Claim: USH2A gene encodes the protein Usherin that contains laminin EGF motifs; mutations within this gene have been associated with Usher syndrome type IIa (also known as Hallgren syndrome).
Evidence: This gene encodes the protein Usherin that contains laminin EGF motifs, a pentraxin domain, and many fibronectin type III motifs. Mutations within this gene have been associated with Usher syndrome type IIa. Usher–Hallgren syndrome
