Genes affected

RSPO2 (HGNC:28583): (R-spondin 2) This gene encodes a member of the R-spondin family of proteins. These proteins are secreted ligands of leucine-rich repeat containing G protein-coupled receptors that enhance Wnt signaling through the inhibition of ubiquitin E3 ligases. A chromosomal translocation including this locus that results in the formation of a gene fusion has been identified in multiple human cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

The c.697A>G (p.S233G) alteration is located in exon 6 (coding exon 5) of the RSPO2 gene. This alteration results from a A to G substitution at nucleotide position 697, causing the serine (S) at amino acid position 233 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
