Definition of robertsonian translocation in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is robertsonian translocation? Meaning of robertsonian translocation as a legal term. What does robertsonian translocation mean in law?
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 ...
A Robertsonian translocation is a chromosomal abnormality that generally doesnt cause health problems. However, it can affect pregnancy, especially when it results in a fetus with a genetic condition that is incompatible with life. Well tell you what you can do if you have or suspect you have this translocation.

Hi there, I am researching chromosome 2 fusion theory. The theory that chromosome 2 and 3 was fused by a Robertsonian Translocation in two human-chimp common ancestors which mated giving us our chromosome 2 and 46 chromosomes instead of the other higher primates 48.. I was attempting to understand what the odds of this occurring were, to which end I want to know the odds that a chimp baby will be born with this mutation. I understand that 1 in 1000 human babies are born with a Robertsonian Translocation, is it the same for chimps?. ...

Translocation is the exchange of chromosome segments, usually between nonhomologous chromosomes. There are two primary types of translocations: reciprocal translocations and Robertsonian translocations. A reciprocal translocation occurs when segments from nonhomologous chromosomes break off, with segment attaching to the other chromosome and vice-versa. A Robertsonian translocation occurs when two acrocentric chromosomes (chromosomes with tiny short arms, meaning the centromere is near one end) fuse at the centromere and lose their short arms.. Reciprocal translocations usually involve only two chromosomes, meaning the total chromosome number is unchanged. Reciprocal translocation are typically harmless, despite being more common in individuals so retarded that they require institutional care. There are three kinds of reciprocal translocation: alternate; adjacent-1; and adjacent-2.. Robertsonian translocations lead to a balanced karyotype with only 45 chromosomes. Because acrocentric short arms ...
Robertsonian translocation: Two breaks occur in separate chromosomes, usually the 14th and 21st chromosomes. There is rearrangement of the genetic material so that some of the 14th chromosome is replaced by extra 21st chromosome. So while the number of chromosomes remain normal, there is a triplication of the 21st chromosome material ...

Since publication of the classic descriptions by Riopelle and ThÉRiault (1956) and Enzinger and Shiraki (1969) the morphology of alveolar rhabdomyosarcoma (aRMS) has been well known. RMS presenting with clear and unequivocal (pseudo)alveolar spaces can be recognized at first sight as the alveolar (sub-)type of RMS. On the other hand, a diagnosis of aRMS may be difficult in cases which display neither significant evidence of rhabdomyogenesis in conventionally stained slides nor unambiguous alveolar spaces. In such cases the diagnosis of RMS must be confirmed by special staining including immunohistochemistry. ...
Trisomy 18 and 13 What are trisomies? The term trisomy is used to describe the presence of three chromosomes, rather than the usual pair of chromosomes. For example, if a baby is born with three #21 chromosomes, rather than the usual pair, the baby would be said to have trisomy 21. Trisomy 21 is also known as Down syndrome. Other examples of trisomy include trisomy 18 and trisomy 13. Again, trisomy 18 or trisomy 13 simply means there are three copies of the #18 chromosome (or of the #13 chromosome) pr...

Introduction: Rhabdomyosarcoma is an uncommon tumor seen in young adolescents and adults that metastasizes to the peritoneum. Case Report: Here we report a case of 18-year-old female who had alveolar rhabdomyosarcoma of nose and was treated with chemoradiotherapy. After one year, she presented with ascites. Ascitic fluid cytology revealed deposits of rhabdomyosarcoma. Immunohistochemistry done to support the diagnosis. This case report highlights the cytological features of rhabdomyosarcoma cells, which were large pleomorphic with high nuclear cytoplasmic ratio, coarse chromatin and scant cytoplasm. A small population of cells was almost the size of mesothelial cells, which could be mistaken for a reactive mesothelial cells. Conclusion: Awareness of rare metastases of rhabdomyosarcoma in peritoneum and recognition of the cytological features of these malignant cells supported by specific immunostains helps in the diagnosis.

