incorporated into many genetic reference populations. More recently large initiatives such as the International Knockout Mouse Consortium are using the C57BL/6N mouse strain to generate null alleles for all mouse genes.

Corn spots: Study finds important genes in defense response

When corn plants come under attack from a pathogen, they sometimes respond by killing their own cells near the site of the attack, committing "cell suicide" to thwart further damage from the attacker. This cell sacrifice can cause very small, often microscopic, spots or lesions on the plant.

Should All Ashkenazi Women Get Tested for BRCA Gene Mutations?

The study indicates that even Ashkenazi women with no family history of the disease but who test positive for a cancer-causing genetic mutation have high rates of breast and ovarian cancer. At the heart of the dispute is the question of whether all women of Ashkenazi Jewish descent should now get genetic testing to determine if they have the mutations of the BRCA1 or BRCA2 gene.
