Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000614895	SCV000712805	uncertain significance	not specified	2016-12-13	criteria provided, single submitter	clinical testing	The p.Ser3590Cys variant in GPR98 has been previously reported in 1 individual w ith type 1 Usher syndrome explained by a homozygous variant in another gene (Bon net 2016). The p.Ser3590Cys variant has been reported in 0.1% (36/31300) of Lat ino chromosomes by the Genome Aggregation Consortium (gnomAD, http://gnomad.broa dinstitute.org; dbSNP rs183319660). Computational prediction tools and conserva tion analyses suggest that this variant may impact the protein, though this info rmation is not predictive enough to determine pathogenicity. Furthermore, this variant is located in the last three bases of the exon, which is part of the 5' splice region. Computational tools do not suggest an impact to splicing. However , this information is not predictive enough to rule out pathogenicity. In summar y, the clinical significance of the p.Ser3590Cys variant is uncertain.
Labcorp Genetics (formerly Invitae), Labcorp	RCV001245971	SCV001419298	uncertain significance	not provided	2025-01-23	criteria provided, single submitter	clinical testing	This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 3590 of the ADGRV1 protein (p.Ser3590Cys). This variant is present in population databases (rs183319660, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with ADGRV1-related conditions. ClinVar contains an entry for this variant (Variation ID: 505525). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus 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.
ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	RCV001245971	SCV001473235	uncertain significance	not provided	2020-05-28	criteria provided, single submitter	clinical testing	The ADGRV1 c.10768A>T; p.Ser3590Cys variant (rs183319660) is reported in the literature in an individual affected with Usher syndrome who also carried a homozygous MYO7A variant (Bonnet 2016). This variant is reported in ClinVar (Variation ID: 505525), and is found in the Latino population with an allele frequency of 0.12% (38/30556 alleles, including a single homozygote) in the Genome Aggregation Database. The serine at codon 3590 is moderately conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Other computational analyses (Alamut v.2.11) predict that this variant may impact splicing by weakening the nearby canonical donor splice site, however without functional studies, the effect on splicing is unknown. Due to limited information, the clinical significance of the p.Ser3590Cys variant is uncertain at this time. References: Bonnet et al.
