KOL-Index: 146 Biallelic 4-hydroxyphenylpyruvate dioxygenase-like protein (HPDL) variants were recently reported as a cause of progressive and incurable neurodegenerative diseases ranging from neonatal-onset leukoencephalopathy with severe neurodevelopmental delay to spastic paraplegia. Although the physiological function of HPDL remains unknown, its subcellular localization in the mitochondria has been ...

KOL-Index: 33 Objective: Accurate estimation of the epileptogenic zone (EZ) is essential for favorable outcomes in epilepsy surgery. Conventional ictal electrocorticography (ECoG) onset is generally used to detect the EZ but is insufficient in achieving seizure-free outcomes. By contrast, high-frequency oscillations (HFOs) could be useful markers of the EZ. Hence, we aimed to detect the EZ using ...

KOL-Index: 29 Isolated 3-methylcrotonyl-CoA carboxylase (MCC) deficiency appears to be the most frequent organic aciduria detected in tandem mass spectrometry (MS/MS) screening programs in the United States, Australia, and Europe. A pilot study of newborn screening using MS/MS has recently been commenced in Japan. Our group detected two asymptomatic MCC deficiency patients by the pilot screening and ...

KOL-Index: 25 West syndrome, which is narrowly defined as infantile spasms that occur in clusters and hypsarrhythmia on EEG, is the most common early-onset epileptic encephalopathy (EOEE). Patients with West syndrome may have clear etiologies, including perinatal events, infections, gross chromosomal abnormalities, or cases followed by other EOEEs. However, the genetic etiology of most cases of West ...

KOL-Index: 25 Mutations involving the voltage-gated sodium channel alpha(I) gene SCN1A are major genetic causes of childhood epileptic disorders, as typified by Dravet syndrome. Here we investigated the upstream regions of the SCN1A 5' noncoding exons and found two major regions with promoter activity. These two major promoters were simultaneously active in various brain regions and in most neurons. Using ...

KOL-Index: 24 Molybdenum cofactor deficiency (MoCD) is an autosomal recessive inborn error of metabolism that results from mutations in genes involved in molybdenum cofactor (Moco) biosynthesis. MoCD is characterized clinically by intractable seizures and severe, rapidly progressing neurodegeneration leading to death in early childhood in the majority of known cases. We report on a patient with an unusual ...

KOL-Index: 23 Renal tubular dysgenesis (RTD) is a developmental abnormality of the renal proximal tubules found in patients with Potter syndrome. We report a female newborn with RTD who has survived for more than 18 months. Infusions of fresh frozen plasma (FFP) in the early neonatal period were effective in raising and maintaining her blood pressure. Peritoneal dialysis was required until the appearance ...

KOL-Index: 23 Childhood cerebral ALD is a rapidly progressive and neurodegenerative disorder for which HSCT is the curative therapy if carried out at early stages. We successfully treated two patients of childhood cerebral ALD by CBT with RIC. The proband was a seven-yr-old boy whose brain MRI severity score (Loes score) was 14.5. Unrelated CBT was performed in five wk. To minimize conditioning ...

KOL-Index: 22 OBJECT: Corpus callosotomy is usually intended to alleviate-not to achieve total control of-epileptic seizures. A few patients experience complete seizure control after callosotomy, but the associated clinical factors are unknown. The object of this study was to investigate clinical factors associated with long-term seizure remission after total corpus callosotomy in patients with infantile ...

KOL-Index: 22 Recent studies suggest that impaired transcription or mitochondrial translation of small RNAs can cause abnormal myelination. A polynucleotide phosphorylase (PNPase) encoded by PNPT1 facilitates the import of small RNAs into mitochondria. PNPT1 mutations have been reported in patients with neurodevelopmental diseases with mitochondrial dysfunction. We report here 2 siblings with PNPT1 ...
