Maple syrup urine disease (MSUD) is a rare metabolic disorder that some babies are born with. It’s caused by a defect in the enzymes that break down some amino acids. Most newborn babies in the United States have their blood tested for MSUD as part of newborn screening.
What does maple syrup urine disease do to the body?
Maple syrup urine disease (MSUD) is a rare but serious inherited condition. It means the body cannot process certain amino acids (the “building blocks” of protein), causing a harmful build-up of substances in the blood and urine. Normally, our bodies break down protein foods such as meat and fish into amino acids.
What are the symptoms of maple syrup urine disease in adults?
- Urine, sweat, or earwax that smells like maple syrup or burnt sugar. …
- Poor feeding, vomiting, loss of appetite, irritability.
- Sluggish/slow/tiredness and weakness.
- Changes in muscle tone – poor muscle tone, muscle tightness/tension.
What is the life expectancy of someone with maple syrup urine disease?
If untreated, MSUD can lead to seizures, coma, and even death; however by adhering to strict dietary changes, affected individuals have a normal life expectancy . Even with treatment, some people experience episodes of metabolic crisis during times of stress or illness.What are the causes of maple syrup urine disease?
Maple syrup urine disease (MSUD) is inherited, which means it is passed down through families. It is caused by a defect in 1 of 3 genes. People with this condition cannot break down the amino acids leucine, isoleucine, and valine. This leads to a buildup of these chemicals in the blood.
Why does my urine smell like caramel?
Maple syrup urine disease MSUD stops your body from breaking down amino acids, which are needed to maintain bodily functions. This disease is diagnosed in infancy using urinalysis, genetic testing, and newborn screening methods. Common symptoms are: urine that smells sweet, like caramel or maple syrup.

Maple syrup urine disease is treatable when found early. Doctors will closely watch kids who have it. Some people with MSUD may have episodes of metabolic crisis.
What foods can make you smell like maple syrup?
If you have eaten curry, you have probably tasted fenugreek. The seeds of this plant as well as its fresh leaves are commonly used as ingredients in curries. They are added for taste but they also impart a smell that is due to sotalone, a compound that at low concentrations has a distinct maple syrup-like odour.Can maple syrup urine disease go undiagnosed?
While newborn screening programs allow for early detection of classic MSUD, cases of the intermittent form might go undetected, and present later in childhood following metabolic derailment, with an array of non-specific symptoms.
What can people with maple syrup urine disease eat?Individuals with MSUD must remain on a protein-restricted diet that limits the amount of branched-chain amino acids they can eat. Protein-restriction must start as soon as possible after birth to promote proper growth and development.
Article first time published onWhy does my son's pee smell like maple syrup?
Maple syrup urine disease is a genetic disorder where a person cannot process certain proteins. It is an inherited disorder, and a parent may notice their baby or child has sweet-smelling urine. This disorder may be fatal if left untreated. It is possible for children to develop less severe forms of the disorder.
How is Niemann Pick disease inherited?
The Niemann-Pick gene mutations are passed from parents to children in a pattern called autosomal recessive inheritance. This means that both the mother and the father must pass on the defective form of the gene for the child to be affected. Niemann-Pick is a progressive disease, and there is no cure.
What does it mean when a baby smells like maple syrup?
WHAT IS MSUD? MSUD stands for “maple syrup urine disease.” It is named for the sweet maple syrup smell of the urine in untreated babies. This condition is one type of amino acid disorder. People with MSUD have problems breaking down certain amino acids found in protein.
Is maple syrup urine disease tested at birth?
Routine newborn metabolic screening for maple syrup urine disease (MSUD) has been available since 1964. This screening is performed in all 50 United States and in various parts of the world. The test is performed within 24-48 hours following birth.
What vitamin makes you smell like maple syrup?
Supplementing fenugreek may cause body secretions, including urine, to smell like maple syrup. This is due to a metabolite called sotolon.
How is maple syrup urine disease prevented?
Since MSUD is an inherited disease, there is no method for prevention. A genetic counselor can help you determine your risk for having a baby with MSUD. Genetic testing can tell you if you or your partner is a carrier of the disease.
Why is MSUD more common in Mennonites?
Though, genetically heterogeneous in the worldwide population, MSUD in Old Order Mennonites (1/150-176) is the result of a tyrosine to asparagine substitution (Y438N; previously Y393N) in the E1alpha subunit of the branched-chain alpha-keto acid dehydrogenase (BCKAD) complex.

Can MSUD be missed on newborn screen?
Newborn screening (NBS) by tandem mass spectrometry (MS/MS) has allowed for early detection and initiation of treatment in many patients with maple syrup urine disease (MSUD) (OMIM 248600), however, a recent report suggests that variants forms may be missed. Information on these patients is limited.
Why do I smell French toast?

What causes Hartnup disease?
Hartnup disease is caused by mutations in the SLC6A19 gene. This gene provides instructions for making a protein called B0AT1, which is primarily found embedded in the membrane of intestine and kidney cells. The function of this protein is to transport certain amino acids into cells.
