A syndrome characterized by multiple abnormalities, MENTAL RETARDATION, and movement disorders. Present usually are skull and other abnormalities, frequent infantile spasms (SPASMS, INFANTILE); easily provoked and prolonged paroxysms of laughter (hence "happy"); jerky puppetlike movements (hence "puppet"); continuous tongue protrusion; motor retardation; ATAXIA; MUSCLE HYPOTONIA; and a peculiar facies. It is associated with maternal deletions of chromosome 15q11-13 and other genetic abnormalities. (From Am J Med Genet 1998 Dec 4;80(4):385-90; Hum Mol Genet 1999 Jan;8(1):129-35)

In vivo nuclease hypersensitivity studies reveal multiple sites of parental origin-dependent differential chromatin conformation in the 150 kb SNRPN transcription unit. (1/228)

Human chromosome region 15q11-q13 contains a cluster of oppositely imprinted genes. Loss of the paternal or the maternal alleles by deletion of the region or by uniparental disomy 15 results in Prader-Willi syndrome (PWS) or Angelman syndrome (AS), respectively. Hence, the two phenotypically distinct neurodevelopmental disorders are caused by the lack of products of imprinted genes. Subsets of PWS and AS patients exhibit 'imprinting mutations', such as small microdeletions within the 5' region of the small nuclear ribonucleoprotein polypeptide N ( SNRPN ) transcription unit which affect the transcriptional activity and methylation status of distant imprinted genes throughout 15q11-q13 in cis. To elucidate the mechanism of these long-range effects, we have analyzed the chromatin structure of the 150 kb SNRPN transcription unit for DNase I- and Msp I-hypersensitive sites. By using an in vivo approach on lymphoblastoid cell lines from PWS and AS individuals, we discovered that the SNRPN exon 1 is flanked by prominent hypersensitive sites on the paternal allele, but is completely inaccessible to nucleases on the maternal allele. In contrast, we identified several regions of increased nuclease hypersensitivity on the maternal allele, one of which coincides with the AS minimal microdeletion region and another lies in intron 1 immediately downstream of the paternal-specific hypersensitive sites. At several sites, parental origin-specific nuclease hypersensitivity was found to be correlated with hypermethylation on the allele contributed by the other parent. The differential parental origin-dependent chromatin conformations might govern access of regulatory protein complexes and/or RNAs which could mediate interaction of the region with other genes.  (+info)

Genomic imprinting: implications for human disease. (2/228)

Genomic imprinting refers to an epigenetic marking of genes that results in monoallelic expression. This parent-of-origin dependent phenomenon is a notable exception to the laws of Mendelian genetics. Imprinted genes are intricately involved in fetal and behavioral development. Consequently, abnormal expression of these genes results in numerous human genetic disorders including carcinogenesis. This paper reviews genomic imprinting and its role in human disease. Additional information about imprinted genes can be found on the Genomic Imprinting Website at http://www.geneimprint.com.  (+info)

Parental view of epilepsy in Angelman syndrome: a questionnaire study. (3/228)

PURPOSE: To explore parents' opinions and concerns about seizures, anticonvulsants, and the effect of treatment in children with Angelman syndrome. DESIGN: A postal questionnaire was sent to members of one of the UK lay groups for Angelman syndrome (ASSERT) who had a child affected by Angelman syndrome. The questionnaire requested general medical information and information about the epilepsy, its treatment, and treatment responses. RESULTS: One hundred and fifty questionnaires were sent out with an ASSERT routine mailing and 78 completed questionnaires were returned. Forty three patients were boys and 35 were girls; ages ranged from 1.7 to 25 years (mean 7.5 years). The overall general clinical and cytogenetic data were mostly consistent with previous reports. Epilepsy was reported in 68 children, most of whom had a detectable cytogenetic deletion. The most common seizure types reported by the families were absence seizures, tonic clonic seizures, drop attacks, and myoclonic seizures; in four patients only febrile seizures occurred. The age at onset of the seizures was < 2 years in more than half of the patients. Anti-epileptic drug treatment with valproate (VPA), clonazepam (CZP), and lamotrigine (LTG) as monotherapy or a combination of VPA and CZP or VPA and LTG was more often viewed favourably and considered effective with fewer side effects on the child's behaviour and alertness, versus more frequent adverse effects and increased frequency and severity of seizures with carbamazepine (CBZ) and vigabatrin (VGB) in monotherapy or in combination with other anti-epileptic drugs. Seizures did tend to improve with age but were still present and disabling at older ages. CONCLUSIONS: This is the first study to record parents' opinions about seizures, anti-epileptic drugs, and treatment responses in children with Angelman syndrome, and it is one of the largest series on epilepsy and Angelman syndrome to be reported to date.  (+info)