Alternative splicing was the first phenomenon scientists discovered that made them realize that genomic complexity cannot be judged by the number of protein-coding genes. During alternative splicing, which occurs after transcription and before translation, introns are removed and exons are spliced together to make an mRNA molecule. However, the exons are not necessarily all spliced back together in the same way. Thus, a single gene, or transcription unit, can code for multiple proteins or other gene products, depending on how the exons are spliced back together. In fact, scientists have estimated that there may be as many as 500,000 or more different human proteins, all coded by a mere 20,000 protein-coding genes. ...

Rhabdomyosarcoma is the most common soft tissue sarcoma of childhood. Especially the alveolar rhabdomyosarcoma (ARMS) shows poor prognosis when metastases have developed. [...]
Researchers at Oregon Health & Science University Doernbecher Childrens Hospital have identified a promising new approach to overcoming drug resistance in children with an extremely aggressive childhood muscle cancer known as alveolar rhabdomyosarcoma. Their findings are published online this week in the journal Molecular Cancer Therapeutics and will be featured on the cover of the journals print edition next month.. Rhabdomyosarcoma accounts for more than 50 percent of all soft-tissue cancers in children. Even after extensive therapy, the survival rate among alveolar rhabdomyosarcoma patients with advanced disease is less than 20 percent. Dismal outcomes such as these are what keep researchers in the Pediatric Cancer Biology Program at OHSU Doernbecher working around the clock toward a breakthrough.. "Despite our best efforts, outcomes for metastatic alveolar rhabdomyosarcoma have not improved for decades. Thats why our findings are significant. Our clinical partners now have a new method of ...
It is believed that some rhabdomyosarcoma tumors begin developing in the fetus. Rhabdomyoblasts are the cells at the initial stages of development of an unborn baby. These cells will mature and develop into muscles. There has been much research into the gene structure of these rhabdomyoblasts and possible detection of a gene error that can produce the disease later in development.. Rhabdomyosarcomas usually have some type of chromosome abnormality in the cells of the tumor, which are responsible for the tumor formation. In children with an embryonal rhabdomyosarcoma, there is usually an abnormality of chromosome 11. In alveolar rhabdomyosarcoma, a rearrangement in the chromosome material between chromosomes 2 and 13 is usually present. This rearrangement changes the position and function of genes, causing a fusion of genes referred to as a fusion transcript. Patients have an abnormal fusion transcript involving two genes known as PAX3 and FKHR. This important discovery has led to improvements in ...
In 1974, Segal and McCoy reported that primary foreskin fibroblasts of trisomy 21 patients proliferate more slowly than euploid control cells ( 6). Similar results were obtained from studies of primary mouse cells ( 7) or human cell lines ( 8) with decreased chromosome segregation fidelity. We set out to characterize the effects of a single extra chromosome on cell growth and proliferation in a systematic manner. This approach not only enabled us to determine whether every chromosome when present in an extra copy interferes with proliferation, but also allowed us to determine whether a general response to aneuploidy exists.. We established MEFs trisomic for either chromosome 1, 13, 16, or 19 using mice with balanced Robertsonian translocations. Analysis of the cell lines established from these aneuploid embryos revealed that cell proliferation was hampered in all trisomic MEFs compared with euploid controls. Furthermore, the characterization of the trisomic MEFs revealed a number of shared ...

It is clear that, although we have learned much about the biology of MM, many questions remain. All of the available data suggest that IgH translocations are present in a majority (∼50-60%) of tumors, yet are not sufficient to exert the full malignant potential of the clone. Although early dysregulation of cyclin D1, D2, or D3 may represent a unifying event, it seems likely that two distinct pathways exist in the pathogenesis of MM. One pathway appears to involve an early IgH translocation that usually includes one of the four recurrent partners (11q13, 4p16, 16q23, 6p21), and mostly is associated with a nonhyperdiploid chromosome content. The second pathway infrequently, if ever, involves an early IgH translocation but mostly is associated with a hyperdiploid chromosome content, perhaps a reflection of intrinsic genetic instability, although we have virtually no understanding of this pathway. The timing and nature of additional genetic events that are involved in early pathogenesis is ...

The most common chromosomal abnormalities are trisomies - 3 copies of one of the chromosomes. The most common of these is trisomy 21, or Down syndrome.
The term translocation is used when the location of specific chromosome material changes. There are two main types of translocations: reciprocal and Robertsonian
