Are there prenatal tests for maple syrup urine disease?
Maple Syrup Urine Disease is inherited as an autosomal recessive disease. Parents of a child with MSUD are assumed to be carriers for the disorder and have a 1 in 4 (25%) chance, in each pregnancy, of having another child with this condition. Prenatal testing for MSUD can be done as early as 10-12 weeks of pregnancy.
What sort of enzyme deficiency is responsible for maple syrup urine disease?
Maple syrup urine disease (MSUD) is a rare genetic disorder characterized by deficiency of an enzyme complex (branched-chain alpha-keto acid dehydrogenase) that is required to break down (metabolize) the three branched-chain amino acids (BCAAs) leucine, isoleucine and valine, in the body.
What kind of doctor treats maple syrup urine disease?
The mainstay in the treatment of maple syrup urine disease is dietary restriction of branched-chain amino acids (BCAAs). Consultation with a neonatal/pediatric nutritionist with expertise in dietary management of metabolic disorders is required to address medical nutrition therapy immediately.
What tests are done to diagnose maple syrup urine disease?
Diagnosis and Tests In these cases, doctors diagnose MSUD with blood tests and by evaluating the child’s symptoms, including finding the distinctive sugar/maple smell of their sweat and urine. Genetic testing from white cells in blood can now help confirm diagnosis and also help identify types of MSUD.
Why does my daughter smell like maple syrup?
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.
What disease makes you smell like maple syrup?
Maple syrup urine disease (MSUD) is a disorder in which the body cannot break down certain parts of proteins. The urine of people with this condition can smell like maple syrup.
Do diabetics smell like syrup?

What disease smells like maple syrup?
How does a person get diagnosed with MSUD?
MSUD is caused by genetic variants in the BCKDHA, BCKDHB, or DBT genes. It is inherited in an autosomal recessive pattern. Diagnosis of MSUD is based on the symptoms, clinical exam, and blood and urine testing. MSUD is often diagnosed based on the results of a newborn screening test.
How does tandem mass spectrometry help diagnose MSUD?
Tandem mass spectrometry, an advanced newborn screening test that screens for more than 30 different disorders through one blood sample, has aided in the diagnosis of MSUD. Infants with mild or intermittent forms of the disorder may have totally normal blood amino acids after birth and thus can be missed by newborn screening.
How is maple syrup urine disease ( MSUD ) diagnosed?
Listen Maple syrup urine disease (MSUD) is often diagnosed based on the results of a newborn screening test. The diagnosis is then confirmed by urine and blood testing. In some cases, especially in adolescents and adults, MSUD is diagnosed based on the symptoms, clinical exam, and the results of urine and blood testing.
How does MSUD build up in the brain?
This leads to a buildup of these chemicals in the blood. In the most severe form, MSUD can damage the brain during times of physical stress (such as infection, fever, or not eating for a long time). Some types of MSUD are mild or come and go.
