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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2023The c.449A>G (p.Y150C) alteration is located in exon 1 (coding exon 1) of the SFRP1 gene. This alteration results from a A to G substitution at nucleotide position 449, causing the tyrosine (Y) at amino acid position 150 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
