Indeed, hypertrophic and dilated cardiomyopathy are frequent findings in patients with deficiencies at the level of CACT, CPT2, VLCAD, and LCHAD/MTP, but not CPT1A, which follows logically from the fact that CPT1B and not CPT1A is the predominant CPT expressed in heart muscle. Here, CPT1A is linked to dilated cardiomyopathy.
