Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PVS1 PM2 PP5_Moderate

The NM_032119.4(ADGRV1):​c.11253C>G​(p.Tyr3751*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. Y3751Y) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Genes affected

ADGRV1 (HGNC:17416): (adhesion G protein-coupled receptor V1) This gene encodes a member of the G-protein coupled receptor superfamily. The encoded protein contains a 7-transmembrane receptor domain, binds calcium and is expressed in the central nervous system. Mutations in this gene are associated with Usher syndrome 2 and familial febrile seizures. Several alternatively spliced transcripts have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-90753705-C-G is Pathogenic according to our data. Variant chr5-90753705-C-G is described in ClinVar as Pathogenic. ClinVar VariationId is 46254.Status of the report is criteria_provided_single_submitter, 1 stars.

The Tyr3751X variant in GPR98 has not been reported in the literature nor previo usly identified by our laboratory. This nonsense variant leads to a premature te rmination codon at position 3751, which is predicted to lead to a truncated or a bsent protein. In summary, this variant meets our criteria to be classified as p athogenic (http://pcpgm.partners.org/LMM). -
