Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP4_StrongBP6_Very_StrongBS2_Supporting

The NM_206933.4(USH2A):c.6001C>T(p.Arg2001Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000178 in 1,613,980 control chromosomes in the GnomAD database, including 4 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2001G) has been classified as Uncertain significance.

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 -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0056596696).

BP6

Variant 1-216070149-G-A is Benign according to our data. Variant chr1-216070149-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 517292.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-216070149-G-A is described in Lovd as [Likely_pathogenic]. Variant chr1-216070149-G-A is described in Lovd as [Benign].

BS2

High Homozygotes in GnomAdExome4 at 3 AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

p.Arg2001Cys in exon 30 of USH2A: This variant is not expected to have clinical significance because it has been identified in 0.5% (47/8630) of East Asian chro mosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.or g; dbSNP rs141539554). In addition, this amino acid position is not highly conse rved in mammals including three mammals (shrew, star-nosed mole, and elephant) w ith a Cysteine (C) at this position. -
