Sebum is a biofluid excreted by sebaceous glands in the skin. In recent years sebum has been shown to contain endogenous metabolites diagnostic of disease, with remarkable results for Parkinson’s Disease. Given that sebum sampling is facile and non-invasive, its potential for use in clinical bioc...

Background Variants in the β-glucocerebrosidase (GBA1) gene are the commonest genetic risk factor for Parkinson Disease (PD). Here, we use mass spectrometry based metabolomics to analyse serum and sebum samples from 50 genotyped participants and find differences in lipid and sugar reg...

Parkinson's Disease (PD) has been associated with a distinct odour, which emanates from the skin and is strongest in sebum-rich areas. In this study, sebum was sampled from participants using cotton gauze and the volatile components emanating from these swabs were analysed directly with thermal d...
