RESUMO
Clinical data of a case with early-onset epileptic encephalopathy admitted in the Department of Neuroendocrinology, Jinan Children′s Hospital in April 2020 were retrospectively analyzed.A 1-month-old male patient was hospitalized for convulsion for 4 days.The child had repeated seizures in the form of tonic and tonic-spasm seizures, accompanied by feeding difficulties, slow weight gain, and overall developmental delay.Electroencephalogram showed multifocal discharge, atypical hypsarrhythmia, and brain magnetic resonance imaging showed delayed myelination.The whole exome sequencing showed compound heterozygous mutation of the WWOX gene.Topiramate, Levetiracetam and Valporate were ineffective to this case.Genetic testing should be performed timely in patients with early-onset epileptic encephalopathy and overall developmental delay to make a clear etiology and prognosis, thus guiding prenatal diagnostics and genetic counseling.
RESUMO
A retrospective analysis was performed on the clinical data of a case of intellectual developmental disorders with dysmorphic facies and behavioral abnormalities admitted in the Department of Neurology and Endocrinology, Children′s Hospital Affiliated to Shandong University in February 2020.The proband was a 3 years and 6 months old boy, who was hospitalized because of " convulsions for more than 1 year" . Physical examination revealed facial deformities.Gesell developmental schedule showed that adaptive and gross motor behavior development was severely retarded, and fine motor, language and personal-social behavior development was moderately retarded.Brain magnetic resonance imaging suggested schizencephaly.Electroencephalogram results indicated extensive discharges mainly in bilateral anterior head areas, and one myoclonic seizure was detected.Gene detection results disclosed the pathogenic variation of the proband, which was a heterozygote mutation (c.2480_2484del) in FBXO11 gene.High-throughput sequencing technology increases the possibility of identifying potential genetic mutations as the cause of disease.Patients with recurrent seizures, multi-malformation and general developmental delays should undergo gene detection in time to clarify the etiology.This technique can guide prenatal diagnosis and genetic counseling.
