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.Pro3504Ala in Exon 53 of USH2A: This variant has been reported as a `likely ne utral? variant in an Usher syndrome study based on either its presence in an aff ected individual who carried two other causative variants or because it did not segregate with disease (Le Quesne Stabej 2012). It was also identified in 1/878 (0.12%) control chromosomes by the same study (Le Quesne Stabej 2012), and in 1. 1% (348/30782) of South Asian chromosomes including 8 homozygotes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; rs200372118). Th e proline (Pro) residue at position 3504 is not conserved in several species mam mals, with rat and mouse having an alanine (Ala), and computational tools (amino acid biochemical properties, SIFT, PolyPhen-2, AlignGVGD) do not suggest an imp act to the protein. In summary, this variant is not expected to have clinical si gnificance based on the conservation and computational data, and its presence in the general population. -
