ABSTRACT
OBJECTIVE:
The aim of this study was to investigate if there is a causal relationship between circulating levels of TIM-1 (T-cell immunoglobulin and mucin domain 1) and incidence of stroke. Approach andResults:
Plasma TIM-1 was analyzed in 4591 subjects (40% men; mean age, 57.5 years) attending the Malmö Diet and Cancer Study. Incidence of stroke was studied in relation to TIM-1 levels during a mean of 19.5 years follow-up. Genetic variants associated with TIM-1 (pQTLs [protein quantitative trait loci]) were examined, and a 2-sample Mendelian randomization analysis was performed to explore the role of TIM-1 in stroke using summary statistics from our pQTLs and the MEGASTROKE consortium. A total of 416 stroke events occurred during follow-up, of which 338 were ischemic strokes. After risk factor adjustment, TIM-1 was associated with increased incidence of all-cause stroke (hazards ratio for third versus first tertile, 1.44 [95% CI, 1.10-1.87]; P for trend, 0.004), and ischemic stroke (hazards ratio, 1.42 [95% CI, 1.06-1.90]; P for trend, 0.011). Nineteen independent lead SNPs, located in three genomic risk loci showed significant associations with TIM-1 (P<5×10-8). A 2-sample Mendelian Randomization analysis suggested a causal effect of TIM-1 on stroke (ß=0.083, P=0.0004) and ischemic stroke (ß=0.102, P=7.7×10-5).CONCLUSIONS:
Plasma level of TIM-1 is associated with incidence of stroke. The genetic analyses suggest that this could be a causal relationship.Palabras clave
