Short-chain acyl-CoA dehydrogenase deficiency is an extremely rare inherited disorder of fat metabolism belonging to a group of diseases known as fatty acid oxidation disorders (FOD); It occurs because of a deficiency of an enzyme;The enzyme, known as short-chain acyl-CoA dehydrogenase enzyme, is involved in the breakdown of complex fatty acids into more simple substances; This takes place in the cell’s mitochondria, small, well-defined bodies found in all cells in which energy is generated from the breakdown of complex substances into simpler ones (mitochondrial oxidation); When this enzyme is deficient, excessive amounts of fatty acids accumulate in the liver and muscle tissues, and ammonia and other products accumulate in the blood and body tissues;Although SCAD was initially thought to produce severe problems including progressive muscle weakness, hypotonia, acidemia, developmental delay, and even early death, it is now believed that this disorder is both more common and less severe in many cases than originally thought at the time of its discovery 20 years ago;Since the advent of expanded newborn screening programs using tandem mass spectrometry technology, many more SCAD infants are being detected, many of whom are well and asymptomatic;When symptoms are present, they tend to appear soon (days to weeks) after birth and include lack of weight gain, general failure to thrive, vomiting, and poor feeding;NORD 2005]
