Genes affected

USH2A (HGNC:12601): (usherin) This gene encodes a protein that contains laminin EGF motifs, a pentaxin domain, and many fibronectin type III motifs. The protein is found in the basement membrane, and may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIa and retinitis pigmentosa. Multiple transcript variants encoding different isoforms have been found for this gene.

p.Asn3742Ser in exon 57 of USH2A: This variant is not expected to have clinical significance because it has been identified in 0.21% (50/24030) of African chrom osomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute. org/; dbSNP rs139921272). In addition, computational prediction tools do not sug gest a high likelihood of impact to the protein. ACMG/AMP Criteria applied: BS1_ Supporting; BP4. -
