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.

Variant summary: USH2A c.9259-14A>C alters a non-conserved nucleotide located near a canonical splice site and therefore could affect mRNA splicing. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00075 in 251180 control chromosomes in the gnomAD database, including 1 homozygote. This frequency is not significantly higher than estimated for a pathogenic variant in USH2A causing Usher Syndrome (0.00075 vs 0.011), however the presence of a homozygous individual is supportive of the benign nature of the variant. To our knowledge, no occurrence of c.9259-14A>C in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -

c.9259-14A>C in intron 46 of USH2A: This variant is not expected to have clinica l significance because it has been identified in 0.7% (109/16498) of South Asia n chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstit ute.org; dbSNP rs561590242), and a cytosine "C" at this position does not diverg e from the 3' splice site consensus sequence. -
