Genes affected

SFRP2 (HGNC:10777): (secreted frizzled related protein 2) This gene encodes a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled proteins. SFRPs act as soluble modulators of Wnt signaling. Methylation of this gene is a potential marker for the presence of colorectal cancer. [provided by RefSeq, Jul 2008]

ENSG00000280241 (HGNC:58900):
