Genetic Variant ADGRB2:p.Pro1577Arg (chr1-31727448-G-C) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001364857.2(ADGRB2):c.4730C>G(p.Pro1577Arg) variant causes a missense change. The variant allele was found at a frequency of 0.000000696 in 1,435,794 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P1577L) has been classified as Benign.

Genes affected

ADGRB2 (HGNC:944): (adhesion G protein-coupled receptor B2) This gene encodes a a seven-span transmembrane protein that is thought to be a member of the secretin receptor family. The encoded protein is a brain-specific inhibitor of angiogenesis. The mature peptide may be further cleaved into additional products (PMID:20367554). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]