Phenotype-genotype correlation in 20 deletion and 20 non-deletion Angelman syndrome patients. (4/228)

Angelman syndrome (AS) is a neurodevelopmental disorder caused by the absence of a maternal contribution to chromosome 15q11-q13. There are four classes of AS according to molecular or cytogenetic status: maternal microdeletion of 15q11-q13 (approximately 70% of AS patients); uniparental disomy (UPD); defects in a putative imprinting centre (IM); the fourth includes 20-30% of AS individuals with biparental inheritance and a normal pattern of allelic methylation in 15q11-q13. Mutations of UBE3A have recently been identified as causing AS in the latter group. Few studies have investigated the phenotypic differences between these classes. We compared 20 non-deletion to 20 age-matched deletion patients and found significant phenotypic differences between the two groups. The more severe phenotype in the deletion group may suggest a contiguous gene syndrome.  (+info)

Large genomic duplicons map to sites of instability in the Prader-Willi/Angelman syndrome chromosome region (15q11-q13). (5/228)

The most common etiology for Prader-Willi syndrome and Angelman syndrome is de novo interstitial deletion of chromosome 15q11-q13. Deletions and other recurrent rearrangements of this region involve four common 'hotspots' for breakage, termed breakpoints 1-4 (BP1-BP4). Construction of an approximately 4 Mb YAC contig of this region identified multiple sequence tagged sites (STSs) present at both BP2 and BP3, suggestive of a genomic duplication event. Interphase FISH studies demonstrated three to five copies on 15q11-q13, one copy on 16p11.1-p11.2 and one copy on 15q24 in normal controls, while analysis on two Class I deletion patients showed loss of approximately three signals at 15q11-q13 on one homolog. Multiple FISH signals were also observed at regions orthologous to both human chromosomes 15 and 16 in non-human primates, including Old World monkeys, suggesting that duplication of this region may have occurred approximately 20 million years ago. A BAC/PAC contig for the duplicated genomic segment (duplicon) demonstrated a size of approximately 400 kb. Surprisingly, the duplicon was found to contain at least seven different expressed sequence tags representing multiple genes/pseudogenes. Sequence comparison of STSs amplified from YAC clones uniquely mapped to BP2 or BP3 showed two different copies of the duplicon within BP3, while BP2 comprised a single copy. The orientation of BP2 and BP3 are inverted relative to each other, whereas the two copies within BP3 are in tandem. The presence of large duplicated segments on chromosome 15q11-q13 provides a mechanism for homologous unequal recombination events that may mediate the frequent rearrangements observed for this chromosome.  (+info)

Chromosome breakage in the Prader-Willi and Angelman syndromes involves recombination between large, transcribed repeats at proximal and distal breakpoints. (6/228)

Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are distinct neurobehavioral disorders that most often arise from a 4-Mb deletion of chromosome 15q11-q13 during paternal or maternal gametogenesis, respectively. At a de novo frequency of approximately.67-1/10,000 births, these deletions represent a common structural chromosome change in the human genome. To elucidate the mechanism underlying these events, we characterized the regions that contain two proximal breakpoint clusters and a distal cluster. Novel DNA sequences potentially associated with the breakpoints were positionally cloned from YACs within or near these regions. Analyses of rodent-human somatic-cell hybrids, YAC contigs, and FISH of normal or rearranged chromosomes 15 identified duplicated sequences (the END repeats) at or near the breakpoints. The END-repeat units are derived from large genomic duplications of a novel gene (HERC2), many copies of which are transcriptionally active in germline tissues. One of five PWS/AS patients analyzed to date has an identifiable, rearranged HERC2 transcript derived from the deletion event. We postulate that the END repeats flanking 15q11-q13 mediate homologous recombination resulting in deletion. Furthermore, we propose that active transcription of these repeats in male and female germ cells may facilitate the homologous recombination process.  (+info)

