Sex hormone-binding globulin
SHBGproteinSHBG is a systemic CAD-risk modifier that regulates sex-hormone bioavailability and influences metabolic and vascular health independent of atherothrombotic cascade steps.

Confidencemedium
RationaleSystemic CAD risk modifier; endocrine/metabolic axis; not direct cascade step.
Druggability
Not assessed (no mapped human gene target).
Type I vs non-Type I discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I59
C — non-Type-I57
A — assay feasibility68
E — evidence strength26
T1DI (composite)9
Specificity differential (R−C)+2.5
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.
