Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 2P and 3B. PM2BP4_ModerateBP6
The NM_032119.4(ADGRV1):c.13714A>T(p.Ile4572Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000124 in 1,613,578 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 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. I4572V) has been classified as Uncertain significance.

not provided Uncertain:1
This sequence change replaces isoleucine with phenylalanine at codon 4572 of the ADGRV1 protein (p.Ile4572Phe). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and phenylalanine. This variant is present in population databases (rs727503082, ExAC 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: 163615). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The phenylalanine 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. -
not specified Benign:1
Ile4572Phe in exon 68 of GPR98: This variant is not expected to have clinical si gnificance due to a lack of conservation across species, including mammals. Of n ote, mouse, rat, kangaroo rat, guinea pig and other distance species have a phen ylalanine at this position despite high nearby amino acid conservation. In addit ion, computational analyses (PolyPhen2, SIFT, AlignGVGD) do not suggest a high l ikelihood of impact to the protein. -
