Down Syndrome

What a difference an extra chromosome can make. Here we explore the misconceptions -- as well as the ups and downs -- of Down Syndrome, a congenital genetic disorder that is caused by the presence of an extra 21st chromosome. The affected person is mildly to moderately handicapped, short in stature, and has a flattened facial profile.

Do Matthew and Joseph levinson have Down syndrome?

I don't have specific information about individuals named Matthew and Joseph Levinson, so I cannot confirm whether they have Down syndrome or not. Down syndrome is a genetic condition that affects individuals differently, and personal health information is typically private. If you have a general question about Down syndrome, feel free to ask!

What are some characteristics of children with Down syndrome?

Children with Down syndrome typically exhibit physical characteristics such as a flat facial profile, upward slanting eyes, and a single deep crease across the center of the palm. They may also have developmental delays, intellectual disabilities, and may experience health issues such as heart defects and respiratory problems. Additionally, children with Down syndrome often have a friendly and affectionate demeanor, with a tendency to be sociable and empathetic towards others.

Does ross kemp have Down syndrome?

No, Ross Kemp does not have Down syndrome. Down syndrome is a genetic condition caused by the presence of an extra chromosome 21. Ross Kemp is a British actor, author, and investigative journalist known for his roles in various television shows, and there is no public information or evidence to suggest that he has Down syndrome.

Is it common for a person with Down syndrome to marry someone who doesn't have Down syndrome?

Yes, it is possible and not uncommon for a person with Down syndrome to marry someone who does not have Down syndrome. Marriage is a personal choice that individuals make based on their feelings and compatibility with their partner, regardless of any disabilities. As long as both individuals are legally able to consent to marriage and understand the commitment they are making, there is no legal barrier to a marriage between a person with Down syndrome and someone without the condition.

What is marphans syndrome?

Marfan syndrome is a genetic disorder that affects the body's connective tissue, which provides support and structure to various tissues and organs. This condition is caused by mutations in the FBN1 gene, which encodes a protein called fibrillin-1. Individuals with Marfan syndrome may experience a range of symptoms, including tall stature, long limbs, joint hypermobility, and cardiovascular issues such as aortic aneurysms. Treatment typically focuses on managing symptoms and monitoring for potential complications.

What is head shape in down's syndrome?

Regardless of how serious the condition is, individuals with Down disorder have a generally perceived appearance. The head might be more modest than typical and strangely formed. For instance, the head might be round with a level region on the back. The inward corner of the eyes might be adjusted rather than pointed

What trisomy causes Down syndrome?

Well, honey, Down syndrome is caused by an extra copy of chromosome 21, also known as trisomy 21. It's like having a bonus chromosome that messes with the genetic party. So, to put it simply, trisomy 21 is the culprit behind Down syndrome.

How does a parent obtain legal guardianship of adult child with down syndrome disability?

To obtain legal guardianship of an adult child with Down syndrome or a disability, a parent must file a petition in court. The court will assess the child's ability to make decisions independently and determine if guardianship is necessary for their well-being. This process often requires medical evaluations and legal documentation. If granted, the parent will have the legal authority to make decisions on behalf of the adult child, including those related to healthcare, finances, and living arrangements. to know more discuss or take help Guardianship lawyer(561-444-0131).

What chromosomal mutation causes an extra copy of chromosome 13?

Trisomy 13, also known as Patau syndrome, is a chromosomal mutation where there is an extra copy of chromosome 13 in each cell. This condition can lead to various physical and intellectual disabilities.

Why do geneticists suspect that the extra chromosome seen in down syndrome usually comes from the egg rather than the sperm?

Geneticists suspect that the extra chromosome seen in Down syndrome usually comes from the egg rather than the sperm because women are born with all the eggs they will ever have, and the risk of an error during egg development increases with maternal age. Sperm, on the other hand, are constantly being produced, so the likelihood of an error leading to an extra chromosome is lower.

Trisomy 21 is a condition usually caused by?

Trisomy 21, also known as Down syndrome, is usually caused by the presence of an extra copy of chromosome 21 in every cell. This additional genetic material disrupts normal development and results in the characteristic features of Down syndrome, such as intellectual disability and distinctive facial features.

What evidence suggest that Down syndrome is more often the result of non-disjunction during oogenesis rather than during spermatogenesis?

One decent piece of evidence is that the incidence of newborns with Down's increases exponentially with the age of the mother. Once a woman reaches 45 years of age the chance of her having a child with Down's becomes 1:30, as opposed to 1:1667 if the woman is 20. No correlation like this has been found in the age of the father.

The increase in the incidence of Down's with mothers age is likely because all of the eggs a female has are with her from birth. They are trapped in one of the stages of the cell cycle (prophase 1 of meiosis). The longer the woman waits before becoming pregnant the older of an egg cell she is using. These older cells have been trapped in prophase 1 for many years. This, in some way, leads to an increase in the rate of non-dysjunction events (failure of 2 chromosomes to separate) and thus, an increase in trisomy 21.

How do you detect if you have down syndrome?

Autosomal means that it concerns an autosome--a chromosome other than a sex chromosome.

