Most of the disease-causing mutations that science has been able to identify so far are located within the exons. Whereas most genetic tests focus on a single gene or on a set number of predetermined genes, whole exome sequencing examines thousands of genes simultaneously.

An Unorthodox Disease Mechanism
Essential proteins are defined as those that are necessary for living. In theory, homozygous loss-of-function variants that only affect certain isoforms may still be found in living individuals. A recent study involving patients that were identified at CENTOGENE presents one of the first examples of…

Disease relevance of alternative splicing
Alternative splicing of genes usually generates several isoforms. These may code for slightly differing proteins, the disease relevance of which is often not clear. Researchers from CENTOGENE, by reporting a representative example, emphasized the resulting challenges in a recent study. They…

Novel Insights into a Rare Disorder
A profound understanding of rare genetic disorders relies on the description of large numbers of patients. Based on its unique positioning in the rare disease field, CENTOGENE can significantly contribute on multiple levels. This is exemplified by a recent corresponding study in the Journal of…

Novel Genetic Cause for Neurodevelopmental Defects
Many proteins are crucial for proper brain development. By showing that certain neurodevelopmental defects are associated with mutations in TMX2, this study adds an enzyme of the redox signaling pathway to the list of vital proteins. These findings, which were partially based on data generated at…

Disturbed lipid metabolism causes congenital disease
Lipid metabolism is crucially involved in embryonic development, and recent research uncovered yet another link. Genetic screening revealed that inactivation of the enzyme sphingomyealinase-3 results in prenatal abnormalities, and in vitro studies defined the underlying pathophysiology. The study,…
