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 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.17500812).

The Ala1365Asp variant in GPR98 has not been reported in the literature nor prev iously identified by our laboratory. Computational analyses (biochemical amino a cid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide str ong support for or against an impact to the protein. In summary, the clinical si gnificance of this variant cannot be determined with certainty. -
