title: Beta-endorphin immunoreactivity in the plasma of patients with the Prader-Labhart-Willi syndrome and their normal siblings.
abstract: No significant difference was found in the range or mean values of ir-beta-endorphin in the plasma of 6 patients with the Prader-Labhart-Willi syndrome compared to 7 of their normal siblings. The hypothesis that some of the symptoms of the P-L-W syndrome are due to excessive opioid activity is not supported by measurement of peripheral levels of ir-beta-endorphin.
