Angiotensin-converting enzyme gene insertion/deletion polymorphism and family history in severe acne vulgaris.

Background: Acne vulgaris is an inflammatory disorder with a profound heterogenous aetio-pathophysiology. ACE gene I/D polymorphism affects angiotensin-converting enzyme activities that play a role in inflammation. However, there are no molecular genetic studies investigating the contribution of ACE gene insertion/deletion polymorphism in the genetic background of acne vulgaris.
