Inborn Errors of Metabolism Portal

This portal is set up to give an overview of all Inherited Metabolic Disorders (IMDs, also known as Inborn Errors of Metabolism (IEM), see 2021 classification) pathways. This portal is also featured in the latest NAR Database Issue on WikiPathways.

IMPORTANT: the current list of pathways is originally based on the currently published (2014) 4th edition of the book (ISBN 3642403360 (978-3642403361)) and being updated for the new fifth edition (DOI 10.1007/978-3-030-67727-5 and ISBN:978-3-030-67726-8) in a collaboration with the chapter authors.

Information on Pathway Curation:

This Table provides an overview of which chapters have been covered by WikiPathways. Approved pathways are coloured blue; pathways which still need work (however are a part of the database) are coloured orange.


Tip:

Click on the arrows behind the Table headers to sort this table based on Chapter number (edition 4 and 5 available), title, WikiPathways reference and Curation Status.

Data Analysis

With the pathways from the Blau book (as well as with other pathways on WikiPathways), various data analysis approaches can be performed. You can find the relevant book chapter as Open Access regarding these data approaches here: Slenter, D.N., Kutmon, M., Willighagen, E.L. (2022). WikiPathways: Integrating Pathway Knowledge with Clinical Data. In: Blau, N., Dionisi Vici, C., Ferreira, C.R., Vianey-Saban, C., van Karnebeek, C.D.M. (eds) Physician's Guide to the Diagnosis, Treatment, and Follow-Up of Inherited Metabolic Diseases. Springer, Cham. DOI:10.1007/978-3-030-67727-5_73.
