NCT02455414

Brief Summary

The goal of this study is to determine the pattern of early neurodegenerative changes in WFS (Wolfram Syndrome). The investigator will perform cross-sectional and longitudinal assessments of youth with WFS, targeting sensitive neural systems with quantified neuroimaging and behavioral measures. In addition, the investigator will establish the utility of a WFS severity rating scale (WFS Unified Rating Scale or WURS). Preliminary data support the feasibility of this approach and its potential to generate important new information about neurodevelopmental and neurodegenerative patterns in WFS. This work is necessary to position the field for future clinical trials to test interventions for WFS neurodegeneration. Ultimately, a better understanding of the trajectory of neurodegeneration in WFS and the development of effective interventions may be relevant to other more common neurodegenerative and endocrine (Type 1 and Type 2 diabetes) diseases in which ER stress has been implicated.

Biospecimen

Retention: SAMPLES WITH DNA

A skin biopsy will be obtained from which the investigator will sequence all the exons and exon-intron junctions of the WFS1 gene. In some cases, the investigator will also sequence other genes related to Wolfram syndrome including WFS2, MANF, and Caspase-12. If the investigator doesn't find mutations in these genes, a whole-exome sequencing may be performed. The genetic test provided has the potential to create a uniquely-identifiable fingerprint that could possibly identify a participant.
