Very long time persistent hyperCKemia as the first manifestation of McLeod syndrome: a case report.

Abstract

McLeod syndrome (MLS) is a very rare genetic X-linked condition due to XK gene mutations and characterized by the development of chorea, psychiatric and cognitive impairment, seizures, cardiomyopathy, muscular involvement and the presence of acanthocytes. We present the case of a patient with very long lasting mild myalgia and elevated creatine kinase (CK) who developed lateonset chorea and was finally diagnosed with MLS.
