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.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -18 ACMG points.

PM1
In a domain Fibronectin type-III 27 (size 104) in uniprot entity USH2A_HUMAN there are 33 pathogenic changes around while only 13 benign (72%) in NM_206933.4
BP4
Computational evidence support a benign effect (MetaRNN=0.0027201176).
BP6
Variant 1-215675303-T-C is Benign according to our data. Variant chr1-215675303-T-C is described in ClinVar as [Benign]. Clinvar id is 48402.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-215675303-T-C is described in Lovd as [Benign].
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00198 (2889/1461774) while in subpopulation EAS AF= 0.0298 (1184/39696). AF 95% confidence interval is 0.0284. There are 46 homozygotes in gnomad4_exome. There are 1408 alleles in male gnomad4_exome subpopulation. Median coverage is 37. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 9 AR gene
