Genetic Variant SFRP2:p.Arg291Leu (chr4-153781467-C-A) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2

The NM_003013.3(SFRP2):c.872G>T(p.Arg291Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000093 in 1,612,590 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R291H) has been classified as Uncertain significance.

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]
