Genes affected

RSPO1 (HGNC:21679): (R-spondin 1) This gene encodes a secreted activator protein with two cysteine-rich, furin-like domains and one thrombospondin type 1 domain. The encoded protein is a ligand for leucine-rich repeat-containing G-protein coupled receptors (LGR proteins) and positively regulates the Wnt signaling pathway. In mice, the protein induces the rapid onset of crypt cell proliferation and increases intestinal epithelial healing, providing a protective effect against chemotherapy-induced adverse effects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2014]

Jun 22, 2023

The c.454G>A (p.E152K) alteration is located in exon 7 (coding exon 4) of the RSPO1 gene. This alteration results from a G to A substitution at nucleotide position 454, causing the glutamic acid (E) at amino acid position 152 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
