3-meth·yl·glu·ta·con·ic ac·i·du·ri·a

(meth'il-glū'tă-kon'ik as'i-dyū'rē-a),
Elevated levels of 3-methylglutaconic acid in the urine. An inherited disorder the mild form of which is a result of a deficiency of 3-methylglutaconyl-CoA hydratase, leading to delayed speech development.

Enzyme defects indicated by solid bars are numbered as follows: (1), branched-chain 2-ketoacid dehydrogenase complex deficiency (MSUD, maple syrup urine disease); (2), isovaleryl-CoA dehydrogenase deficiency (isovaleric acidemia); (3), isolated 3-methylcrotonyl-CoA carboxylase deficiency; (4), 3-methylcrotonyl-CoA carboxylase deficiency as part of a multiple carboxylase deficiency due to nutritional biotin deficiency or biotinidase deficiency or holocarboxylase synthetase deficiency or carbonic anhydrase VA deficiency or MT-ATP6 deficiency; (5), 3-methylglutaconyl-CoA hydratase deficiency; (6), 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) lyase deficiency.
C50H is increased in 3-methylcrotonyl-CoA carboxylase deficiency, 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, and 3-methylglutaconyl-CoA hydratase deficiency, whereas 2-methyl-3-hydroxybutyrylcarnitine is increased in [beta]-ketothiolase deficiency and 2-methyl-3-hydroxybutyrl-CoA dehydrogenase deficiency (118).
