Abstract
BACKGROUND
Infantile spasms are rare epileptic syndromes associated with neurodevelopment and genes. The NEXMIF gene, identified as KIDLIA, KIAA2022 or Xpn, is a gene of unknown biological identity located on the q13.2 X chromosome.
CASE DESCRIPTION
We presented a 4-month-old infant with a diagnosis of infantile spasms with NEXMIF mutation. Clinical manifestations include psychomotor retardation, loss of consciousness, and seizures. After oral therapy with vigabatrin, sodium valproate, and levetiracetam, the syndrome was alleviated and no recurrence was observed during one month of follow-up.
CONCLUSIONS
A loss-of-function mutation in the NEXMIF gene has been reported. There are few reports on this mutation worldwide. This study provides a new idea for the clinical treatment of infantile spasms.
