Although the underling enzyme deficiency associated with SLOS is clear there are likely to be multiple mechanisms responsible for SLOS pathology. In an effort to learn more of the aetiology of SLOS we have analysed plasma from SLOS patients to search for metabolites derived from 7-DHC which may be responsible for some of the pathology. We have identified a novel hydroxy-8-dehydrocholesterol, which is either 24- or 25-hydroxy-8-dehydrocholesterol and also the known metabolites 26-hydroxy-8- dehydrocholesterol, 4-hydroxy-7-dehydrocholesterol, 3b,5a-dihydroxycholest-7-en-6-one and 7a,8aepoxycholesterol. None of these metabolites are detected in control plasma at quantifiable levels (0.5 ng/ mL). date: 2017-05 date_type: published publisher: PERGAMON-ELSEVIER SCIENCE LTD official_url: http://doi.org/10.1016/j.jsbmb.2016.03.018 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1120547 doi: 10.1016/j.jsbmb.2016.03.018 lyricists_name: Clayton, Peter lyricists_name: Tuschl, Karin lyricists_id: PTCLA52 lyricists_id: KTUSC04 actors_name: Clayton, Peter actors_name: Laslett, David actors_id: PTCLA52 actors_id: DLASL34 actors_role: owner actors_role: impersonator full_text_status: public publication: The Journal of Steroid Biochemistry and Molecular Biology volume: 169 pagerange: 77-87 pages: 11 issn: 0960-0760 citation: Griffiths, WJ; Abdel-Khalik, J; Crick, PJ; Ogundare, M; Shackleton, CH; Tuschl, K; Kwok, MK; ...