Angelman syndrome resulting from UBE3A mutations in 14 patients from eight families: clinical manifestations and genetic counselling. (7/228)

Angelman syndrome (AS) is a neurological disorder with a heterogeneous genetic aetiology. It most frequently results from a de novo interstitial deletion in the 15q11-q13 region, but in a few cases it is caused by paternal uniparental disomy (UPD) or an imprinting mutation. The remaining 20 to 30% of AS patients exhibit biparental inheritance and a normal pattern of allelic methylation in the 15q11-q13 region. In this latter group, mutations in the UBE3A gene have recently been shown to be a cause of AS. Here we describe the phenotypic expression in 14 AS cases involving eight UBE3A mutations. These comprise 11 familial cases from five families and three sporadic cases. Subtle differences from the typical phenotype of AS were found. Consistent manifestations were psychomotor delay, a happy disposition, a hyperexcitable personality, EEG abnormalities, and mental retardation with severe speech impairment. The other main manifestations of AS, ataxia, epilepsy, and microcephaly, were either milder or absent in various combinations among the patients. In addition, myoclonus of cortical origin was frequently observed with severe fits inducing myoclonic seizures. The majority of the patients were overweight. This study showed that ataxia, myoclonus, EEG abnormalities, speech impairment, characteristic behavioural phenotype, and abnormal head circumference are attributable to a deficiency in the maternally inherited UBE3A allele. Furthermore, analysis of mutation transmission showed an unexpectedly high rate of somatic mosaicism in normal carriers. These data have important consequences for genetic counselling.  (+info)

A transgene insertion creating a heritable chromosome deletion mouse model of Prader-Willi and angelman syndromes. (8/228)

Prader-Willi syndrome (PWS) and Angelman syndrome (AS) result from the loss of function of imprinted genes in human chromosome 15q11-q13. The central part of mouse chromosome 7 is homologous to human 15q11-q13, with conservation of both gene order and imprinted features. We report here the characterization of a transgene insertion (Epstein-Barr virus Latent Membrane Protein 2A, LMP2A) into mouse chromosome 7C, which has resulted in mouse models for PWS and AS dependent on the sex of the transmitting parent. Epigenotype (allelic expression and DNA methylation) and fluorescence in situ hybridization analyses indicate that the transgene-induced mutation has generated a complete deletion of the PWS/AS-homologous region but has not deleted flanking loci. Because the intact chromosome 7, opposite the deleted homolog, maintains the correct imprint in somatic cells of PWS and AS mice and establishes the correct imprint in male and female germ cells of AS mice, homologous association and replication asynchrony are not part of the imprinting mechanism. This heritable-deletion mouse model will be particularly useful for the identification of the etiological genes and mechanisms, phenotypic basis, and investigation of therapeutic approaches for PWS.  (+info)

Angelman syndrome (AS) is a rare neurogenetic disorder that affects approximately one in 15,000 people - about 500,000 individuals worldwide. Children and adults with AS typically have balance issues, motor impairment and debilitating seizures. Some individuals never walk. Most do not speak. Disrupted sleep cycles also can be a serious challenge to the individual and caretaker(s). Individuals with AS require continuous care and are unable to live independently. They have a normal life expectancy. This is life today for people living with Angelman syndrome, but hope is here. Scientists believe that AS has the greatest potential for being cured when compared to other neurogenetic disorders, and FAST (Foundation for Angelman Syndrome Therapeutics) has a plan well underway to achieve just that..

