Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_032119.4(ADGRV1):c.670G>A(p.Glu224Lys) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000005 in 1,599,942 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/23 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

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]

Collection Method:clinical testing

The Glu224Lys variant in GPR98 has not been previously reported in individuals w ith hearing loss or in large population studies. This variant is located in the last three bases of the exon, which is part of the 3? splice region. Computation al tools do not suggest an impact to splicing. However, this information is not predictive enough to rule out pathogenicity. Computational prediction tools and conservation analyses do not provide strong support for or against an impact of the amino acid change to the protein. In summary, additional information is need ed to fully assess the clinical significance of this variant. -
