Genes affected

SFRP1 (HGNC:10776): (secreted frizzled related protein 1) 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. Members of this family act as soluble modulators of Wnt signaling; epigenetic silencing of SFRP genes leads to deregulated activation of the Wnt-pathway which is associated with cancer. This gene may also be involved in determining the polarity of photoreceptor cells in the retina. [provided by RefSeq, Sep 2009]

Nov 30, 2022

The c.502G>T (p.A168S) alteration is located in exon 1 (coding exon 1) of the SFRP1 gene. This alteration results from a G to T substitution at nucleotide position 502, causing the alanine (A) at amino acid position 168 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
