title: Hereditary hyper-ACE-emia due to the Pro1199Leu mutation of somatic ACE as a potential pitfall in diagnosis: a first family outside Europe.
abstract: Elevated plasma levels of angiotensin converting enzyme (ACE) are associated with granulomatous diseases. However, several families of autosomal dominant hyper-ACE-emia without disease association have already been reported. Recently, the ACE mutation c.3705C>T (Pro1199Leu) was identified as the genetic correlate in European cases of asymptomatic autosomal dominant hyper-ACE-emia. Here, we describe a first family outside Europe with asymptomatic autosomal-dominant hyper-ACE-emia due to the ACE Pro1199Leu mutation. Benign autosomal-dominant hyper-ACE-emia should be considered for differential diagnosis of elevated ACE levels worldwide.
