What causes maple syrup syndrome?

Maple syrup syndrome, or Maple Syrup Urine Disease (MSUD), is an extremely uncommon genetic disorder affecting approximately 1 in 185,000 newborns. It is caused by genetic mutations that inhibit the production of enzymes responsible for breaking down three specific amino acids found in proteins: leucine, isoleucine, and valine.

These genetic alterations prevent the body from properly metabolizing these amino acids, resulting in the accumulation of toxic substances. The condition gets its name from the distinctive sweet, maple syrup smell of the affected individual's urine.

If left untreated, MSUD can lead to severe neurological problems, developmental delays, and even death. However, early detection and careful management can greatly improve the outcomes for individuals with this condition.
