Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_032119.4(ADGRV1):c.9034A>G(p.Thr3012Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000015 in 1,602,998 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T3012I) has been classified 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]

Variant classified as Uncertain Significance - Favor Benign. The p.Thr3012Ala va riant in GPR98 has not been previously reported in individuals with hearing loss , but has been identified in 1/66294 European chromosomes by the Exome Aggregati on Consortium (ExAC, http://exac.broadinstitute.org). Although this variant has been seen in the general population, its frequency is not high enough to rule ou t a pathogenic role. The threonine (Thr) at position 3012 is not conserved thro ugh species, with 1 mammal (tenrec) having an alanine (Ala) at this position, su ggesting that variants at this position may be tolerated. Additional computation al prediction tools do not provide strong evidence for or against an impact to t he protein. In summary, while the clinical significance of the p.Thr3012Ala vari ant is uncertain, the lack of evolutionary conservation suggests that it is more likely to be benign. -

This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 3012 of the ADGRV1 protein (p.Thr3012Ala). This variant is present in population databases (rs764873763, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with ADGRV1-related conditions. ClinVar contains an entry for this variant (Variation ID: 228728). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
