Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_206933.4(USH2A):c.6874C>T(p.Arg2292Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000479 in 1,461,436 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2292H) has been classified as Benign.

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 classified as Uncertain Significance - Favor Benign. The Arg2292Cys vari ant in USH2A has not been previously reported in individuals with hearing loss a nd was absent from large population studies. The arginine (Arg) at position 2292 is not conserved in mammals or evolutionary distant species, raising the possib ility that a change at this position may be tolerated. Additional computational prediction tools suggest that the Arg2292Cys variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the Arg2292Cys variant is uncertain, these data suggest that is more likely to be benign. -
