Pervasive Developmental Disease

Nicolas Navarro, A Murat Maga
Molar size in Mammals shows considerable disparity and exhibits variation similar to that predicted by the Inhibitory Cascade model. The importance of such developmental systems in favoring evolutionary trajectories is also underlined by the fact that this model can predict macroevolutionary patterns. Using backcross mice, we mapped QTL for molar sizes controlling for their sequential development. Genetic controls for upper and lower molars appear somewhat similar, and regions containing genes implied in dental defects drive this variation...

Rett Syndrome (RTT), which affects approximately 1:10.000 live births, is a X-linked pervasive neuro-developmental disorder which is caused, in the vast majority of cases, by a sporadic mutation in the Methyl-CpG-binding protein-2 (MeCP2) gene. This is a transcriptional activator/repressor with presumed pleiotropic activities. The broad tissue expression of MeCP2 suggests that it may be involved in several metabolic pathways, but the molecular mechanisms which provoke the onset and progression of the syndrome are largely unknown...

Children with autism are often medicated to manage emotional and behavioral symptoms; yet, data on such pharmacotherapy is insufficient. In this study, we investigated the Korean National Health Insurance Claims Database (NHICD) information related to autism incidence and psychotropic medication use. From the 2010-2012 NHICD, we selected a total of 31,919,732 subjects under 19 years old. To examine the diagnostic incidence, we selected patients who had at least one medical claim containing an 10th revision of International Statistical Classification of Diseases and Related Health Problems (ICD-10) code for pervasive developmental disorder, F84, not diagnosed in the previous 360 days...

Juvenile myelomonocytic leukemia (JMML) is a pediatric myeloproliferative neoplasm that bears distinct characteristics associated with abnormal fetal development. JMML has been extensively modeled in mice expressing the oncogenic KrasG12D mutation. However, these models have struggled to recapitulate the defining features of JMML due to in utero lethality, nonhematopoietic expression, and the pervasive emergence of T cell acute lymphoblastic leukemia. Here, we have developed a model of JMML using mice that express KrasG12D in multipotent progenitor cells (Flt3Cre+ KrasG12D mice)...

INTRODUCTION: Rett syndrome (RTT) is a pervasive neurodevelopmental disorder that presents with deficits in brain functioning leading to language and learning regression, characteristic hand stereotypies and developmental delay. Different mutations in the gene implicated in RTT-methyl-CpG-binding protein 2 (MECP2) establishes RTT as a disorder with divergent symptomatology ranging from individuals with severe to milder phenotypes. A reliable and single multidimensional questionnaire is needed that can embrace all symptoms, and the relationships between them, and can map clinically meaningful data to symptomatology across the lifespan in patients with RTT...

BACKGROUND: Rett Syndrome (RTT), caused by a loss-of-function in the epigenetic modulator: X-linked methyl-CpG binding protein 2 (MeCP2), is a pervasive neurological disorder characterized by compromised brain functions, anxiety, severe mental retardation, language and learning disabilities, repetitive stereotyped hand movements and developmental regression. An imbalance in the sympathetic and the parasympathetic nervous system (dysautonomia) and the resulting autonomic storms is a frequent occurrence in patients with RTT...

AIM: Childhood infectious diseases can be associated with later physical and psychological ill health, and the effects of this association may be evident during early childhood development. This study aimed to examine the effects of hospitalisation for early life infection on early childhood development. METHODS: Hospital admission data for infection were obtained from the New South Wales Ministry of Health Admitted Patient Data Collection for 87 026 children, for whom the Australian Early Development Census (AEDC) was completed in their first year of formal schooling (age approximately 5 years)...

Gene expression levels change as an individual ages and responds to environmental conditions. With the exception of humans, such patterns have principally been studied under controlled conditions, overlooking the array of developmental and environmental influences that organisms encounter under conditions in which natural selection operates. We used high-throughput RNA sequencing (RNA-Seq) of whole blood to assess the relative impacts of social status, age, disease, and sex on gene expression levels in a natural population of gray wolves (Canis lupus)...

Around 90% of the mammalian genome undergoes pervasive transcription into various types of small and long regulatory noncoding RNAs, whereas only ∼ 1.5% codes for proteins. Long noncoding RNAs (lncRNAs) constitute diverse classes of sense- and antisense transcripts that are abundantly expressed in the mammalian central nervous system (CNS) in cell type- and developmental stage-specific manners. They are implicated in brain development, differentiation, neuronal plasticity, and other cognitive functions. Mammalian brain requires the vitamin A metabolite all-trans retinoic acid (atRA) for its normal development, differentiation, and cell-fate determination...

BACKGROUND: Previously, investigators suggested that diagnostic substitution from other diagnoses, e.g., mental retardation (MR) and/or cerebral palsy (CP) to pervasive developmental disorder (PDD) is a driving factor behind increases in autism. This study evaluated potential diagnostic substitution among subjects diagnosed with PDD vs. MR or CP by examining birth characteristic overlap. METHODS: SAS(®) and StatsDirect software examined medical records for subjects within the Vaccine Safety Datalink database who were Health Maintenance Organization-enrolled from birth until diagnosed with an International Classification of Disease, 9th revision (ICD-9) outcome of PDD (299...

New technologies are revealing genetic variants of unknown significance (VUS), raising questions about the indications that call for preimplanation genetic diagnosis (PGD). Two couples requesting PGD for VUS are presented. The first couple requested PGD for Lynch syndrome. Whole exome sequencing identified in a healthy male with a family history of Lynch-associated tumours, a MLH1 missense variant. The variant had not been reported as pathogenic, but was predicted as damaging by algorithms. The second couple had a child diagnosed with pervasive developmental disorder and intellectual disability, carrying a microduplication on chr:Xp...

The most commonly identified pathologies in patients with medically intractable epilepsy include focal cortical dysplasia, hippocampal sclerosis, tumors, and remote ischemic damage. Surgery has proven to be an effective therapeutic modality in most of such patients. The coexistence of multiple pathologies in resected tissues is well documented, particularly ganglioglioma and focal cortical dysplasia. Cases of triple pathology are, however, extraordinarily unusual. We report 2 cases of triple pathology including hippocampal sclerosis, ganglioglioma, and focal cortical dysplasia...

Schizophrenia is a pervasive neurodevelopmental disorder that appears to result from genetic and environmental factors. Although the dopamine hypothesis is the driving theory behind the majority of translation research in schizophrenia, emerging evidence suggests that aberrant immune mechanisms in the peripheral and central nervous system influence the etiology of schizophrenia and the pathophysiology of psychotic symptoms that define the illness. The initial interest in inflammatory processes comes from epidemiological data and historical observations, dating back several decades...

BACKGROUND: Pregnancy on dialysis is increasingly being reported. This study evaluates the behavioural profile of the children of mothers on dialysis and the parental stress their mothers undergo when compared with a group of mothers affected by a different chronic disease (microcythaemia) and a group of healthy control mothers. METHODS: Between 2000 and 2012, 23 on-dialysis mothers gave birth to 24 live-born children in Italy (23 pregnancies, 1 twin pregnancy, one of the twins deceased soon after delivery); of these, 16 mothers and 1 father (whose wife died before the inquiry) were included in the study (1 mother had died and the father was unavailable; 2 were not asked to participate because their children had died and 3 were unavailable; children: median age: 8...
