Résumé
Increased risk of venous thromboembolism (VTE) is a life-threatening side effect for users of oral contraceptives (OCs) or hormone therapy (HT). To investigate the potential for genetic predisposition to VTE in OC or HT users, we conducted a gene-by-environment (GxE) case-only meta-analysis of genome-wide association studies (GWAS). Use or non-use of OCs (7 studies) or HT (8 studies) at the time of the VTE event was determined by pharmacy records or self-report. A synergy index (SI) was modeled for each variant in each study and estimated supra-multiplicative GxE interaction. The SI parameters were first meta-analyzed across OC and HT studies, and subsequently meta-analyzed to obtain an overall estimate. The primary analysis was agnostic GWAS and interrogated all imputed genotypes using a p-value threshold of <5.0x10 The VTE case-only OC meta-analysis included 2,895 OC users and 6,607 non-users; the case-only HT meta-analysis included 2,434 HT users and 12,793 non-users. In primary GWAS meta-analyses, no variant reached genome-wide significance, but the smallest p-value approached statistical significance: rs9386463 (p = 5.03x10 The candidate-variant approach to identify supra-multiplicative associations between genetic variation and OC-HT use identified a new association with common genetic variation in F11 while the agnostic interrogations did not yield new discoveries.

BACKGROUND
BACKGROUND
Increased risk of venous thromboembolism (VTE) is a life-threatening side effect for users of oral contraceptives (OCs) or hormone therapy (HT).
OBJECTIVES
OBJECTIVE
To investigate the potential for genetic predisposition to VTE in OC or HT users, we conducted a gene-by-environment (GxE) case-only meta-analysis of genome-wide association studies (GWAS).
METHODS
METHODS
Use or non-use of OCs (7 studies) or HT (8 studies) at the time of the VTE event was determined by pharmacy records or self-report. A synergy index (SI) was modeled for each variant in each study and estimated supra-multiplicative GxE interaction. The SI parameters were first meta-analyzed across OC and HT studies, and subsequently meta-analyzed to obtain an overall estimate. The primary analysis was agnostic GWAS and interrogated all imputed genotypes using a p-value threshold of <5.0x10
RESULTS
RESULTS
The VTE case-only OC meta-analysis included 2,895 OC users and 6,607 non-users; the case-only HT meta-analysis included 2,434 HT users and 12,793 non-users. In primary GWAS meta-analyses, no variant reached genome-wide significance, but the smallest p-value approached statistical significance: rs9386463 (p = 5.03x10
CONCLUSIONS
CONCLUSIONS
The candidate-variant approach to identify supra-multiplicative associations between genetic variation and OC-HT use identified a new association with common genetic variation in F11 while the agnostic interrogations did not yield new discoveries.
