RCV000483825 | SCV000573128 | uncertain significance | not provided | 2017-02-23 | criteria provided, single submitter | clinical testing | The A477V variant in the ADAMTS2 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The A477V variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The A477V variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret A477V as a variant of uncertain significance. |

RCV001233233 | SCV001405816 | uncertain significance | Ehlers-Danlos syndrome, dermatosparaxis type | 2022-06-27 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 477 of the ADAMTS2 protein (p.Ala477Val). This variant is present in population databases (rs370614125, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with ADAMTS2-related conditions. ClinVar contains an entry for this variant (Variation ID: 423427). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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 | RCV004023193 | SCV004852411 | uncertain significance | Inborn genetic diseases | 2023-12-18 | criteria provided, single submitter | clinical testing | The c.1430C>T (p.A477V) alteration is located in exon 9 (coding exon 9) of the ADAMTS2 gene. This alteration results from a C to T substitution at nucleotide position 1430, causing the alanine (A) at amino acid position 477 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
