The disease Angelman Syndrome, named after the physician Harry Angelman, was first diagnosed in 1965. It is now known that the disease results from the loss of function of UBE3A, a gene. One is normally inherited from each parent. The copy inherited from the mother is active in certain areas of the brain. If this copy of the gene UBE3A is lost due to chromosomal change or gene mutation, the lost gene will not have active copies in parts of the brain. A majority (70%) of Angelman syndrome cases happen when a segment of the maternal chromosome 15 is lost or destroyed. A minority of the disease is caused by a mutation or loss of function of the mother’s copy of the UBE3A gene. The majority of cases result from uniparental disomy, which is when the son or daughter inherits two copies of chromosome 15 from his or her father. Translocation, or chromosomal rearrangement, can also cause the disease. Most cases of this disease are not inherited, instead are a result of deletion in the maternal chromosome 15.

Marfan syndrome is an inherited disorder that affects the connective tissue of the body (“What is Marfan Syndrome?” n.d.). The connective tissue plays a vital role in supported the tendons, heart valves, cartilage, blood vessels, and more parts of the body (“Connective Tissue,” n.d.). “What is Marfan Syndrome?” (n.d.) explains that the condition has no cure, and those who have it lack strength in their connective tissue, affecting their bone, eyes, skin, nervous system, and lungs. Furthermore, Marfan syndrome is common, and it is imperative to understand how the body is affected by it, the symptoms, and the treatment of this condition.

It is characterized by normal early growth and development followed by a slowing of development, the loss of purposeful use of the hands, slowed brain and head growth, problems with walking, seizures, and intellectual disability.
Ivy is the third generation in her family to be affected by achondroplasia. Her grandfather, her father, and her brother also have it. Achondroplasia is inherited as an autosomal dominant trait whereby only a single copy of the abnormal gene is required to cause achondroplasia. Nobody with the mutated gene can escape having achondroplasia. Many individuals with achondroplasia have normal parents, though. In this case, the genetic disorder would be caused by a de novo gene mutation. De novo gene mutations are associated with advanced paternal age, often defined as over age 35 years. If an individual with achondroplasia produce offspring with a normal individual, the chances of the offspring inheriting the mutant allele achondroplasia is 50%. If both of the parents have achondroplasia, the chances that their offspring will be of normal stature a...
However, in a person with PWS, the 15th chromosome has been given 2 genes from the mother, and none from the father. This is called maternal UPD ( uni-parent disomy) in which 2 copies of the maternal chromosome are inherited with no paternal contribution. Despite the presence of 2 intact chromosomes, there is a functional abnormality in the imprinting that may lead to the absence of gene expression from the paternally donated chromosome, resulting in the PWS phenotype (physical trait) that is common in persons with PWS.

Angelman Syndrome is a neuro-genetic disorder, brought upon the body through the mutilation or deletion of the maternal 15th chromosome. The prevalence of this disorder is still constantly debated because of the common symptoms it shares with other disorders, making it difficult to recognize and differentiate. More specific studies of behavior are needed to increase the range of knowledge on such a complex disorder. In 2007 Dr. Weeber relieved a mouse model of many symptoms of Angelman Syndrome. Studies of this disease are crucial for finding the cure. Even though this is a difficult challenge, there are signs of hope to cure this disease for humans.
In the brain, the Angelman gene is primarily expressed from the maternally inherited chromosome 15. There are four known genetic mechanisms that cause Angelman syndrome. The most common way of getting Angelman syndrome is through chromosome deletion. This is responsible for about 68% of all cases of this syndrome. The chromosome deletion removes the area where 15q12 is found and its surrounding area.

Research of the disorder show that there is no clear inheritance ties to Dandy Walker Syndrome, however some family members will inherit the gene to cause the disorder. Very rarely does the syndrome spiral from family genetics, but rather a gene mutation or an copied chromosome. (Dandy-Walker Malformation) The said malformation of the cerebellum is a growth of the forth ventricle that is located on the spinal cord. On top of that, the vermis, a vital portion of the cerebellum, may be completely absent. Fortunately, subjects whom have Dandy-Walker Syndrome are not suffering from a catastrophic illness. A
Angelman Syndrome is a rare genetic disorder characterized by neurological and developmental issues. Dr. Harry Angelman discovered the syndrome in 1965. It was formerly called “Happy Puppet Syndrome” due to the clinical features possessed by those affected. Dr. Angelman observed those affected as appearing normal upon birth but eventually showing signs of development disabilities. Angelman Syndrome mainly targets the nervous system and can be detected in infants as early as six months. Typically, the first noticeable sign is usually feeding problems or a delay in development. It is caused by a deletion or mutation, such as translocation, in Chromosome 15, long arm q, band 12. Some references note the affected region as bands 11.2-13. This area encodes for the UBE3A gene. Usually, the body uses information from both copies of a gene. The activity of each gene copy is dependent on whether it was passed from your mother or from your father. This parent-specific gene activity is called imprinting. In a few instances, only one copy of a gene pair is active. For the UBE3A gene, only the maternal copy is active in the brain. This is an example of genomic imprinting in which the body only recognizes or requires one copy to be active. In Angelman Syndrome, the body only recognizes the maternal copy of chromosome 15. However, there have been a few rare incidences in which uniparental disomy was the cause of acquiring the syndrome. This occurs when both copies of chromosome 15 were inherited from the paternal side.
Angelman Syndrome (AS) is a neurodevelopmental disorder, which is caused by mutations or deletions of the UBE3A gene inherited from the maternal allele. This gene encodes the protein E3 ubiquitin ligase. UBE3A is expressed biallelically in majority of tissues but in most neurons the maternal allele is solely expressed. In 1965 Dr. Harry Angelman an English pediatrician first described Angelman syndrome. At the time of discovery Dr. Angelman named the disorder “happy puppet syndrome” this was due to a puppet-like ataxic movement he observed in children inflicted. In the publication in which he first described AS, he stated there were certain features that he viewed in all children with the disorder. The features that Angelman stated the children
This disorder is caused by changes in the DNA of cells that make hemoglobin, the substance in human red blood cells that carries oxygen throughout your entire body. This disease is a inheritance disorder passed from parents to children. When parents have low count of hemoglobin and high could of red blood cell it is then transferred to their new born child.
There is no specific treatment for down syndrome. A child born with a gastrointestinal blockage may need major surgery immediately after birth. Or a Certain heart defect may require surgery depending on how serious it is. Obesity can be a problem in older kids or adults so they need to keep active but before they do so they have to get their hips and neck examined. Behavioral discipline can help people with Down syndrome and their families deal with the frustration, anger, and compulsive behavior that will occur. Parents should learn to help a person with Down syndrome deal with frustration and anger. Although, it is important to encourage independence.
