GeneDx RCV000599234 SCV000709808 pathogenic not provided 2018-03-05 criteria provided, single submitter clinical testing The c.17668_17669delAT variant has been published previously in association with Usher syndrome (Bonnet et al., 2011). The variant is observed in 2/15244 (0.013%) alleles from individuals of African background in large population cohorts (Lek et al., 2016). The variant causes a frameshift starting with codon Methionine 5890, changes this amino acid to a Valine residue and creates a premature Stop codon at position 10 of the new reading frame, denoted p.Met5890ValfsX10. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. In summary, we consider this variant to be pathogenic.

Invitae RCV000599234 SCV001380629 pathogenic not provided 2019-10-22 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Met5890Valfs*10) in the ADGRV1 gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs757696771, ExAC 0.01%). This variant has been observed in an individual affected with Usher syndrome (PMID: 21569298). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Loss-of-function variants in ADGRV1 are known to be pathogenic (PMID: 19357117, 22135276, 22147658). For these reasons, this variant has been classified as Pathogenic.
