Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000155111 SCV000204797 likely benign not specified 2013-03-14 criteria provided, single submitter clinical testing p.Asp3992Asn in exon 58 of GPR98: This variant is not expected to have clinical significance because it has been identified in 0.4% (59/15416) of European chrom osomes and in 0.4% (4/944) of Latino chromosomes by the Exome Aggregation Consor tium (http://exac.broadinstitute.org/; dbSNP rs201386977).
GeneDx RCV000155111 SCV000321754 uncertain significance not specified 2017-05-11 criteria provided, single submitter clinical testing The D3992N variant in the ADGRV1 gene has been reported previously in an individual with Usher syndrome who also harbored a nonsense variant in the ADGRV1 gene, although parental studies were not performed to determine the phase of these two variants (Bonnet et al., 2016). The D3992N variant has also been reported in individuals with features suggestive of Usher syndrome but without a second disease causing variant in the ADGRV1 gene identified (Licastro et al., 2012; Aparisi et al., 2014). The D3922N is observed in 59/15,416 (0.38%) alleles from individuals of non-Finnish European background in the ExAC dataset (Lek et al., 2016). Additionally, this variant has been observed in the homozygous state in two unrelated, presumably healthy individuals tested at GeneDx. The D3992N variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret D3992N as a variant of uncertain significance.

ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000585241 SCV000884985 uncertain significance not provided 2017-10-03 criteria provided, single submitter clinical testing The p.Asp3992Asn variant (rs201386977) has been reported in the medical literature in several individuals with Usher syndrome; however, inheritance and specific clinical information were not reported (Aparisi 2014, Bonnet 2016, and Licastro 2012). The p.Asp3992Asn variant is listed in the Genome Aggregation Database (gnomAD) browser with an overall allele frequency of 0.14% (identified in 313 out of 225,132 chromosomes), and found in ClinVar with conflicting interpretations of pathogenicity (Variant ID: 178365). The aspartic acid at codon 3992 is highly conserved considering 12 species up to zebrafish (Alamut software v2.10.0), and computational analyses suggest that this variant affects the structure/function of the ADGRV1 protein (SIFT: damaging, PolyPhen2: probably damaging, MutationTaster: disease causing). However, based on the available information, the clinical significance of the p.Asp3992Asn variant cannot be determined with certainty.

Illumina Clinical Services Laboratory,Illumina RCV001153109 SCV001314364 uncertain significance Usher syndrome, type 2C 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
