Zusammenfassung: | The wide spectrum of clinical phenotypes associated with the
FMR1
premutation affect more than two million people worldwide. The clinical implications have only been recognized recently despite this disorder constitutes a relevant health problem. The present issue of
The Cerebellum
is focused on the “2
nd
International Conference on the
FMR1
Premutation: Basic Mechanisms and Clinical Involvement” held in Sitges, Barcelona (Spain), from September 30th to October 2nd, 2015. The conference was attended by professionals from different countries in Europe, the USA, Chile, Israel, Australia, and Indonesia and covered the latest clinical and molecular findings resulting from
FMR1
premutation studies. Although the pathologies associated with the
FMR1
premutation are considered as rare diseases, seventy abstracts were presented. This reflects the relevance of this topic in the medical community and the growing interest among professionals from other disciplines. The major topics discussed included why and how the mRNA toxicity due to a gain of function and non-canonical RAN are responsible for disorders associated with the premutation. Several presentations addressed the impact of these mechanisms in FXTAS and FXPOI, two clinical presentations caused by the
FMR1
premutation. Interestingly, a deterioration of the DNA repair machinery was first proposed as the pathogenicity cause of premutation alleles. Communications related to FXTAS and FXPOI animal models were also presented. These models facilitate studies aimed to understand disease progression and early treatment interventions. Finally, there were presentations related to psychiatric, psychological, neurological, and radiological aspects. Interesting discussion on intermediate alleles and their involvement in clinical and reproductive aspects was generated. In this regards, genetic counselling is improved by taking into account the AGG interruptions and including information about the
FMR1
premutation associated pathologies although there are still some uncertainties linked to the spectrum of these pathologies. Overall, the meeting covered all aspects of the different pathologies associated with the premutation of the
FMR1
gene. |
