Prader-Willi syndrome (PWS) is caused by a loss of genes normally expressed only from the paternal chromosome 15. About 70% of PWS cases arise from Type 1 and Type 2 deletions, which are about 5 million DNA base pairs in size. Genetic mapping data from unique patients harboring smaller deletions, “microdeletions”, in the PWS region implicate the...
Obesity and insatiable appetite (hyperphagia) are among the most serious symptoms experienced by Prader-Willi syndrome (PWS) patients. While many of the causes underlying PWS symptoms remain unknown, the discovery of the protein hormone ghrelin and its role in controlling appetite has led researchers to investigate the possible role of ghrelin in...
Prader-Willi Syndrome (PWS) is a neurodevelopmental disorder caused by lack of inherited genes from fathers on chromosome 15. PWS is characterized by intellectual disabilities, repetitive and compulsive behaviors, social cognition deficits, increased eating and obesity. These individuals typically consume up to three times the normal caloric...
The vagus nerve is a major route of communication between the brain and the gut. Vagus nerve stimulation (VNS) is a procedure whereby a small implanted device placed under the skin on a patient’s chest delivers an intermittent electrical impulse to the vagus nerve, which will travel up and down the nerve and into the brain and to the gut. VNS has...
