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. [provided by RefSeq, Jul 2008]
PRSS23 (HGNC:14370): (serine protease 23) This gene encodes a conserved member of the trypsin family of serine proteases. Mouse studies found a decrease of mRNA levels of this gene after ovulation was induced. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

The FZD4 c.766A>G variant is predicted to result in the amino acid substitution p.Ile256Val. This variant has been reported in an individual with retinopathy of prematurity (MacDonald et al 2005. PubMed ID: 15733276). This variant is reported in 0.088% of alleles in individuals of European (Non-Finnish) descent in gnomAD, including one homozygous individual in the latest dataset (https://gnomad.broadinstitute.org/variant/11-86951990-T-C?dataset=gnomad_r4). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