Clinicians have qualitatively described rhythmic delta activity as a prominent EEG abnormality in individuals with Angelman syndrome, but this phenotype has yet to be rigorously quantified in the clinical population or validated in a preclinical model. Here, we sought to quantitatively measure delta rhythmicity and evaluate its fidelity as a biomarker. We quantified delta oscillations in mouse and human using parallel spectral analysis methods and measured regional, state-specific, and developmental changes in delta rhythms in a patient population. Delta power was broadly increased and more dynamic in both the Angelman syndrome mouse model, relative to wild-type littermates, and in children with Angelman syndrome, relative to age-matched neurotypical controls. Enhanced delta oscillations in children with Angelman syndrome were present during wakefulness and sleep, were generalized across the neocortex, and were more pronounced at earlier ages. Delta rhythmicity phenotypes can serve as reliable

Angelman syndrome is a genetic condition characterized by a deletion of part of maternal chromosome 15 (15q11-13), which is associated with severe mental retardation, ataxic (uncoordinated) gait, tremulousness, and jerky movements. Although not yet fully studied, the critical region of the 15th chromosome contains several genes that code for GABA-A receptor subunits. The GABA-A receptor is the most common GABA receptor in the brain. GABA-A receptors regulate the flow of chloride ions (Cl-) across neuron membranes, which decreases neuron excitability. In Angelman syndrome, the lack of adequate GABA-A influence increases neuronal (CNS) excitability and results in myoclonic (muscle twitching) activity, which was reported to be significantly reduced in 5 patients by treatment with piracetam [Guerrini et al., 1966]..

Purpose: To determine: 1) If a 15q11-13 deletion was transmitted from a female with Angelman syndrome to her fetus, and 2) If the UBE3A gene was functionally imprinted in fetal eye. Methods: Individuals were genotyped by microsatellite analysis. DNA methylation imprints were assessed by Southern blot analysis and methylationspecific PCR. Expression was analyzed by RT-PCR. Results: The mother and fetus inherited large deletions of maternal 15q11-13 and demonstrated paternal-only DNA methylation imprints along 15q11-13. UBE3A was paternally expressed in eye tissue from the fetus with Angelman syndrome. Conclusions: We show that females with Angelman syndrome are fully capable of reproduction and that UBE3A is not imprinted in fetal eye.

Angelman Syndrome (AS) is a neurogenetic disorder that is classically characterized by excessive laughter and a happy demeanor. Aggression, sleep disorders and epilepsy are other phenotypes associated with this disorder as well. Both happy and aggressive demeanors have been expressed in five different consumers at The Kennedy Center, a site which offers programs and services to individuals with varying disabilities. Research proposes several different genetic mechanisms responsible for the development of AS, each of which impact the function of the UBE3A gene located in the 15q11-13 region on chromosome 15. Additionally, from an evolutionary perspective, Emotion Signaling Theory and Kinship Theory have been used to provide another explanation for the observed behaviors of those possessing Angelman Syndrome.
Angelman syndrome (AS) is a rare neurodevelopmental disorder characterized by developmental delay, impaired communication, motor deficits and ataxia, intellectual disabilities, microcephaly, and seizures. The genetic cause of AS is the loss of expression of UBE3A (ubiquitin protein ligase E6-AP) in the brain, typically due to a deletion of the maternal 15q11-q13 region. Previous studies have been performed using a mouse model with a deletion of a single exon of Ube3a. Since three splice variants of Ube3a exist, this has led to a lack of consistent reports and the theory that perhaps not all mouse studies were assessing the effects of an absence of all functional UBE3A. Herein, we report the generation and functional characterization of a novel model of Angelman syndrome by deleting the entire Ube3a gene in the rat. We validated that this resulted in the first comprehensive gene deletion rodent model. Ultrasonic vocalizations from newborn Ube3am-/p+ were reduced in the maternal inherited deletion group
Angelman syndrome dominant or recessive - Is angelman syndrome dominant or recessive? Neither. Angelmans syndrome doesnt follow simple mendelian genetics. Rather, its due to de novo single genetic mutations, translocational errors, chromosomal abnormalities, or more commonly epi-genetic mutations such as changes in dna methylation.
Angelman syndrome (AS) is a severe neurodevelopmental disorder caused by mutation or deletion of the maternal UBE3A allele. The maternal UBE3A allele is expressed in nearly all neurons of the brain and spinal cord, whereas the paternal UBE3A allele is repressed by an extremely long antisense transcript (UBE3A-ATS). Little is known about expression of UBE3A in the peripheral nervous system, where loss of maternal UBE3A might contribute to AS phenotypes. Here we sought to examine maternal and paternal Ube3a expression in DRGs neurons and to evaluate whether nociceptive responses were affected in AS model mice (global deletion of maternal Ube3a allele; Ube3a(m-/p+ ...

