CCDC141 (Coiled-Coil Domain Containing 141): CCDC141 is a gene that encodes a protein involved in the formation and function of cilia and flagella—cellular structures essential for movement, fluid flow, and signalling. By supporting proper cilia organisation, CCDC141 influences processes such as cell motility, sensory perception, and developmental signalling. Mutations in this gene have been linked to ciliopathies, a group of disorders caused by dysfunctional cilia that can affect multiple organs.
