描述
Short Chain Acyl CoA Dehydrogenase Deficiency (SCAD Deficiency) is caused by mutation in the gene encoding short-chain acyl-CoA dehydrogenase, an enzyme which normally breaks down short chain fatty acids. SCADD causes accumulation of ammonia in blood; butyrylcarnitine(C4) in plasma; adipic acid, butyrylglycine, ethylmalonic acid; hexanoylglycine and methylsuccinic acid in urine. Symptoms include hypoglycemia, hypotonia, microcephaly, failure to thrive, lactic acidosis, peripheral neuropathy, and vomiting.
