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

Classification was made for transcript

Our verdict: Pathogenic. The variant received 16 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 6.4, offset of 5, new splice context is: taatttttttcccggatcAGgtt. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

PP5

Variant 5-90810231-A-G is Pathogenic according to our data. Variant chr5-90810231-A-G is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 46275.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
