Expanding the clinical spectrum of primary coenzyme Q10 deficiency type 6: The first case with cardiomyopathy

Abstract

We report a 19-month-old patient with cardiomyopathy as the first presenting feature of primary COQ10 deficiency-6. This case expands the phenotypic spectrum of this disorder. Furthermore, it shows that genetic testing for primary COQ10 deficiency should be considered in patients with pediatric-onset cardiomyopathy as it can guide treatment options.
