Abstract: Three infants with documented mitochondrial fatty acid oxidation disorders are described in this report. Case 1. Carnitine/acylcarnitine translocase deficiency. (CACT) (OMIM 212138) A two-day-old male developed sudden cardiac arrest 48 hours postpartum, with a previous history of early death (day 2) in siblings with a history of parental consanguinity; somnolence, inactivity, refusal to suck within 24 h, hepatomegaly, persistent hypoglycemia, hypocalcemia, hyperkalemia and severe metabolic acidosis prior to cardiac arrest. Dried blood spots by tandem mass spectrometry demonstrated 10 × elevation of palmitoylcarnitine, moderate elevation of oleylcarnitine, steroylcarnitine and myristoylcarnitine. Case 2. Medium chain acyl CoA dehydrogenase (MCAD) deficiency. (OMIM 212139) A six-week-old male infant, developed sudden cardiac arrest after contacting a viral illness, resuscitated successfully in the first episode, only to succumb during the second episode, 2 weeks apart. Plasma acylcarnitine via tandem mass spectrometry was reported normal; however, urine organic acids via gas liquid chromatography and mass spectrometry demonstrated characteristic metabolites consistent with MCADD. Case 3. Carnitine deficiency, systemic primary. (CDSP) (OMIM 212140) A one-year-old girl with progressive dyspnea since birth and a history of parental consanguinity. Severe dilated cardiomyopathy with episodes of cardiac decompensations, hepatomegaly, anemia, generalized hypotonia, but no hypoglycemia were demonstrated prior to cardiac arrest. Extremely low carnitine level noted in dried blood spots via tandem mass spectrometry.