Angelman Syndrome (AS) is a devastating neurological disorder caused by disruption of the maternal UBE3A gene. Ube3a protein is identified as an E3 ubiquitin ligase that shows neuron-specific imprinting. Despite extensive research evaluating the localization and basal expression profiles of Ube3a in mouse models, the molecular mechanisms whereby Ube3a deficiency results in AS are enigmatic. Using in vitro and in vivo systems we show dramatic changes in the expression of Ube3a following synaptic activation. In primary neuronal culture, neuronal depolarization was found to increase both nuclear and cytoplasmic Ube3a levels. Analogous up-regulation in maternal and paternal Ube3a expression was observed in Ube3a-YFP reporter mice following fear conditioning. Absence of Ube3a led to deficits in the activity-dependent increases in ERK1/2 phosphorylation, which may contribute to reported deficits in synaptic plasticity and cognitive function in AS mice. Taken together, our findings provide novel ...

The severity of the symptoms associated with Angelman syndrome varies significantly across the population of those affected. Some speech and a greater degree of self-care are possible among the least profoundly affected. Walking and the use of simple sign language may be beyond the reach of the more profoundly affected. Early and continued participation in physical, occupational (related to the development of fine-motor control skills), and communication (speech) therapies are believed to significantly improve the prognosis (in the areas of cognition and communication) of individuals affected by AS. Further, the specific genetic mechanism underlying the condition is thought to correlate to the general prognosis of the affected person. On one end of the spectrum, a mutation to the UBE3A gene is thought to correlate to the least affected, whereas larger deletions on chromosome 15 are thought to correspond to the most affected. The clinical features of Angelman syndrome alter with age. As adulthood ...

Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are two distinct disorders caused by imprinting defects in the chromosome 15q11.2-q13 region. Unaffected individuals have one methylated allele (maternal) and one unmethylated allele (paternal).. Prader-Willi syndrome (PWS) is caused by absence of the paternal (unmethylated) allele at chromosome locus 15q11.2-q13, which causes a constellation of physical and cognitive findings. The absence of the paternal allele can be caused by a number of genetic mechanisms.. Prader-Willi syndrome occurs with a frequency of 1 in 10,000 to 1 in 30,00 births and is characterized by specific facial features (almond shaped palpebral fissures, narrowed bi-frontal diameter), significant hypotonia during infancy, and hypogonadism. Hypotonia in affected children typically improves by 2 to 3 years of age, however by early childhood most affected individuals exhibit central obesity due to hyperphagia and global developmental delay.. Angelman syndrome (AS) is a ...

The characteristic phenotype of AS is severe mental retardation, ataxic gait, tremulousness, and jerky movements. We studied the movement disorder in 11 As patients, aged 3 to 28 years. Two patients had paternal uniparental disomy for chromosome 15, 8 had a , 3 Mb deletion, and 1 had a microdeletion involving loci D15S10, D15S113, and GABRB3. All patients exhibited quasicontinuous rhythmic myoclonus mainly involving hands and face, accompanied by rhythmic 5- to 10-Hz ...

