This is part three in the series for Metabolic Disease Awareness Week. It focuses on Maple Syrup Urine Disease or as it is commonly called MSUD.
MSUD has an incidence rate of 1 in 250,000 people in the UK (this is similar to the US): it is inherited in a autosomal recessive manner. This means that the parents of the affected child carry a genetic trait that causes MSUD. There is a 25% chance of having a child with MSUD if both parents are carriers.
