Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_032119.4(ADGRV1):c.13765G>A(p.Val4589Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,613,740 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V4589L) has been classified as Uncertain significance.

Submissions by phenotype
not provided    Uncertain:3 
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is uninformative in assessment of its pathogenicity (http://gnomad.broadinstitute.org). Computational tools predict that this variant is not damaging. -
This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 4589 of the ADGRV1 protein (p.Val4589Met). This variant is not present in population databases (gnomAD no frequency). 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: 163616). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
Inborn genetic diseases    Uncertain:1 
The c.13765G>A (p.V4589M) alteration is located in exon 68 (coding exon 68) of the ADGRV1 gene. This alteration results from a G to A substitution at nucleotide position 13765, causing the valine (V) at amino acid position 4589 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not specified    Benign:1 
Val4589Met in exon 68 of GPR98: This variant is not expected to have clinical si gnificance because the valine (Val) residue at position 4589 is poorly conserve d across species, with several species (pig, cow, and hedgehog) having a methion ine (Met) at this position. In addition, computational tools predict that the va riant may not impact the protein. -
