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. [provided by RefSeq, Dec 2008]

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 9 uncertain in NM_206933.4

BP4

Computational evidence support a benign effect (MetaRNN=0.005207777).

BP6

Variant 1-215782771-C-T is Benign according to our data. Variant chr1-215782771-C-T is described in ClinVar as Benign. ClinVar VariationId is 48351.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00636 (968/152254) while in subpopulation AFR AF = 0.0218 (907/41558). AF 95% confidence interval is 0.0206. There are 8 homozygotes in GnomAd4. There are 438 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 8 AD,AR gene
