While classically considered a disease of grey matter, recent imaging data have revealed presymptomatic abnormalities in white matter (WM) tracts. Here, we report lipid changes in glycerophospholipids and sphingolipids from enriched myelin extracts of three WM tracts (internal capsule (IC), dorsomedial prefrontal cortex (dmPFC), corpus callosum (CC)) of HD and control donors. We found no difference in total lipid concentration between HD and control myelin. However, changes were observed at the lipid class level for the CC and dmPFC, with a reduction in the proportion of Hexosylceramides in HD myelin. When lipids were examined at a species level, there was a shift towards shorter glycerophospholipid fatty acid chain length in HD for all three regions, most notably in phosphatidylethanolamine species. This coincides with previous data showing a reduction in fatty acyl chain lengths in sphingolipid species in the caudate of the same donor cohort and suggests a widespread impact of HD on fatty acid metabolism in the brain.\n
