Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_206933.4(USH2A):c.7452G>T(p.Glu2484Asp) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000274 in 1,461,078 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/26 in silico tools predict a benign outcome for this variant. 2/3 splice prediction tools predict no significant impact on normal splicing. 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. E2484K) has been classified as Uncertain significance.

Submissions by phenotype
not specified Uncertain:1
The Glu2484Asp variant in USH2A has not been reported in the literature nor prev iously identified by our laboratory. Computational analyses (biochemical amino a cid properties, homology, PolyPhen2, SIFT, AlignGVGD) do not provide strong supp ort for or against pathogenicity. Although this variant also occurs within the s plice consensus sequence, it does not predict a significant enough impact to the splice sequence to assume it is pathogenic. In summary, the clinical significan ce of this variant cannot be determined with certainty at this time. -
