Genes affected

SFRP4 (HGNC:10778): (secreted frizzled related protein 4) Secreted frizzled-related protein 4 (SFRP4) 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. The expression of SFRP4 in ventricular myocardium correlates with apoptosis related gene expression. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.05408582).
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000263 (4/152152) while in subpopulation EAS AF = 0.000578 (3/5188). AF 95% confidence interval is 0.000157. There are 0 homozygotes in GnomAd4. There are 0 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
