Congenital thrombotic thrombocytopenic purpura is a rare autosomal recessive disorder presenting with hemolytic anemia, thrombocytopenia, micro vascular thrombosis, and end organ damage. Here, we present a case of a 7-year-old girl having recurrent neonatal hemolysis, developmental delay, frequent seizures, and thrombocytopenia. Characteristic clinical picture and gene sequencing of a disintegrin and metalloproteinase with thrombospondin motifs 13 confirmed the diagnosis of Upshaw-Schulman syndrome. She was treated successfully with plasma infusion...

At the onset, differentiation between abnormal non-epileptic movements, and epileptic seizures presenting in early life is difficult as is clinical diagnosis and prognostic evaluation of the various seizure disorders presenting at this age. Seizures starting in the first year of life including the neonatal period might have a favorable course, such as in infants presenting with benign familial neonatal epilepsy, febrile seizures simplex or acute symptomatic seizures. However, in some cases, the onset of seizures at birth or in the first months of life have a dramatic evolution with severe cerebral impairment...

Background: With only 11 patients reported, 5p tetrasomy belongs to rare postnatal findings. Most cases are due to small supernumerary marker chromosomes (sSMCs) or isochromosomes. The patients share common but unspecific symptoms such as developmental delay, seizures, ventriculomegaly, hypotonia, and fifth finger clinodactyly. Simple interstitial duplications leading to trisomies of parts of 5p are much more frequent and better described. Duplications encompassing 5p13.2 cause a defined syndrome with macrocephaly, distinct facial phenotype, heart defects, talipes equinovarus, feeding difficulties, respiratory distress and anomalies of the central nervous system, developmental delay and hypotonia...

High resolution chromosomal microarray analysis (CMA) has facilitated the identification of small chromosomal rearrangements throughout the genome, associated with various neurodevelopmental phenotypes, including ID/DD. Recently, it became evident that intellectual disability (ID)/developmental delay (DD) can occur with associated co-morbidities like epileptic seizures, autism and additional congenital anomalies. These observations require whole genome approach in order to detect the genetic causes of these complex disorders...

OBJECTIVE: Pathogenic variants in SCN1A can give rise to extremely variable disease severities that may be indistinguishable at their first presentation. We aim to find clinical features that can help predict the evolution of seizures into Dravet syndrome and clinical features that predict cognitive outcome in Dravet syndrome. We specifically investigate the role of contraindicated medication (CIM) as a possible modifier of cognitive decline. METHODS: A cohort of 164 Dutch participants with SCN1A-related seizures was evaluated...

Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) develops in association with systemic as well as central nervous system (CNS) viral or bacterial infections. AESD is most often noted with influenza or human herpesvirus 6 infection in previously healthy infants. However, AESD has also been reported in an infant with developmental retardation and in a mentally and motor-disabled adolescent. Here, we report the case of a 4- year-old female with significant development delay due to spinal muscular atrophy, who developed AESD during Streptococcus sanguinis sepsis with no apparent CNS infection...

Xia-Gibbs syndrome (XGS: OMIM # 615829) results from de novo truncating mutations within the AT-Hook DNA Binding Motif Containing 1 gene (AHDC1). To further define the phenotypic and molecular spectrum of this disorder, we established an XGS Registry and recruited patients from a worldwide pool of approximately 60 probands. Additional de novo truncating mutations were observed among 25 individuals, extending both the known number of mutation sites and the range of positions within the coding region that were sensitive to alteration...

Molybdenum cofactor deficiency is a rare metabolic disorder manifesting with early onset seizures, developmental delay, microcephaly, and spasticity. In this report, we describe a three-month-old infant with neonatal onset, poorly controlled seizures, developmental delay, microcephaly, spastic quadriparesis and visual insufficiency. Magnetic resonance imaging of brain had shown cystic encephalomalacia involving bilateral parieto-occipital lobe and elevated lactate in magnetic resonance spectroscopy. Restricted diffusion noted along the corticospinal tract in our case is a novel imaging finding in patients with molybdenum cofactor deficiency...

WDR45 gene-associated neurodegeneration with brain iron accumulation (NBIA), referred to as beta-propeller protein-associated neurodegeneration (BPAN), is a rare disorder that presents with a very nonspecific clinical phenotype in children constituting global developmental delay. This case report illustrates the power of a combination of trio exome sequencing, in silico splicing analysis, and mRNA analysis to provide sufficient evidence for pathogenicity of a relatively intronic variant in WDR45, and in so doing, find a genetic diagnosis for a 6-year-old patient with developmental delay and seizures, a diagnosis which may otherwise have only been found once the characteristic MRI patterns of the disease became more obvious in young adulthood...

V-type proton (H+) ATPase (v-ATPase) is a multi-subunit proton pump that regulates pH homeostasis in all eukaryotic cells; in neurons, v-ATPase plays additional and unique roles in synapse function. Through whole exome sequencing, we identified de novo heterozygous mutations (p.Pro27Arg, p.Asp100Tyr, p.Asp349Asn, p.Asp371Gly) in ATP6V1A, encoding the A subunit of v-ATPase, in four patients with developmental encephalopathy with epilepsy. Early manifestations, observed in all patients, were developmental delay and febrile seizures, evolving to encephalopathy with profound delay, hypotonic/dyskinetic quadriparesis and intractable multiple seizure types in two patients (p...

Vanishing white matter disease (VWM) is one of the most prevalent inherited leukoencephalopathies in childhood. Infantile VWM is more severe but less understood than the classic early childhood type. We performed a follow-up study on 14 infantile and 26 childhood patients to delineate the natural history and neuroimaging features of VWM. Infantile and childhood patients shared similarities in the incidence of epileptic seizure (35.7 vs. 38.5%) and episodic aggravation (92.9 vs. 84.6%). Developmental delay before disease onset was more common in infantile patients...

REVIEW
Sara M Blazejewski, Sarah A Bennison, Trevor H Smith, Kazuhito Toyo-Oka
Chromosome 17p13.3 is a region of genomic instability that is linked to different rare neurodevelopmental genetic diseases, depending on whether a deletion or duplication of the region has occurred. Chromosome microdeletions within 17p13.3 can result in either isolated lissencephaly sequence (ILS) or Miller-Dieker syndrome (MDS). Both conditions are associated with a smooth cerebral cortex, or lissencephaly, which leads to developmental delay, intellectual disability, and seizures. However, patients with MDS have larger deletions than patients with ILS, resulting in additional symptoms such as poor muscle tone, congenital anomalies, abnormal spasticity, and craniofacial dysmorphisms...

Recently, haploinsufficiency of PURA has been identified as an essential cause of 5q31.3 microdeletion syndrome, which is characterized by severe psychomotor developmental delay, epilepsy, distinctive features, and delayed myelination. A new 5q31.2-q31.3 microdeletion that included PURA was identified in a patient with infantile spasms. Approximately 50% of patients with PURA -related neurodevelopmental disorders exhibited epilepsy regardless of whether they harbor a 5q31.3 deletion or PURA mutation. Patients with the 5q31...

Chromosome 1p36 deletion is the most common subtelomeric deletion syndrome characterized by variable features including unique facial appearance, intellectual disability, developmental delay, cardiac defects, seizures and hypotonia. Here, we report a patient with developmental delay, dilated cardiomyopathy, seizures, hirsutism and cutis laxa who was diagnosed with 1p36 deletion syndrome by chromosome microarray analysis. This patient is the first reported case of 1p36 deletion syndrome associated with cutis laxa and our results suggest that the 1p36 region contains one or more genes relevant to cutis laxa...
