Summaries for Usher Syndrome, Type 3a

About this section
UniProtKB/Swiss-Prot:70 Usher syndrome 3A: USH is a genetically heterogeneous condition characterized by the association of retinitis pigmentosa with sensorineural deafness. Age at onset and differences in auditory and vestibular function distinguish Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher syndrome type 3 (USH3). USH3 is characterized by postlingual, progressive hearing loss, variable vestibular dysfunction, and onset of retinitis pigmentosa symptoms, including nyctalopia, constriction of the visual fields, and loss of central visual acuity, usually by the second decade of life.

MalaCards based summary: Usher Syndrome, Type 3a, also known as usher syndrome type 3, is related to usher syndrome, type 2a and usher syndrome, type 2c, and has symptoms including sensorineural hearing impairment, visual impairment and abnormal electroretinogram. An important gene associated with Usher Syndrome, Type 3a is CLRN1 (Clarin 1), and among its related pathways is tRNA Aminoacylation. Affiliated tissues include eye and retina.

NIH Rare Diseases:48 Usher syndrome is a genetic condition characterized by hearing loss or deafness, and progressive vision loss due to retinitis pigmentosa. Three major types of Usher syndrome have been described - types I, II, and III.  The different types are distinguished by their severity and the age when signs and symptoms appear. All three types are inherited in an autosomal recessive manner, which means both copies of the disease-causing gene in each cell have mutations. Last updated: 3/3/2014
