RCV000041803 | SCV000065499 | uncertain significance | not specified | 2012-05-23 | criteria provided, single submitter | clinical testing | Variant classified as Uncertain Significance - Favor Benign. The Ser652Gly varia nt in USH2A has not been reported in the literature nor previously identified by our laboratory. Computational analyses (biochemical amino acid properties, cons ervation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Ser652Gly variant is not likely to impact the protein, primarily based upon a lack of conservation of the Ser652 amino acid position in other mammals; however, this information is n ot predictive enough to rule out pathogenicity. In summary, the clinical signifi cance of this variant cannot be determined with certainty; however, we would lea n towards a more likely benign role. |

RCV001307495 | SCV001496911 | uncertain significance | not provided | 2022-05-13 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 652 of the USH2A protein (p.Ser652Gly). This variant is present in population databases (rs397518005, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with USH2A-related conditions. ClinVar contains an entry for this variant (Variation ID: 48480). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glycine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |

Ambry Genetics | RCV004686574 | SCV005181348 | uncertain significance | Inborn genetic diseases | 2024-03-18 | criteria provided, single submitter | clinical testing | The c.1954A>G (p.S652G) alteration is located in exon 11 (coding exon 10) of the USH2A gene. This alteration results from a A to G substitution at nucleotide position 1954, causing the serine (S) at amino acid position 652 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
