Genes affected

MCIDAS (HGNC:40050): (multiciliate differentiation and DNA synthesis associated cell cycle protein) This gene encodes a member of the geminin family of proteins. The encoded nuclear protein is required for the generation of multiciliated cells in respiratory epithelium. Mutations in this gene cause a rare mucociliary clearance disorder associated with recurring respiratory infections in human patients, known as reduced generation of multiple motile cilia (RGMC).
