STK9 or CDKL5 is a member of Ser/Thr protein kinase family which has protein kinase activity and is associated with X-linked infantile spasm syndrome (ISSX), also known as X-linked West syndrome, and Rett syndrome (RTT). STK9 can control nuclear speckle morphology by regulating the phosphorylation state of splicing regulatory proteins, and may be involved indirectly in pre-mRNA processing, by controlling splicing factor dynamics (1). The mutations in the STK9 is a major cause of infantile spasms and early epileptic seizures in female patients, and of a later intractable seizure disorder (2).