Minocycline, a member of the tetracycline family, has a low risk of adverse effects and an ability to improve behavioral performance in humans with cognitive disruption. We performed a single-arm open-label trial in which 25 children diagnosed with Angelman syndrome (AS) were administered minocycline to assess the safety and tolerability of minocycline in this patient population and determine the drugs effect on the cognitive and behavioral manifestations of the disorder. Participants, age 4-12 years old, were randomly selected from a pool of previously screened children for participation in this study. Each child received 3 milligrams of minocycline per kilogram of body weight per day for 8 weeks. Participants were assessed during 3 study visits: baseline, after 8-weeks of minocycline treatment and after an 8-week wash out period. The primary outcome measure was the Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III). Secondary outcome measures included the Clinical Global
Results of a new study from the University of North Carolina at Chapel Hill may help pave the way to a treatment for a neurogenetic disorder often misdiagnosed as cerebral palsy or autism.
Abstract: Abstract Background The inability to analyze gene expression in living neurons from Angelman (AS) and Duplication 15q (Dup15q) syndrome subjects has limited our understanding of these disorders at the molecular level. Method Here, we use dental pulp stem cells (DPSC) from AS deletion, 15q Duplication, and neurotypical control subjects for whole transcriptome analysis. We identified 20 genes unique to AS neurons, 120 genes unique to 15q duplication, and 3 shared transcripts that were differentially expressed in DPSC neurons vs controls. Results Copy number correlated with gene expression for most genes across the 15q11.2-q13.1 critical region. Two thirds of the genes differentially expressed in 15q duplication neurons were downregulated compared to controls including several transcription factors, while in AS differential expression was restricted primarily to the 15q region. Here, we show significant downregulation of the transcription factors FOXO1 and HAND2 in neurons from 15q ...
Angelman syndrome (AS) is a neurodevelopmental disorder in which epilepsy is common (~90%) and often refractory to antiepileptics. AS is caused by mutation of the maternal allele encoding the ubiquitin protein ligase E3A (UBE3A), but it is unclear how this genetic insult confers vulnerability to seizure development and progression (i.e., epileptogenesis). Here, we implemented the flurothyl kindling and retest paradigm in AS model mice to assess epileptogenesis and to gain mechanistic insights owed to loss of maternal Ube3a. AS model mice kindled similarly to wild-type mice, but they displayed a markedly increased sensitivity to flurothyl-, kainic acid-, and hyperthermia-induced seizures measured a month later during retest. Pathological characterization revealed enhanced deposition of perineuronal nets in the dentate gyrus of the hippocampus of AS mice in the absence of overt neuronal loss or mossy fiber sprouting. This pro-epileptogenic phenotype resulted from Ube3a deletion in GABAergic but ...

New research by scientists at the University of North Carolina School of Medicine may have pinpointed an underlying cause of the seizures that affect 90 percent of people with Angelman syndrome (AS), a neurodevelopmental disorder.. Published online Wednesday, June 6, 2012 in the journal Neuron, researchers led by Benjamin D. Philpot, PhD, professor of cell and molecular physiology at UNC, describe how seizures in individuals with AS could be linked to an imbalance in the activity of specific types of brain cells.. Our study indicates that a common abnormality that may apply to many neurodevelopmental disorders is an imbalance between neuronal excitation and inhibition, Philpot said. This imbalance has been observed in several genetic disordersincluding Fragile X and Rett syndromes, both of these, like AS, can be associated with autism.. Angelman syndrome occurs in one in 15,000 live births. The syndrome often is misdiagnosed as cerebral palsy or autism. Its characteristics, along with ...

Features of patients with SLC9A6 mutations include mental retardation, microcephaly, truncal ataxia, grand mal epilepsy and lack of speech[OMIM #300243]. The clinical features of these patients suggest a similarity to Angelman syndrome, with developmental delay, ataxia, flexed arms, excessive drooling, happy demeanor with spontaneous smiling and laughter, as well as progressive microcephaly by two years of age. Most patients are found to have a slender body habitus, which differs from Angelman syndrome, where patients tend to become obese with age. Mutations in SLC9A6 are inherited in an X-linked pattern and result in clinical features in affected males and occasionally some mild features in carrier females. Deletions and/or duplications of the SLC9A6 gene as causative of X-linked Angelman-like syndrome have been reported. ...
Pitt-Hopkins syndrome (PTHS) is a genetic neurodevelopmental disorder associated with intellectual disability. Although the genetic mechanisms underlying the disorder have been identified, description of its behavioural phenotype is in its infancy. In this study, reported behavioural and psychological characteristics of individuals with PTHS were investigated in comparison with the reported behaviour of age-matched individuals with Angelman syndrome (AS) and Cornelia de Lange syndrome (CdLS). Questionnaire data were collected from parents/caregivers of individuals with PTHS (n = 24), assessing behaviours associated with autism spectrum disorder (ASD), sociability, mood, repetitive behaviour, sensory processing, challenging behaviours and overactivity and impulsivity. For most measures, data were compared to data for people with AS (n = 24) and CdLS (n = 24) individually matched by adaptive ability, age and sex. Individuals with PTHS evidenced significantly higher levels of difficulties with social

