Formatted abstract Aims:
Conduct an Australian-based analysis of the angiotensinogen-6 variant in two independent inflammatory bowel disease (IBD) cohorts, and examine the role of angiotensinogen-6 and TGFß1 codon 25 variants in shaping Crohn’s disease phenotype.

Methods:
IBD Patients (Crohn’s disease = 347, ulcerative colitis = 147) and CD families (n = 148) from two cohorts, together with 185 healthy controls were genotyped for angiotensinogen-6. Genotype-phenotype analyses were performed for both angiotensinogen-6 and TGFß1 codon 25.

Results:
Angiotensinogen-6 AA genotype was significantly associated with Crohn's disease (p = 0.007, OR = 2.38, CI = 1.32–4.32) in cohort 1, but not in the smaller cohort 2 (p = 0.19). The association remained significant when the two cohorts were combined (p = 0.008), and in a TDT family analysis (p = 0.03). TGF 1 codon 25 was associated with stricturing Crohn’s disease (p = 0.01, OR = 2.63, CI = 1.16–5.88) and a shorter time to intestinal resection (p = 0.06).

Conclusions:
The association of the angiotensinogen-6 variant with Crohn’s disease supports a potential role for angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists in disease treatment.
