FZD6 (Frizzled Class Receptor 6) is a seven-transmembrane receptor that activates both canonical and non-canonical Wnt signaling pathways. It plays essential roles in neural tube closure, planar cell polarity, and hair follicle development. FZD6 is expressed in the developing nervous system and select adult tissues.
FZD6 is a key mediator of PCP signaling:
- Controls convergent extension movements
- Regulates neural tube closure
- Modulates hair follicle orientation
- Affects inner ear stereocilia organization
FZD6 critical for neural tube development:
- Regulates closure of neural folds
- Controls cell polarity in neuroepithelium
- Modulates cytoskeletal dynamics
- Mutations cause neural tube defects
In adult brain, FZD6 modulates:
- Synaptic plasticity
- Hippocampal function
- Cognitive behavior
FZD6 mutations cause:
- Spina bifida
- Craniorachischisis
- Anencephaly
FZD6 dysregulation in AD:
- Altered PCP signaling
- Impaired synaptic function
- Potential therapeutic target
¶ Hair and Skin Disorders
FZD6 linked to:
- Monilethrix (hair disorder)
- Ectodermal dysplasia
FZD6 is expressed in:
- Neural tube: Neuroepithelium
- Brain: Cortex, hippocampus
- Skin: Hair follicles
- Inner ear: Hair cells
- Limb buds: Apical ectodermal ridge

The study of Fzd6 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
