	CDD is caused by mutations in the CDKL5 gene, which provides instructions for making a protein that is essential for normal brain development. This protein acts as a [[kinase]], which is a type of enzyme that modifies other proteins by adding a phosphate group (a process called [[phosphorylation]]). The CDKL5 protein is thought to play a key role in regulating the connections between neurons (synapses) and the formation of dendritic spines, which are small outgrowths from neurons that help transmit signals from one neuron to another.

'''CDKL5 deficiency disorder''' (CDD) is a rare [[neurological disorder]] that primarily affects females and is characterized by early-onset [[epileptic seizures]], severe [[intellectual disability]], and [[motor impairment]]. The disorder is caused by mutations in the [[CDKL5]] gene, which is involved in brain development.

==Etiology==

CDD is caused by mutations in the CDKL5 gene, which provides instructions for making a protein that is essential for normal brain development.
