Down syndrome (MIM 190685) is the most common genetic form of mental retardation. It is caused by trisomy of all or a portion of chromosome 21. The 2.5-Mb region [3, 4] between DNA markers D21S17 and ERG (MIM 165080) is associated with the main features of Down syndrome and is termed the Down syndrome critical region. As part of the human genome project, our laboratory is studying the physical structure of human chromosome 21. To identify the genes and functional units mapped on chromosome 21, we are focusing on the physical mapping and sequencing of several regions. One region we have sequenced is the distal 1.6-Mb end of the Down syndrome critical region. The 4-Mb region from the SOD1 gene (MIM 147450) to the AML1 (MIM 151385) gene will soon be completely sequenced. This study describes the detailed sequence analysis of these two regions of chromosome 21.
Down syndrome (DS) is characterized by structural and functional anomalies that are present prenatally and that lead to intellectual disabilities. Later in life, the cognitive abilities of DS individuals progressively deteriorate due to the development of Alzheimers disease (AD)-associated neuropathology (i.e., ?-amyloid (A?) plaques, neurofibrillary tangles (NFTs), neurodegeneration, synaptic pathology, neuroinflammation and increased oxidative stress). Increasing evidence has shown that among these pathological processes, neuroinflammation plays a predominant role in AD etiopathology. In AD mouse models, increased neuroinflammation appears earlier than A? plaques and NFTs, and in DS and AD models, neuroinflammation exacerbates the levels of soluble and insoluble A? species, favoring neurodegeneration. The Ts65Dn (TS) mouse, the most commonly used murine model of DS, recapitulates many alterations present in both DS and AD individuals, including enhanced neuroinflammation. In this study, we ...

This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. This gene is excluded as a candidate for a form of nonsyndromic deafness (DFNB10), but is still a candidate for other disorders mapped to 21q22.3 as well as for the development of Down syndrome phenotypes. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, May 2012] ...

DOPEY2 is a human gene located just above the Down Syndrome chromosomal region (DSCR) located at 21p22.2 sub-band. Although the exact function of the this gene is not yet fully understood, it has been proven to play a role in multiple biological processes, and its over-expression (triplication) has been linked to multiple facets of the Down Syndrome phenotype, most notably mental retardation. The DOPEY2 gene is located on human chromosome 21, at chromosome band 21q22.12. This band is located in open reading frame 5, hence the alias C21orf5. DOPEY2 gene is composed of 137,493 bases making up 37 exons and 39 distinct gt-ag introns, all located between CBR3 and KIAA0136 genes. Transcription produces 10 unique mRNAs, 8 alternatively spliced variants, and 2 unspliced forms. These unique mRNAs differ by varying truncation of the 3 and 5 ends, as well as the presence of 3 cassette exons. These mRNA variants range from 7691bp (mRNA variant DOPEY2.aAug10) to 315bp (mRNA variant DOPEY2.jAug10-unspliced) ...
Periodontal disease (PD) is characterized as an inflammatory process that compromises the support and protection of the periodontium. Patients with Downs syndrome (DS) are prone to develop PD. Neutrophils (NE) are the first line of defense against infection and their absence sets the stage for disease. Aim: To compare the activity and function of NE in the peripheral blood from DS patients with and without PD, assisted at the Center for Dental Assistance to Patients with Special Needs affiliated with the School of Dentistry of Araçatuba, Brazil. Methods: Purified NE were collected from peripheral blood of 22 DS patients. NE were used to detect the 5-lypoxigenase (5-LO) expression by RT-PCR. Plasma from peripheral blood was collected to measure tumor necrosis factor-a (TNF-α) and interleukin-8 (IL-8) by ELISA and nitrite (NO3) using a Griess assay. Results: Data analysis demonstrated that DS patients with PD present high levels of TNF-a and IL-8 when compared with DS patients without PD. ...
Results Thirty-one centres and 1158 patients were included in the first stage of the study. Overall prevalence of known CHD was 16% (189 defects). Screening was performed in 138 patients without known CHD. In total, 24 new patients (17%) with a CHD were found, of which six patients needed semi-urgent care. Furthermore, 77% of the screened patients had mild to moderate regurgitation in one or more heart valves. Overall prevalence of CHD in adult Downs syndrome patients living in residential centres would be estimated at 33%. ...

Down syndrome occurs in people of all races and economic levels, though older women have an increased chance of having a child with Down syndrome. A 35 year old woman has about a one in 350 chance of conceiving a child with Down syndrome, and this chance increases gradually to 1 in 100 by age 40. At age 45 the incidence becomes approximately 1 in 30. The age of the mother does not seem to be linked to the risk of translocation. ...

