Prader-Willi children may receive relief from sleep disorders after adenotonsillectomy

Children with Prader-Willi syndrome may receive relief from sleep disorders after undergoing an adenotonsillectomy, suggests a new study from Nationwide Children's Hospital published in the November print issue of the Archives of Otolaryngology-Head and Neck Surgery.

People with Prader-Willi Syndrome may have impaired autonomic nervous system

An Australian study reveals that people with the rare genetic disorder known as Prader-Willi Syndrome may have an impaired autonomic nervous system. This discovery opens up a new way of looking at the insatiable appetite experienced by all sufferers, as well as their very high risk of cardiovascular disease.

Brains of people with anorexia and obesity are wired differently

The brains of people with anorexia and obesity are wired differently, according to new research. Neuroscientists for the first time have found that how our brains respond to food differs across a spectrum of eating behaviors - from extreme overeating to food deprivation.

Oxytocin hormone holds promise for children with Prader-Willi syndrome

Prader-Willi syndrome is a rare genetic disorder which affects one child in 25,000. Children born with this syndrome have a range of complex neurological and developmental problems which continue into adult life. These can manifest as cognitive and behavioral difficulties, weight gain, problems in controlling their temper and attendant difficulties in socialization.

Scientists discover simple molecular test to block GOAT enzyme

Scientists at The Scripps Research Institute have designed a new molecular test that will allow researchers to look for potential drugs targeting a human metabolic enzyme believed to stimulate the appetite and play a role in diabetes.

New resources to support Teva Pharmaceutical Industries' Tjet injector system now available

Teva Pharmaceutical Industries Ltd. announced today the availability of new resources to support the recently introduced Tjet® injector system, a needle-free device designed to deliver Teva’s TEV-TROPIN® [somatropin (rDNA origin) for injection] brand human growth hormone (hGH) to children who have growth failure due to inadequate secretion of normal endogenous growth hormone.

NORD urges members of Congress to pass comprehensive health reform legislation

On behalf of the 30 million Americans who are affected by one of the nearly 7,000 rare disorders, the National Organization for Rare Disorders (NORD) urges you to pass comprehensive health reform legislation to assure that every American has access to affordable, meaningful health insurance coverage. Failure to pass such long-overdue legislation this year would be devastating for people with rare diseases, and for millions of others burdened by chronic illness.

Analysis suggests human development is set by ongoing interplay of parent and offspring genes

An analysis of rare genetic disorders in which children lack some genes from one parent suggests that maternal and paternal genes engage in a subtle tug-of-war well into childhood, and possibly as late as the onset of puberty.

New technique provides closer look at DNA and mRNA

In a study in the advance online edition of Nature Structural and Molecular Biology, researchers from Albert Einstein College of Medicine describe a technique for looking more precisely at a fundamental step of a cell's life - a gene, DNA, being read into a message, mRNA.

Boys are twice as likely as girls in the U.S. and Asia to receive growth hormone

Boys are twice as likely as girls in the U.S. and Asia (mostly Japan) to receive recombinant human growth hormone (rhGH) for growth hormone deficiency, illnesses that affect height, and short stature of a non-medical nature.

Overall genome landscape between chimps and humans can be attributed to large segmental duplications

A study comparing the genomes of both humans and chimpanzees has found that much of the genetic difference between the two species came about in events called segmental duplications, in which segments of genetic code are copied many times in the genome.
