Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 7P and 1B. PM2 PP3_Strong PP5 BS2_Supporting

The NM_012193.4(FZD4):​c.1250G>A​(p.Arg417Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000342 in 1,461,886 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R417W) has been classified as Uncertain significance.

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.

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]

ACMG classification

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.984
• PP5: Variant 11-86951506-C-T is Pathogenic according to our data. Variant chr11-86951506-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 5486.Status of the report is no_assertion_criteria_provided, 0 stars.
• BS2: High AC in GnomAdExome4 at 5 AD,SD,Unknown gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