Angelman syndrome (AS) is a severe neurodevelopmental disorder lacking effective therapies. AS is caused by mutations in ubiquitin protein ligase E3A (UBE3A), which is genomically imprinted such that only the maternally inherited copy is expressed in neurons. We previously demonstrated that topoisomerase I (Top1) inhibitors could successfully reactivate the dormant paternal allele of Ube3a in neurons of a mouse model of AS. We also previously showed that one such Top1 inhibitor, topotecan, could unsilence paternal UBE3A in induced pluripotent stem cell-derived neurons from individuals with AS. Although topotecan has been well-studied and is FDA-approved for cancer therapy, its limited CNS bioavailability will likely restrict the therapeutic use of topotecan in AS. The goal of this study was to identify additional Top1 inhibitors with similar efficacy as topotecan, with the expectation that these could be tested in the future for safety and CNS bioavailability to assess their potential as AS therapeutics
I am sorry to say that your parents may have misunderstood the genetic explaination of the disease. A recessive allele never takes over a dominant allele. Cerebral Palsy, however, is mostly caused by infection, stroke (due to many rasons, such as abnormal blood cells),oxygen loss during pregnancy or child birth, jaundice, and Rh incompatibility. Thus Cerebral palsy seems to have no direct genetic component, however there can be an indirect genetic component such as the abnormal blood cells mentioned above. To talk about Anglemens Syndrome: Genetic imprinting- Differential modification of the expression of genes depending upon whether they are inherited from the mother or the father. This affects only certain segments of the human genetic complement,including PWS (Prader-willi Syndrome, see below) and Angelman syndrome on chromosome 15q. Anglemens Syndrome- A rare syndrome reported in 1965 by Dr. H. Angelman and associated with a chromosome 15 deletion similar to that seen in PWS. In AS, ...
Angelman syndrome (AS) is a neurodevelopmental disorder caused by the loss of function of the maternal UBE3A gene. The hippocampus is one of the most prominently affected brain regions in AS model mice, manifesting in severe hippocampal-dependent memory and plasticity deficits. Previous studies in AS mice reported an elongated axon initial segment (AIS) in pyramidal neurons (PNs) of the hippocampal CA1 region. These were the first reports in mammals to show AIS elongation in vivo. Correspondingly, this AIS elongation was linked to enhanced expression of the α1 subunit of Na+/K+-ATPase (α1-NaKA). Recently, it was shown that selective pharmacological inhibition of α1-NaKA by marinobufagenin (MBG) in adult AS mice rescued the hippocampal-dependent deficits via normalizing their compromised activity-dependent calcium (Ca+2) dynamics. In the herein study, we showed that a chronic selective α1-NaKA inhibition reversed the AIS elongation in hippocampal CA1 PNs of adult AS mice, and differentially altered

