Brief Title

Clinical and Genetic Examination of Usher Syndrome Patients' Cohort in Europe

Official Title

European Research Projects on Rare Diseases Driven by Young Investigators

Brief Summary

      This study aims to characterize Usher patients in order to correlate this data with genetic
      information.

      Tasks:

        -  Standardization and improvement of Usher syndrome diagnosis: refine and elaborate
           special tests of visual and otological function in association with genotype that enable
           to determine the most significant markers for Usher disease progression and therapeutic
           effect.

        -  Perform genotype and phenotype correlations in Usher syndrome patients

        -  Develop and maintain database for phenotypically and genotypically well-characterized
           patient cohorts, suitable for future therapeutic trials
