Genes affected

FZD1 (HGNC:4038): (frizzled class receptor 1) Members of the 'frizzled' gene family encode 7-transmembrane domain proteins that are receptors for Wnt signaling proteins. The FZD1 protein contains a signal peptide, a cysteine-rich domain in the N-terminal extracellular region, 7 transmembrane domains, and a C-terminal PDZ domain-binding motif. The FZD1 transcript is expressed in various tissues. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.084970295).

Jun 18, 2024

The c.86G>A (p.R29Q) alteration is located in exon 1 (coding exon 1) of the FZD1 gene. This alteration results from a G to A substitution at nucleotide position 86, causing the arginine (R) at amino acid position 29 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
