Isovaleric acidemia synonyms

Isovaleric acidemia, also known as isovaleric aciduria, is a rare metabolic disorder caused by a deficiency of the enzyme isovaleryl-CoA dehydrogenase. While it is most frequently referred to by these two terms, it is also historically known as "sweaty feet syndrome" due to the distinct odor of its metabolic byproduct, isovaleric acid.

What are the common synonyms for Isovaleric acidemia?

In medical literature and clinical documentation, Isovaleric acidemia is primarily identified by its biochemical nature. The most common synonyms and abbreviations you may encounter in your medical records include:

• Isovaleric aciduria (the most frequent alternative)


• IVA (the standard clinical abbreviation)


• Isovaleryl-CoA dehydrogenase deficiency (the specific enzymatic cause)


• Sweaty feet syndrome (a colloquial term derived from the characteristic body odor associated with the buildup of isovaleric acid)


• Hyperleucinemia (an older, less specific term referring to the elevation of leucine levels)

Why are there multiple names for this condition?

The variety of names for Isovaleric acidemia stems from the evolution of medical diagnostics. Early in the study of metabolic diseases, conditions were often named after their most prominent clinical feature—in this case, the unique, pungent odor of sweat resembling sweaty feet. As clinical genetics advanced, researchers identified the specific enzyme deficiency, leading to the more precise term "isovaleryl-CoA dehydrogenase deficiency." Today, Isovaleric acidemia is the preferred clinical term because it describes the primary physiological manifestation (the presence of isovaleric acid in the blood) while remaining concise for electronic health records.

How is Isovaleric acidemia classified in medical systems?

Standardized medical classification systems provide consistency for researchers and clinicians worldwide. If you are searching for Isovaleric acidemia in official databases, use these identifiers:

1. Orphanet: Listed as ORPHA:448, categorized as a rare inborn error of metabolism.


2. OMIM (Online Mendelian Inheritance in Man): Referenced under the entry #243500.


3. ICD-10-CM: Classified under code E71.110 (Isovaleric acidemia).


4. ICD-11: Classified under code 5C50.00.

Why is it important to know these synonyms?

For the 23 community members at DiseaseMaps.org and families managing Isovaleric acidemia, understanding these synonyms is vital for several reasons. Medical records may use "IVA" or "Isovaleric aciduria" interchangeably, and older literature may still refer to the condition as "sweaty feet syndrome." Being familiar with these terms ensures that when you communicate with specialists, pharmacists, or emergency room staff, you can confirm you are discussing the same diagnosis. Furthermore, when conducting independent research on sites like PubMed or NIH GARD, searching for both Isovaleric acidemia and "isovaleryl-CoA dehydrogenase deficiency" will yield the most comprehensive results.

Next steps
