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]

The c.544G>T (p.D182Y) alteration is located in exon 2 (coding exon 2) of the SFRP2 gene. This alteration results from a G to T substitution at nucleotide position 544, causing the aspartic acid (D) at amino acid position 182 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
