Is Maple syrup urine disease dominant?

Answer 1

It is an autosomal recessive condition.

MSUD is an autosomal-recessive disorder, with an incidence of 1 in 120 000 to 1 in 500 000. It is highly prevalent in the inbred Mennonite population in Pennsylvania, occurring in approximately 1 in 176 newborns. In countries where consanguineous marriages are common the frequency is also higher (about 1 in 50 000 in Turkey). About 75% of those affected suffer from the severe classic form, and the remainder suffer from the milder intermediate or intermittent variants. Over 150 different causal mutations scattered among the three E1α, E1β, and E2 genes give rise to either classic or intermediate clinical phenotypes.

Answer 2

MSUD occurs when a persons metabolism cannot break down certain proteins and amino acids. These chemicals, especially, are leucine, isoleucine, and valine. In a result of this, when a person with MSUD urinates, it can smell like maple syrup.
