Associations Pending Confirmation See Approximately two-thirds of affected infants will have a detectable underlying neurological abnormality, but still little is known about the pathophysiological basis for infantile spasms, and treatment remains problematic.
Psychomotor retardation is frequently found at follow-up. Onset was on the same day when they were 6 months old. Not all treatments are licensed for use in all countries.
Seizure onset occurred earlier in life than dystonia, which was severe and progressed to quadriplegic dyskinesia. The phenotype is also observed in other genetic disorders, including GLUT1 deficiency syndrome ; glycine encephalopathy ; Aicardi-Goutieres syndrome ; and in males with MECP2 mutationsamong others.
She developed severe intractable myoclonic seizures at age 4 months, consistent with epileptic encephalopathy. Further research using large studies with robust methodology is required.

Expert curators review the literature and organize it to facilitate your work. Although males with ARX mutations are often more severely affected, female mutation carriers may also be affected Kato et al.
Feinberg and Leahy reported X-linked recessive inheritance of infantile seizures in a family in which 5 males in spzzm sibships spanning 3 generations were affected.
They considered it a candidate gene underlying ISSX, primarily on the basis of its expression pattern in fetal, infant, and adult brain.
