Genes affected

ADGRB3 (HGNC:945): (adhesion G protein-coupled receptor B3) This p53-target gene encodes a brain-specific angiogenesis inhibitor, a seven-span transmembrane protein, and is thought to be a member of the secretin receptor family. Brain-specific angiogenesis proteins BAI2 and BAI3 are similar to BAI1 in structure, have similar tissue specificities, and may also play a role in angiogenesis. [provided by RefSeq, Jul 2008]

The c.632C>G (p.S211W) alteration is located in exon 3 (coding exon 1) of the ADGRB3 gene. This alteration results from a C to G substitution at nucleotide position 632, causing the serine (S) at amino acid position 211 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
