Genetic disorders of cellular trafficking

Cellular trafficking is essential to maintain critical biological functions. Mutations in 346 genes, most of them described in the last 5 years, are associated with disorders of cellular trafficking. Whereas initially restricted to membrane trafficking, the recent detection of many diseases has contributed to the discovery of new biological pathways. Accordingly, we propose to redesign this rapidly growing group of diseases combining biological mechanisms and clinical presentation into the following categories: (i) membrane trafficking (including organelleWe present the most recently described pathophysiological findings, disorders and phenotypes. Although all tissues and organs are affected, the nervous system is especially vulnerable.

Automated summary

Cellular trafficking is crucial for maintaining biological functions, and mutations in 346 genes have been found to be associated with disorders in this process. The recent detection of many diseases has led to the discovery of new biological pathways.
