DiseaseNail disorder, non-syndromic congenital, 10 (NDNC10) [MIM:614157]: A nail disorder characterized by a variable degree of onychauxis (thick nails), hyponychia, and onycholysis of all nails, with claw-shaped fingernails in some individuals. No other anomalies of ectodermal tissues, including hair, teeth, sweat glands, or skin, are noted, and individuals with dysplastic nails have normal hearing and normal psychomotor development. {ECO:0000269|PubMed:21665003}. Note=The disease is caused by mutations affecting the gene represented in this entry.
DiseaseNote=Rare non-synonymous variants in FZD6 may contribute to neural tube defects, congenital malformations of the central nervous system and adjacent structures related to defective neural tube closure during the first trimester of pregnancy.
DomainLys-Thr-X-X-X-Trp motif interacts with the PDZ doman of Dvl (Disheveled) family members and is involved in the activation of the Wnt/beta-catenin signaling pathway. {ECO:0000250}.
DomainThe FZ domain is involved in binding with Wnt ligands. {ECO:0000250}.
FunctionReceptor for Wnt proteins. Most of frizzled receptors are coupled to the beta-catenin canonical signaling pathway, which leads to the activation of disheveled proteins, inhibition of GSK- 3 kinase, nuclear accumulation of beta-catenin and activation of Wnt target genes. A second signaling pathway involving PKC and calcium fluxes has been seen for some family members, but it is not yet clear if it represents a distinct pathway or if it can be integrated in the canonical pathway, as PKC seems to be required for Wnt-mediated inactivation of GSK-3 kinase. Both pathways seem to involve interactions with G-proteins. May be involved in transduction and intercellular transmission of polarity information during tissue morphogenesis and/or in differentiated tissues. Together with FZD3, is involved in the neural tube closure and plays a role in the regulation of the establishment of planar cell polarity (PCP), particularly in the orientation of asymmetric bundles of stereocilia on the apical faces of a subset of auditory and vestibular sensory cells located in the inner ear (By similarity). {ECO:0000250|UniProtKB:Q61089}.
