Druggability
Not assessed (no mapped human gene target).
Type I vs Type II discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I33
C — confounder / Type-II60
A — assay feasibility68
E — evidence strength23
T1DI (composite)6
Specificity differential (R−C)-26.7
Confounder panel (Type-II drivers)
No confounder evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
Assay & specimen

Method / principle
Sandwich immunoassay (ELISA) — research-grade unless a cleared assay exists
Reagent / substrate
Matched anti-target antibody pair (capture + labeled detection)
Platform
ELISA microplate or multiplex (Luminex/MSD)
Turnaround · availability
Send-out / research · Research-grade (no universal clinical assay)
