p.Ile675Leu in exon 11 of GPR98: This variant is not expected to have clinical s ignificance because it has been identified in 0.4% (35/8602) of African chromoso mes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; d bSNP rs200187681}.
Variant summary: ADGRV1 c.2023A>C (p.Ile675Leu) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0002 in 1605308 control chromosomes, predominantly at a frequency of 0.0036 within the African or African-American subpopulation in the gnomAD database, including 2 homozygotes strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. To our knowledge, no occurrence of c.2023A>C in individuals affected with ADGRV1-Related Disorders and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 227402). Based on the evidence outlined above, the variant was classified as likely benign.
ADGRV1-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications).
