ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical features and gene mutations in an adolescent patient affected with late-onset multiple aeyl-CoA dehydrogenase deficiency (MADD) with severe fatty liver.</p><p><b>METHODS</b>Potential mutations of the ETFDH gene were detected with polymerase chain reaction (PCR) and DNA sequencing.</p><p><b>RESULTS</b>The 13-year-and-10-month girl has presented with weakness without any other special manifestation. Laboratory tests demonstrated an elevation of myocardial enzyme levels, total cholesterol, lactic acid and abnormal serum free fatty acids. H magnetic resonance spectroscopy revealed severe fatty liver. An increase in multiple plasma acyl-carnitines was detected by gas chromatography/mass spectrometry and isobutyrylglycine in urine by screening with tandem mass spectrometry. Genetic analysis demonstrated 2 heterozygous missense mutations c.250G>A (p.Ala84Thr) and c.353G>T (p.Cys118Phe) in the ETFDH gene. The diagnosis of MADD was confirmed. The patient was given large dose of vitamin B2, which resulted in rapid clinical and biochemical improvement.</p><p><b>CONCLUSION</b>A common mutation c.250G>A and a novel mutation c.353G>T in the ETFDH gene were identified in the patient. The pathogenic role of c.353G>T (p.Cys118Phe) deserves further study. Early diagnosis of MADD and appropriate therapy is crucial for the prognosis.</p>
