Sphingosine

lipid

Sphingosine dysmetabolism contributes to lipid accumulation and oxidative stress in atherosclerotic plaque and myocardial injury.

Druggability
Not assessed (no mapped human gene target).

Type I vs Type II discrimination

ScoresLow-confidence (proxy)
R — rupture / Type-I
66
C — confounder / Type-II
93
A — assay feasibility
40
E — evidence strength
35
T1DI (composite)
5
Specificity differential (R−C)-27.7
Confounder panel (Type-II drivers)
No confounder evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
