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.
Aims: The aim of this work was to reveal the relation between the ACE gene I/D polymorphism
and acne vulgaris development among a sample of patients.
Patients and Methods: This study included 100 acne vulgaris patients in addition to
120 matched control subjects. The ACE gene I/D polymorphism was analyzed using
polymerase chain reaction (PCR).
Results: The distribution of DD, ID genotypes, and D allele showed higher frequency
in AV patients than in controls (P < 0.001 for all). Moreover, positive family history
and ACEI/D gene polymorphism (DD + ID genotypes) were considered as independent
predictors for severe acne grades (P ≤ 0.001 and 0.046, respectively) in multivariate
analysis.
Conclusions: The current study results suggest that the D allele of the ACE I/D gene
polymorphism might confer risk to AV among the studied patients. Moreover, ACE
I/D gene polymorphism and positive family history were considered as independent
predictors of severe AV. |
