CDKL5 stands for cyclin-dependent kinase-like 5, a protein whose gene is located on the X chromosome. The CDKL5 gene provides instructions for making a protein that is essential in forming the connections for normal brain development, with mutations causing a deficiency in the protein level. Most children affected by CDKL5 deficiency disorder (about 90 percent of whom are girls) suffer from seizures that begin in the first few months of life. Most cannot walk, talk, or feed themselves, and many are confined to wheelchairs, dependent on others for everything. Many also suffer with scoliosis, visual impairment, sensory problems, and gastrointestinal difficulties.
