ACADM and medium chain acyl-CoA dehydrogenase deficiency: Further, three (75%) heterozygous infants had five mutations for MCAD deficiency, including two novel mutations c.589A > G and c.1248T > G, and three reported mutations c.449_452delCTGA, c.970G >A, and c.1238G > A in ACADM gene, and one (25%) is heterozygous for the novel mutation c.790G > T. Until now, three infants with MCAD deficiency were treated with levocarnitine and referred to control of low fat intake and no fasting, and all of them are asymptomatic.
