rs7080536, also known as c.1601G>A, p.Gly534Glu and G534E, is a variant in the HABP2 gene on chromosome 10. Originally noticed in a group of individuals from Marburg, Germany, the rs7080536(A) allele and corresponding variant protein is also known as the Marburg I (MI) variant. The HBAP2 gene may also be referred to as FSAP (Factor VII Activating Protein or Protease) in some texts.
The rs7080536(A) allele is associated as a risk factor for several conditions, including:
- Carotid stenosis
- A study of 800+ individuals found odds ratio of 6.6 [CI:1.6 - 27.7].[PMID 12578864]
- Clinical stroke
- A study of 8,000 individuals concluded that the Marburg I polymorphism was associated with an increased risk of clinical stroke (HR 1.60, CI: 1.13-2.28) and all-cause mortality (HR 1.33, CI: 1.04-1.71).[PMID 21789270]
- Venous Thromboembolism (VTE)
- In a relatively small study (300 patients, 200 controls), the Marburg I variant was seen as an independent risk factor for VTE (OR 3.5, CI: 1.2-10.0) and also idiopathic VTE (OR 6.2, CI: 2.0-18.9).[PMID 15486068]
- A larger study of ~900 patients determined that the Marburg I variant was associated with the development of deep venous thrombosis (OR 1.65, CI:1.16-2.34) and recurrent thromboembolic events (OR 2.13, CI; 1.35-3.36) OR (95% CI). [PMID 22421107]
- Familial Nonmedullary Thyroid cancer
- Carriers of a Marburg I variant have about a 2x higher risk for thyroid cancer based on a study of 400+ patients. Functional studies indicated that the HABP2 protein may normally have a tumor-suppressive effect, but the G534E variant results in a loss of that function.[PMID 26222560]
[PMID 26691890] The HABP2 G534E variant is an unlikely cause of familial non-medullary thyroid cancer.
