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

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.827

The p.Asp4571Gly variant in GPR98 has not been previously reported in individual s with hearing loss or in large population studies. Computational prediction too ls and conservation analyses suggest that the p.Asp4571Gly variant may impact th e protein, though this information is not predictive enough to determine pathoge nicity. In summary, the clinical significance of the p.Asp4571Gly variant is unc ertain. -
