Whole genome sequencing (WGS) is increasingly recognized as a vital technique in (diagnostic) genetic screening of disease, including inherited retinal diseases (IRDs), such as USH2A-associated Usher syndrome type 2 (USH2, MIM: #276901) and autosomal recessive retinitis pigmentosa (arRP, MIM: #613809). Here, USH2A is linked to autosomal recessive retinitis pigmentosa.
