About this section
OMIM:52 Usher syndrome is a clinically and genetically heterogeneous autosomal recessive disorder characterized by... (605472) more...

MalaCards based summary: Usher Syndrome, Type 2c, also known as USH2C, is related to usher syndrome, type 2a and robinow syndrome, autosomal dominant 1, and has symptoms including rod-cone dystrophy and congenital sensorineural hearing impairment. An important gene associated with Usher Syndrome, Type 2c is ADGRV1 (Adhesion G Protein-Coupled Receptor V1). Related mouse phenotypes are behavior/neurological and cellular.

Disease Ontology:11 An Usher syndrome type 2 that has material basis in homozygous or compound heterozygous mutation in the ADGRV1 gene on chromosome 5q14.

UniProtKB/Swiss-Prot:70 Usher syndrome 2C: 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). USH2 is characterized by congenital mild hearing impairment with normal vestibular responses.
