Genes affected

FZD4 (HGNC:4042): (frizzled class receptor 4) This gene is a member of the frizzled gene family. Members of this family encode seven-transmembrane domain proteins that are receptors for the Wingless type MMTV integration site family of signaling proteins. Most frizzled receptors are coupled to the beta-catenin canonical signaling pathway. This protein may play a role as a positive regulator of the Wingless type MMTV integration site signaling pathway. A transcript variant retaining intronic sequence and encoding a shorter isoform has been described, however, its expression is not supported by other experimental evidence.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PM1

In a domain FZ (size 121) in uniprot entity FZD4_HUMAN there are 47 pathogenic changes around while only 1 benign (98%) in NM_012193.4

BP4

Computational evidence support a benign effect (MetaRNN=0.10089463).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.000323 (472/1461182) while in subpopulation EAS AF= 0.00703 (279/39684). AF 95% confidence interval is 0.00635. There are 2 homozygotes in gnomad4_exome. There are 237 alleles in male gnomad4_exome subpopulation. Median coverage is 33.

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
