Phenotype-genotype correlations in patients with GNB1 gene variants, including the first three reported Japanese patients to exhibit spastic diplegia, dyskinetic quadriplegia, and infantile spasms.
Autophagy-related X-linked BPAN disease might still be underdiagnosed in female cases of infantile spasms.Skewed X-inactivation will have mainly influenced the uncommon, very early childhood neurodegenerative symptomatology in the present BPAN case.
Through whole exome sequencing, we identified a homozygous missense variant in TLK2 in a patient showing more severe symptoms than those previously described, including cerebellar vermis hypoplasia and West syndrome.
We examined cerebrospinal fluid (CSF) concentrations for neurotrophins, nerve growth factor (β-NGF) and insulin-like growth factor (IGF-1) in children with infantile spasms between 1997 and 2010.
We examined cerebrospinal fluid (CSF) concentrations for neurotrophins, nerve growth factor (β-NGF) and insulin-like growth factor (IGF-1) in children with infantile spasms between 1997 and 2010.
We identified disease-causing single nucleotide variants in 11 out of 45 individuals affecting genes commonly associated with West syndrome (such as CDKL5, ARX) but also in genes predominantly linked to other epileptic disorders (such as DEPDC5, SCN1A, WDR45, AARS).

Here, we performed WES on four trios with West syndrome and identified three loss-of-function DNMs in both CSNK1E (c.885+1G>A) and STXBP1 (splicing, c.1111-2A>G; nonsense, p.(Y519X)).
Whole-exome sequencing identified compound heterozygous mutations in TIMM50 (c.[341 G>A];[805 G>A]) in a boy with West syndrome, optic atrophy, neutropenia, cardiomyopathy, Leigh syndrome, and persistent 3-MGA-uria.
The aim of the study was to characterize the PARS2- related phenotype.Three siblings with biallelic PARS2 mutations presented from birth with infantile spasms, secondary microcephaly, and similar facial dysmorphy.
We identified biallelic mutations in UBA5 in a Japanese boy with intractable West syndrome, profound failure to thrive, and severe cerebral and cerebellar atrophy.
Although IS alters expression of ~30% of the ARC genes in both sexes the transcriptomic effects are 3× more severe in males than their female counterparts, as indicated by the Weighted Pathway Regulation measure.
While ACTH represents the first line of treatment for IS, the even higher efficiency of PMX53 (an antagonist of the complement C5a receptor) in restoring the normal transcriptome was not expected.
We report a female patient with a novel, heterozygous, de novo in-frame deletion in the CASK gene (c.2179-2181 del GTA, p.Val727del) who presents with early onset infantile spasms, hypsarrhythmia on electroencephalogram (EEG), and frontal lobe abnormalities on brain magnetic resonance imaging (MRI) without microcephaly and pontocerebellar hypoplasia.
CPP-115 was found to have high therapeutic potential for the treatment of cocaine addiction and for a variety of epilepsies, has successfully completed a Phase I safety clinical trial, and was found to be effective in the treatment of infantile spasms (West syndrome).
(Asn479Ile)] in PHACTR1, encoding a molecule critical for the regulation of protein phosphatase 1 (PP1) and the actin cytoskeleton, in unrelated Japanese individuals with West syndrome (infantile spasms with intellectual disability).
We report on 2 females with de novo variants in KCNT2 with West syndrome followed by Lennox-Gastaut syndrome or with DEE with migrating focal seizures.
While ACTH represents the first line of treatment for IS, the even higher efficiency of PMX53 (an antagonist of the complement C5a receptor) in restoring the normal transcriptome was not expected.
