Gene: CDKL5
Alternate names for this Gene: CFAP247|DEE2|EIEE2|ISSX|STK9
Gene Summary: This gene is a member of Ser/Thr protein kinase family and encodes a phosphorylated protein with protein kinase activity. Mutations in this gene have been associated with X-linked infantile spasm syndrome (ISSX), also known as X-linked West syndrome, and Rett syndrome (RTT). Alternate transcriptional splice variants have been characterized.
Gene is located in Chromosome: X
Location in Chromosome : Xp22.13
Description of this Gene: cyclin dependent kinase like 5
Type of Gene: protein-coding
