Description

This pathway shows an simplified version of the Krebs cycle (for more details see [1] ), with 4 genetic diseases related to it.

For succinyl-CoA synthetase deficiencies, relevant metabolic markers are depicted in light green. Patients with a mutation in the SUCLG1 might present a severe (fatal) form of mitochondrial encephalomyopathy.

This pathway was inspired by Chapter 20 of the book of Blau (ISBN 3642403360 (978-3642403361)).
