This sequence change creates a premature translational stop signal (p.Arg800*) in the ADGRV1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ADGRV1 are known to be pathogenic (PMID: 19357117, 22135276, 22147658, 26226137, 30718709, 31047384, 32467589). This variant is present in population databases (rs373780305, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with Usher syndrome (PMID: 22135276). ClinVar contains an entry for this variant (Variation ID: 46306). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss of function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 31964843, 31589614, 36357925, 22135276) -

The Arg800X variant in GPR98 has been reported in one individual with Usher synd rome who had a second GPR98 variant (Le Quesne Stabej 2012). This nonsense varia nt leads to a premature termination codon at position 800, which is predicted to lead to a truncated or absent protein. In summary, this variant meets our crite ria to be classified as pathogenic (http://pcpgm.partners.org/LMM). -
