branched chain ketoaciduria
Noun: - An inherited metabolic disorder: A genetic condition where the body cannot properly break down certain amino acids (the building blocks of proteins), specifically the branched-chain amino acids leucine, isoleucine, and valine. This leads to a harmful buildup of these substances and their byproducts in the body. - Characterized by maple syrup odor: A key symptom is urine, earwax, and sweat that have a distinctive sweet smell, often compared to maple syrup or burnt sugar. - A serious health condition: If not diagnosed and treated immediately after birth, the accumulation of toxins causes severe neurological damage, leading to symptoms such as poor feeding, vomiting, lethargy, seizures, developmental delays, mental retardation, coma, and can be fatal.
- Noun:
- Newborn screening tests are crucial for the early detection of branched chain ketoaciduria.
- The doctor explained that branched chain ketoaciduria requires a strict lifelong diet.
- Management of branched chain ketoaciduria involves a special formula low in the problematic amino acids.
- Medical abbreviation: The condition is very commonly referred to by its abbreviation, MSUD (Maple Syrup Urine Disease). In medical literature, you will often see "MSUD" used interchangeably with the full term.
- The research paper focused on new treatment strategies for MSUD.
- Clinical context: The term is used to specify the biochemical nature of the disease (involving branched-chain ketoacids) as opposed to other metabolic disorders.
- The differential diagnosis included branched chain ketoaciduria and other organic acidemias.
- Maple Syrup Urine Disease (MSUD) (n): The most common name for the condition, directly describing the hallmark symptom.
- Branched-chain alpha-keto acid dehydrogenase deficiency (n): The precise biochemical name describing the specific enzyme that is deficient in this disorder.
- Metabolic disorder (n): The general category of diseases to which branched chain ketoaciduria belongs.
- Inborn error of metabolism (n): A broader term for genetic conditions involving metabolic pathway defects.
- Maple Syrup Urine Disease (MSUD): The primary synonym.
- BCKD deficiency: An abbreviation derived from the enzyme name (Branched-chain alpha-keto acid dehydrogenase).
- To be diagnosed with branched chain ketoaciduria: To be formally identified as having the condition.
- The infant was diagnosed with branched chain ketoaciduria through a heel-prick test.
- To manage/treat branched chain ketoaciduria: To control the condition through dietary and medical intervention.
- The family learned how to manage branched chain ketoaciduria with the help of a dietitian.
-
an inherited disorder of metabolism in which the urine has a odor characteristic of maple syrup; if untreated it can lead to mental retardation and death in early childhood
