Comments:  Usher syndrome type II is a genetically heterogeneous autosomal recessive disorder characterised by hearing loss and retinitis pigmentosa. Several different mutations have been in single families. Another mutation has been found in a family with familial febrile seizures. Usher syndrome type IIC can also be caused by biallelic digenic mutation in PDZD7 and GPR98.
