Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_178565.5(RSPO2):ā€‹c.697A>Gā€‹(p.Ser233Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000558 in 1,614,180 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S233I) has been classified as Uncertain significance.

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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 08, 2022The 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. -
