Genes affected

SFRP5 (HGNC:10779): (secreted frizzled related protein 5) Secreted frizzled-related protein 5 (SFRP5) is 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. SFRP5 and SFRP1 may be involved in determining the polarity of photoreceptor cells in the retina. SFRP5 is highly expressed in the retinal pigment epithelium, and moderately expressed in the pancreas. [provided by RefSeq, Jul 2008]

The c.715G>A (p.D239N) alteration is located in exon 3 (coding exon 3) of the SFRP5 gene. This alteration results from a G to A substitution at nucleotide position 715, causing the aspartic acid (D) at amino acid position 239 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
