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.

Genetics and Pathophysiology of Premature Aging
Progeria, the phenomenon of premature aging, is an ultra-rare genetic condition. A recent study reported mutations in MTX2 as the cause of a novel progeroid syndrome and revealed mitochondrial dysfunction as contributing to the pathophysiology in progeria. The study, which utilized CENTOGNE’s…

A Variant-Specific Mutational Effect
A given genetic disorder is usually associated with numerous distinct mutations in the underlying gene. For a novel neurodegenerative syndrome, however, only a single TRAPPC4 variant seems to be causative. A cohort of 23 pertinent patients, many of which were identified at CENTOGENE, was published…

Large Patient Cohort Enables Insights into a Rare Disease
Farber disease (FD) is a severe disorder for which rarity has hampered a comprehensive understanding. A recent study on a large cohort of patients provides unprecedented novel insights into FD. The study, to which CENTOGENE contributed genetic as well as biomarker data, was published in Clinical…

Unlocking the Genetics of Seizures
Seizures are frequently rooted in a genetic factor, but many of the corresponding disorders are ultra-rare. A new study reports ADARB1 mutations in two families in which patients suffer from a severe seizure+ syndrome; one of these families was identified at CENTOGENE. The study, which confirms…

A Novel Disorder of Nerve Cell Communication
Proper development and function of nerve cells relies on communication by so-called neurotransmitters. Mutations in the GAD1 gene, which is involved in neurotransmitter synthesis, have now been found to cause a multitude of severe neurological phenotypes.
