Cer(d18:1/18:0)

lipid

Cer(d18:1/18:0) amplifies lipid retention and inflammatory signaling in atherosclerotic plaques, predicting adverse thrombotic events.

Pathway placement
Cascade stepLipid retention & oxidation
Confidencehigh
RationaleCeramide directly associated with CAD severity and recurrent ACS; pro-inflammatory lipid species driving atherosclerotic burden.

Druggability
Not assessed (no mapped human gene target).

Specificity differential (R−C)-17.9
Non-Type-I axis panel
Does this marker also move in each non-Type-I setting? mag 0–3; higher means less Type-I-specific. n/a = no evidence retrieved, which is not the same as no change.
No non-Type-I axis evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