Down syndrome is caused by an additional copy of the 21st chromosome. Since the 21st chromosome is not a sex chromosome, Down syndrome is autosomal.

Is a short Femur a sign of Down Syndrome?

A short femur can be a soft marker for Down Syndrome when detected during prenatal ultrasound screening, but it is not a definitive diagnosis. Down Syndrome is typically confirmed through genetic testing. Short femur measurements alone are not enough to diagnose Down Syndrome. It is important to consult with a healthcare provider for further evaluation and testing.

Is there any connection between Down syndrome and fear of dogs?

There is no direct connection between Down syndrome and a fear of dogs. Fear of dogs, known as cynophobia, can develop in any individual regardless of their health condition. It is important to approach individuals with Down syndrome, like anyone else, with patience, understanding, and respect when it comes to their feelings and fears.

How were people with Down's Syndrome treated by the ancient Maya?

when we were down in uxmal Mexico in January, a local there told us that down synrome people were highly regarded by the mayans. It is said that they would put special, elect people to watch over them.

How likely at the age of twenty-three are you to have a baby born with down syndrome?

The likelihood of having a baby with Down syndrome increases with maternal age, with the risk increasing after the age of 35. At the age of 23, the probability of having a baby with Down syndrome is very low compared to older ages, but there is still a small risk. Prenatal screening tests can provide more information about the specific risk based on individual circumstances.

What are the physical and the mental and the behavioral abnormalities in someone who has Down syndrome?

Physical abnormalities in Down syndrome can include low muscle tone, small stature, and distinct facial features. Mental abnormalities may manifest as intellectual disability and delays in cognitive development. Behavioural abnormalities can vary but may include impulsivity, stubbornness, and difficulties with language and communication.

If you have a brother or a sister with Down syndrome does this increase the chances of giving birth to a child with Down syndrome?

Having a sibling with Down syndrome does not directly increase the chances of giving birth to a child with Down syndrome. The risk is influenced by maternal age, not family history. If both parents are carriers of the genetic translocation for Down syndrome, the risk may be higher.

What is a congenital disorder caused by having an extra 21st chromosome which results in a flat face short stature and mental retardation?

The congenital disorder caused by having an extra 21st chromosome is called Down syndrome. It is characterized by physical features such as a flat face, short stature, and intellectual disabilities.

Is 1 in 760 high risk for Down syndrome?

A 1 in 760 chance of having a baby with Down syndrome is considered low risk. Typically, a risk of 1 in 150 or higher is considered low risk for Down syndrome. It's always best to discuss any concerns with a healthcare provider for personalized advice.

How likely is it to have a down syndrom baby?

The likelihood of having a baby with Down syndrome increases with the mother's age, with the risk highest for women over 35. On average, the likelihood is around 1 in 700 births. However, it's important to remember that every pregnancy is unique, and individual risk factors can vary. Testing during pregnancy can provide more specific information about the likelihood of having a baby with Down syndrome.

Is there a connection between a Down syndrome child and narcissistic parents or siblings?

Strictly speaking, no. Down's syndrome is a genetic abnormality, which has, as far as is currently known, no hereditary features. Down's Syndrome most often occurs in the babies of women giving birth over the age of 35, and it is thought that the genetic syndrome is due to the breakdown of the genetic material in the ova of women as they age.

Pathological narcissism (as distinguished from ordinary, or healthy narcissism) or Narcissistic Personality Disorder is not currently seen or proven to have any genetic component whatever. The current thinking is that pathological narcissism is a developmental disorder contributed to by neglectful or conversely, over-attentive parenting which lacks both genuine intimacy and realistic or accurate feedback for the child.

The only 'connection' that might be seen (and it's a stretch) --- is that if a pair of parents who both met sufficient criteria to be officially diagnosed with Narcissistic Personality Disorder were to bring up a Down's Syndrome child, they might perceive having such a child as extremely shameful, ignoring or neglecting, or even belittling to abusing the child. Conversely, depending on the peer group of the parents, they might perceive that having such a child could be a source of admiration from others -- they could see and present the child as being "Extra Special" and themselves as grandiosely noble for dedicating themselves to the upbringing of a Down's Syndrome Child. In either case, the child would likely suffer from such parenting in some way.

In this hypothetical situation, siblings would conceivably suffer as well: either from being 'tarred with the same brush" and ignored or belittled in the same way as the Downs Syndrome Child in the first instance; or being utterly ignored for being 'not special enough' in the second.

What is the mode of inheritance of down syndrome?

If a person has a gene for lets say diabetes then it will be passed on to the next generation through reproduction. even if a person does not have diabetes but carries the gene for it the next generation might carry on too.

What is a common autosomal trisomy?

Something tells me that trisomy 21 is not really the most common, but it is the common among babies that actually live. Other trisomies common among live births are those of the 13th and 18th chromosome. Trisomy 16 is the most common known disorder of miscarried fetuses. Trisomy is caused by nondisjunction of a pair of chromosomes during meiosis or mitosis. What causes nondisjunction? If we could figure that out, we might be able put trisomies in the past.