Rett syndrome is a neurodevelopmental disorder that is classified as an autism spectrum disorder by the DSM-IV. It was first described by Austrian pediatrician Andreas Rett in 1966. The clinical features include a deceleration of the rate of head growth (including microcephaly in some) and small hands and feet. Stereotypic, repetitive hand movements such as mouthing or wringing are also noted. Girls with Rett syndrome are prone to gastrointestinal disorders and up to 80% have seizures. They typically have no verbal skills, and about 50% of females are not ambulatory. Scoliosis, growth failure, and constipation are very common and can be problematic. Some argue[citation needed] that it is misclassified as an autism spectrum disorder, just as it would be to include such disorders as fragile X syndrome, tuberous sclerosis, or Down syndrome where one can see autistic features. The signs of this disorder are most easily confused with those of Angelman syndrome, cerebral palsy and autism ...
IVF linked to rare genetic disorders. Dr. Weksberg who is a geneticist at the University of Toronto, has called for more study of the link between fertility treatment and certain rare genetic abnormalities. She notes that babies, who are born after this treatment, are 10 times more likely to suffer from these disorders. These babies also have an increased likelihood to be born at a low birth weight, and there is conflicting research suggesting an increased risk of autism. She says that in her genetic clinic, she is seeing many people who were conceived through fertility treatment and who have one of the conditions.. For example, Beckwith-Wiedemann syndrome can cause unevenly sized limbs, an enlarger tongue, and a high risk of kidney tumors. It occurs in one of every 13,000 children in the general population, but at a much higher rate of one in 1,300 in children conceived through IVF. Similarly, Angelman syndrome which causes serious mental retardation and speech impairment, increases from one in ...

Most researchers believe that certain genes a child inherits from their parents could make them more vulnerable to developing ASD.. Cases of ASD have been known to run in families. For example, younger siblings of children with ASD can also develop the condition, and its common for identical twins to both develop ASD.. No specific genes linked to ASD have been identified, but it may be a presenting feature of some rare genetic syndromes, including Fragile X syndrome, Williams syndrome and Angelman syndrome.. ...
The day after, ready to go home!. We still hadnt heard much from Childrens about the genetic testing throughout the few months after Rheyn was born. Since their first suggestion of an abnormal 15th chromosome they determined that wasnt the case but didnt have much else to tell us. Then during the first week of October I got a call from the genetics department telling me that they finally had some answers and would like for us to come in so that we could talk in person. So on October 16th, 2008 when Rheyn was 10 months old, we made the three hour drive to Childrens and met with the geneticist and two other doctors on his team that had been studying Rheyns case. First they told Dan and me that they thought Rheyn had Angelman Syndrome or Prader Willi Syndrome but his constant, strong movement in the womb and his far-less-than lethargic lifestyle even after birth didnt match up with either of those. They told us that once they dug deeper with micro-something-or-other they finally found that ...
Calcium and ion channels play a critical role in neuronal signaling. T-type calcium channels (Cav3.1, 3.2, & 3.3) respond to small membrane depolarizations and gate the activity of additional ion channels whose activation results in the firing of neurons. Cav3s finely-tuned voltage-gated property and pacemaker function mediates the transition from tonic to bust-firing and generates neural oscillations between brain nuclei and across their pathways.. The transition to burst-firing and abnormal oscillatory pattern occurs in a number of neurologic disorders, including essential tremor, Parkinsons disease, dystonia, epilepsy, pain, and schizophrenia and rare, pediatric genetic disorders, such as Angelman Syndrome. These diseases are mediated by Cav3, a common pathophysiologic pathway. Central and peripheral biomarkers facilitate in vivo readouts of dysrhythmia s and target modulation with Cavions Cav3 therapies.. Despite substantial interest in Cav3 as a target, to date there has been little ...

[...] the 3½-year-old doesnt even need a key for the ignition, thanks to a collaboration between Central Connecticut State University and students from three New Haven schools. Nicholas, who has Angelman syndrome, was one of seven children under the age of 5 with mobility disabilities receiving robot-controlled ride-on cars at Celentano Biotech, Health and Medical Magnet School Friday afternoon. According to Michele Dischino, an associate professor at CCSU who coordinates the GoBabyGo! program for the universitys CCSU Collaboration for Assistive Resources, Equipment and Services (CCSU C.A.R.E.S.) club, wheelchairs that can securely fit young children do not often exist, so the ride-on cars offer children mobility they would not otherwise have. According to Dischino, CCSU C.A.R.E.S. brought the program to the New Haven area after hosting it in four other in-state locations since April.
