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 Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 5-90694707-C-T is Benign according to our data. Variant chr5-90694707-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 46382.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr5-90694707-C-T is described in Lovd as [Likely_benign]. Variant chr5-90694707-C-T is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0101 (1539/152156) while in subpopulation AFR AF= 0.0351 (1458/41508). AF 95% confidence interval is 0.0336. There are 30 homozygotes in gnomad4. There are 750 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 30 AR,Digenic gene

Apr 27, 2017

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
