3-hydroxy-3-methylglutaric aciduria (HMG)

3-hydroxy-3-methylgutaric aciduria or HMG lyase deficiency is a metabolic disorder that causes the body to not be able to break down a protein building block (amino acid) that is referred to as leucine. This syndrome also affects the body from making “ketones” which the body uses for energy during fasting, illness or physiological stress.
