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

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.37).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0052 (792/152238) while in subpopulation AFR AF = 0.0182 (757/41558). AF 95% confidence interval is 0.0171. There are 5 homozygotes in GnomAd4. There are 388 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 792 AD gene.
