1. 1. Usher syndrome. Prevalence and phenotype - genotype correlations

   Författare :Mehdi Sadeghi; Göteborgs universitet; []
   Nyckelord :deafblindness; Usher syndrome; retinitis pigmentosa; prevalence; Usher type I; Usher type II; Usher type III; vestibular deficiency; hereditary hearing loss;

   Sammanfattning : Aims: the main purpose of this thesis was to estimate the prevalence of Usher syndrome type I, II and III in Sweden (study I) and to determine the clinical differences between Usher syndrome subtypes (studies II-IV). The hypothesis to be tested was that different genes for Usher syndrome will produce different phenotypes even when they belong to the same clinical type (studies II and III). LÄS MER
