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 Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07799092).
• BP6: Variant 5-90625211-G-A is Benign according to our data. Variant chr5-90625211-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 227410.Status of the report is criteria_provided_single_submitter, 1 stars.

p.Val214Ile in exon 6 of GPR98: This variant is not expected to have clinical si gnificance due to a lack of conservation across species, including mammals. Of n ote, 4 mammals (rat, hedgehog, elephant and aardvark) have an isoleucine (Ile) a t this position despite high nearby amino acid conservation. In addition, comput ational prediction tools do not suggest a high likelihood of impact to the prote in. -
