Abstract:
Patients carrying Acyl-CoA dehydrogenase 9 (ACAD9) mutations reported to date mainly present with severe hypertrophic cardiomyopathy and isolated complex I (CI) dysfunction. Here we report a novel ACAD9 mutation in a young girl presenting with severe hypertrophic cardiomyopathy, isolated CI deficiency and interestingly multiple respiratory chain complexes assembly defects. We show that ACAD9 analysis has to be performed in first intention in patients presenting with cardiac hypertrophy even in the presence of multiple assembly defects.
