frizzled class receptor 6

Also known as: FZ-6, FZ6, HFZ6, NDNC1, NDNC10

NCBI Gene: 8323 ENSG00000164930 UniProt: O60353 OMIM: 603409

This gene encodes a 7-transmembrane receptor for Wnt signaling proteins that regulates canonical Wnt/beta-catenin signaling and planar cell polarity, particularly in inner ear sensory cells and during neural tube closure. Autosomal recessive mutations cause nonsyndromic congenital nail disorder, with the gene showing low constraint to loss-of-function variation. The phenotype appears to be congenital and primarily affects nail development without other syndromic features.

OMIM ResearchSummary from RefSeq, OMIM, UniProt

This gene represents a member of the 'frizzled' gene family, which encode 7-transmembrane domain proteins that are receptors for Wnt signaling proteins. The protein encoded by this family member contains a signal peptide, a cysteine-rich domain in the N-terminal extracellular region, and seven transmembrane domains, but unlike other family members, this protein does not contain a C-terminal PDZ domain-binding motif. This protein functions as a negative regulator of the canonical Wnt/beta-catenin signaling cascade, thereby inhibiting the processes that trigger oncogenic transformation, cell proliferation, and inhibition of apoptosis. Alternative splicing results in multiple transcript variants, some of which do not encode a protein with a predicted signal peptide.[provided by RefSeq, Aug 2011]

Interpreting a novel variant

Loss of function is the curated mechanism (Gene2Phenotype), though the gene is not strongly LoF-constrained in the population — weigh truncating variants against that tolerance.Curated gene-level mechanism — a prior for triage, not a per-variant call.
