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 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.4129105).

Variant classified as Uncertain Significance - Favor Pathogenic. The Lys2484Asn variant in GPR98 has not been reported in the literature nor previously identifi ed by our laboratory. Computational analyses (biochemical amino acid properties, conservation, PolyPhen2, and SIFT) suggest that the Lys2484Asn variant may impa ct the protein, though this information is not predictive enough to determine pa thogenicity. In summary, additional information is needed to determine the clini cal significance of this variant; however, based upon the computational predicti on data, we would lean towards a more likely pathogenic role. -
