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

Verdict is Benign. Variant got -8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.019672394).
• BP6: Variant 7-37907636-C-T is Benign according to our data. Variant chr7-37907636-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 3160908.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000137 (20/1459720) while in subpopulation MID AF= 0.000182 (1/5502). AF 95% confidence interval is 0.0000652. There are 0 homozygotes in gnomad4_exome. There are 14 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.

Sep 29, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
