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 signaling. By supporting proper cilia organization, CCDC141 influences processes such as cell motility, sensory perception, and developmental signaling. Mutations in this gene have been linked to ciliopathies, a group of disorders caused by dysfunctional cilia that can affect multiple organs.
