About scadh deficiency

What is scadh deficiency?

Short chain acyl-CoA dehydrogenase (SCAD) deficiency is a rare autosomal recessive genetic disorder of fatty acid catabolism belonging to a group of diseases known as fatty acid oxidation disorders (FOD). It occurs because of a deficiency of the short-chain acyl-CoA dehydrogenase (SCAD) enzyme.

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, most of whom are well and asymptomatic.

When symptoms are present, they are variable, ranging from severe, neonatal acidosis to mild developmental delay with hypotonia.



What are the symptoms for scadh deficiency?

Acidemia symptom was found in the scadh deficiency condition

The symptoms of SCAD deficiency include a lack of energy, poor growth, and developmental delay.



What are the causes for scadh deficiency?

 This condition belongs to a group of disorders known as fatty acid oxidation disorders (FOD). SCAD deficiency is caused by mutations in the ACADS gene. These mutations lead to a shortage (deficiency) of an enzyme known as short-chain acyl-CoA dehydrogenase, which is involved in the breakdown of short-chain fatty acids. When not enough of this enzyme is present, excessive amounts of fatty acids and ammonia accumulate in the body.



What are the treatments for scadh deficiency?

Treatment for this condition typically includes a low-fat diet and avoidance of long periods without food (fasting).
