Mutations in the HFE gene directly associated with chronic joint disease

Mutations in the HFE gene, which is involved in iron regulation, seem to be directly associated with chronic joint disease (or haemophilic arthropathy) among haemophilic patients, claim a team of Portuguese scientists in the April issue of the journal Blood.

Gene could be cause of early bird disorder

A sleep disorder which makes people nod off early and wake fully alert before dawn is now thought to be caused by a mutant gene.

Autistic children found to have abnormal metabolic profile

Autism, a neurodevelopment disorder which has increased tenfold over the last 15 years, now affects 30 of every 10,000 children in the United States.

Potential therapeutic role for the ataxin-3 protein for Machado-Joseph disease

The repetition of three little "letters" within the gene that codes for the ataxin-3 protein is both the cause of and perhaps a solution to Machado-Joseph disease and an entire family of similar genetic disorders, according to researchers at the University of Pennsylvania.

Location on chromosome 2 that may contain one or more genes that contribute to dyslexia

Researchers trying to tease out the genetic basis of dyslexia have discovered a location on chromosome 2 that may contain one or more genes that contribute to the reading disorder and make it difficult for people to rapidly pronounce pseudowords.

Novel strategy to create a genetic vaccine against P. aeruginosa

Pseudomonas aeruginosa is a bacterium that can cause respiratory tract infections, which can be life threatening in patients who have cystic fibrosis. It is therefore important to develop a vaccine against this pathogen.

Exposure to organochlorine compounds increases the risk of suffering colorectal cancer

A team of researchers at the Universitat Autònoma de Barcelona, The Catalan Institute of Oncology and the Higher Council for Scientific Research (CSIC) have published a study indicating that exposure to organochlorine compounds, which we ingest in our diets, increases the risk of suffering colorectal cancer.

New miniature sensors for analysing DNA

The sensors have the same size and thickness as a fingernail and reduce the time needed to identify DNA chains to several minutes or a few hours, depending on each chain.

Dozens of new genes identified in X chromosome

By intensely and systematically comparing the human X chromosome to genetic information from chimpanzees, rats and mice, a team of scientists from the United States and India has uncovered dozens of new genes, many of which are located in regions of the chromosome already tied to disease.

$Why do black South Africans have a low hip fracture rate despite low calcium intake?$

Why do black South Africans have a low hip fracture rate despite low calcium intake?

After Nelson Mandela was released from prison February 11, 1990, all children born in the great Johannesburg area were enrolled in a 20-year longitudinal study. Officially known as “Birth to Twenty,” the study and its 3,273 youth, are colloquially referred to as “Mandela’s Children.” It’s the largest and longest running study of child and adolescent health and development in Africa, and one of the few large-scale longitudinal studies in the world.

Being a couch potatoe may run in family

So, you don’t like to exercise? Maybe you could blame it on your great-great-grandparents. Similarly, if you’re a practiced and proud couch potato who suddenly woke up to the fact that you’re a “natural” athlete, the credit could also belong to your genes.

SERPINE2 identified as novel candidate gene for COPD susceptibility

Using a combination of genetic linkage, microarray gene expression and genetic association studies, a group of Brigham and Women’s Hospital/ Harvard Medical School researchers have identified a serine protease inhibitor clade E, member 2, or SERPINE2, “as a novel candidate susceptibility gene for COPD,” according to Sorachai Srisuma

Cranberry juice may help protect against heart disease

Protection against a wide variety of diseases is among the many benefits of a diet high in whole fruits and vegetables. Cranberries over the years have been identified with preventing or ameliorating urinary tract infections and playing a positive role gum disease, ulcers and even cancer.

Children with autism have a severely abnormal metabolic profile

Chronic biochemical imbalance is often a primary factor in the development of many complex diseases but a possible metabolic basis for autism has not been well explored. Now Arkansas Children's Hospital Research Institute researchers report for the first time that children with autism have a severely abnormal metabolic profile indicating increased vulnerability to oxidative stress.

Discovery could lead to new drug targets for heart disease

Mice with glowing green hearts have yielded the latest clue in the search for molecules involved in structural heart disease. Vanderbilt University Medical Center investigators found that blocking the activity of a single protein, called CaM kinase, in the mouse heart protects against the damaging effects of a heart attack.

A circadian rhythm gene discovered

A few rare people who consistently nod off early, then wake up wide-eyed much before dawn, can blame a newly-found mutant gene for their sleep troubles, Howard Hughes Medical Institute researchers announced today.

Clinical study of mirror neurons provides insights into autism and other disorders

Seeing is doing – at least it is when mirror neurons are working normally. But in autistic individuals, say researchers from the University of California, San Diego, the brain circuits that enable people to perceive and understand the actions of others do not behave in the usual way.
