Explorative investigation of the lipids associated with AD on the Baker Institute Lipidomic PheWeb47 showed several associations between fatty acid desaturase 2 (FADS2) and lipids matching the sum composition of lipids such as PC(36:5), PC(P‐38:5)/PC(O‐38:6), PC(32:0), and PC(P‐38:3)/PC(O‐38:4). Here, FADS2 is linked to Alzheimer disease.