An infant is reported who presented with a de novo 21;21 translocation trisomy 21 and an atypical phenotype for Down syndrome (DS). Findings included microcephaly, small stature, downslanting palpebral fissures, absent Brushfield spots, moderate micrognathia, left ptosis, left torticollis, severe developmental delay, seizures, and hypertonia. Further clinical evaluation using both the diagnostic criteria for DS and the Jackson checklist of 25 signs was inconsistent with the diagnosis for DS. Blood karyotype revealed: 46,XX,+21,dic(21;21) (p11.2;p11.2). Fluorescence in situ hybridization (FISH) analysis confirmed the trisomy 21 translocation. Both parents had normal karyotypes. Chromosome and FISH analyses were performed on skin fibroblasts. These studies revealed mosaicism for a translocation trisomy 21 cell line as wel as a second cell line consisting of one normal chromosome 21 and a ring chromosome 21 derived from translocation 21q21q which appeared to have a deletion of the critical region for DS

Down syndrome may be understood best as a syndrome complex of genetic and epigenetic origin with several characteristic neurodevelopmental manifestations. DS is a chromosomal disorder. Majority of cases result from complete trisomy of chromosome 21 due to nondisjunction during meiosis. A region on chromosome 21 proximal to 21q22.3, known as down syndrome critical region, is considered responsible for pathogenesis of DS. In approximately 95% of cases of trisomy 21, the nondisjunction is of maternal origin; which occurs "randomly" during meiosis. Rarely, in about 1% of cases, nondisjunction may occur after fertilization is complete, resulting in two different cell lines, and this is referred to as mosaicism. Approximately 4% of the time, DS results from complete or partial translocation of chromosome 21 to another chromosome. This so called Robertsonian translocations occurs when the long arms of two acrocentric chromosomes fuse at the centromere. The two short arms get lost as a result. Although ...
Robertsonian translocations (RBT) are associated with an increased risk of aneuploidy. Single RBT carriers are the most common balanced rearrangement among the carrier couples with the history of spontaneous abortion. However, double Robertsonian translocations (DRBT), in which two balanced RBT occur simultaneously, are an extremely rare condition. A 9-year-old mentally normal ...
Usually each egg and sperm cell contains 23 chromosomes (half the normal number). The union of these cells creates 23 matched pairs, or 46 total chromosomes at the time of fertilization. In this manner, a person receives exactly half of their genetic material from each biological parent. Sometimes, an error occurs when an egg or sperm cell is forming, causing it to have an extra chromosome #18 or #13 inside. If this cell contributes that extra chromosome 18 to the embryo, then trisomy 18 results. If this cell contributes that extra chromosome 13 to the embryo, then trisomy 13 results. The extra chromosome 18 or 13 can come from either the mothers egg cell or the fathers sperm cell. The features of trisomy 18 and trisomy 13 result from having this extra copy of chromosome 18 or 13 in each of the bodys cells.. Occasionally, the extra chromosome 18 or 13 is attached to another chromosome in the egg or sperm; this is called a translocation. This is the only form of trisomy 18 or 13 that can be ...
Down syndrome is the genetic condition resulting when a baby is born with three, rather than the usual two, copies of chromosome 21. Because there are three copies of chromosome 21, Down syndrome is also called Trisomy 21. Instead of 46 chromosomes, a person with Trisomy 21 has 47. This extra genetic material affects the cognition and development of the child, but is not a blueprint that determines his or her potential, success or inability to lead a fulfilling, meaningful life.. One in every 691 babies in the United States is born with Down syndrome, making Down syndrome the most common genetic condition. Approximately 400,000 Americans have Down syndrome and about 6,000 babies with Down syndrome are born in the United States each year.. Down syndrome occurs in people of all races and economic levels, though older women have an increased chance of having a child with Down syndrome. A 35 year old woman has about a one in 350 chance of conceiving a child with Down syndrome, and this chance ...

Well tell you what you can do if you have or suspect you have this translocation.
In addition, the team identified the gene fragment in mice that is largely responsible for LC degeneration - a region of about 32 genes including APP 23, 24. In a knockout mouse model with the third copy of APP deleted, the decrease in LC neurons did not occur, suggesting that App over-expression is necessary for LC degeneration. However, deleting the extra copy did not restore normal contextual learning behavior.. "Simply deleting the third App doesnt fix the behavior, so probably other gene products play a role in Downs syndrome," said Mobley. "However, giving the pro-drug to the mice rescued cognitive behaviors in a very dramatic way." He noted that a form of this drug is currently in clinical trials to treat fibromyalgia in humans. "The possibility is very real that such a therapy, if proven safe, would be effective in treating dementia in later-stage Downs syndrome patients.". Additional contributors include Paul Aisen and Steven L. Wagner, UC San Diego Department of Neurosciences; and ...

The Global Down Syndrome Educational Series was launched in 2006 and brings nationally and internationally renowned Down syndrome experts to Colorado for two full days of lectures. The first day is designed for professionals who impact the lives of individuals who have Down syndrome, and the second is for parents and caregivers. Topics focus on accurate and updated medical, educational, and therapeutic best practices.. There are two driving forces behind the Global Down Syndrome Foundations Educational Series: (1) the desire to provide training to professionals since surveys show that many professionals (doctors, therapists and such) are not trained to provide the best care to a person with Down syndrome, and (2) the desire to provide parents and caregivers who are not able to attend the National Down Syndrome Congress Annual Convention, a taste of what it is like to have a renowned Down syndrome expert provide a full day of useful information and answer a multitude of questions.. ...
In order to ensure the best medical care for their granddaughter, the family searched for the best local doctor who would ideally have dozens - if not more - children with Down syndrome in their practice. There were no such local experts, and the Sies began to wonder how families with limited resources or education were able to find good quality health care for their children with Down syndrome.. Because of additional medical issues, the family also experienced medical specialists who used antiquated language and who had outdated stereotypes about people with Down syndrome that they concluded were dangerous (e.g. people with Down syndrome dont feel pain, people with Down syndrome cannot evolve past a preschool level).. In addition, although they were receiving interventions and therapies from the state from local experts, it was only after spending time with a Anna and John J. Sie Foundation, to investigate the area of medical care for people with Down syndrome.. The results of the ...
