Is down syndrome autosomal or sex linked?

Is down syndrome autosomal or sex linked?

None of the above: Down syndrome happens when an extra 21 chromosome is present in all the cells of the body. It happens before conception when the donor egg fails to shed one of its 21 chromosomes in the formation of the egg; the male 21 joins the female pair & creates an embryo with 3 number 21's. It has nothing to do with traits or mutations in the gene code. ...Read more

What is the chance of getting down syndrome?

If Mom is 36 at term: Risk of having a fetus with DS at 16 weeks' gestation is 1:200; risk of having a full-term baby with DS is 1:275. If mom is 37 at term, risk at 16 weeks is 1:150; at term, 1:225, because some pregnancies are lost. Comprehensive 1st trimester screening & integrated 1st & 2nd trimester screening calculate risk by specific hormone & protein levels in mom's blood + fetal ultrasound + maternal age. ...Read more

Variable: A thorough assessment of anyone's risks for pregnancy includes age, pre-pregnancy health ; medications, and an assessment of the genetic input from both parents. A 43 yo has ~1/30 risk of a trisomy 21 Down syndrome birth, added to a general 4% risk with any pregnancy for an unexpected event (cleft, premi, illness). A consultation with a genetic counselor could define your specific risks. ...Read more

In what way can you tell if you have down syndrome?

Chromosome test: Down syndrome is a pattern of malformation ; disordered development related to extra chromosome material carried by the patient. It's most common form involves an extra 21 chromosome, (trisomy 21) in every cell in the body. Less than 10% are mosaics that have a percentage of t21 and some normal. Others have cells with extra 21 material stuck on another chromosome. It is confirmed by a chromosome test. ...Read more

Trisomy 21: Down syndrome is the classic presentation clinically of the congenital malformation syndrome also known as Trisomy 21. Classic features may include simian creases, epicanthal folds, upslanting palpebral fissures, flat nasal bridge, hypertelorism, low set ears, endocardial cushion defects of the heart, atlanto-axial joint instability, blood dyscrasia, mental retardation, etc... ...Read more

How were people with Down syndrome treated in the 1940s?

Institutionalized: A common approach to ds patients in the 40's was to reccomend institutionalization. Up to 1/3 had a potentially lethal heart defects that could not be fully assessed or fixed at the time & many other issues that seemed futile. Families were encourages to house them in specialized centers where they would be given basic care for what was expected to be a short life of 2-30 yrs. ...Read more

What are the mental limitations of someone with Down syndrome?

About 70% of people: With DS have mild -moderate Intellectual Disability (ID) by standardized tests of abstract thinking, problem-solving, planning, academic learning, etc. & of adaptive ability in cognitive, social & practical areas. Mild ID = IQ 50-70; moderate ID = IQ 35-49. Some have IQ's in the Borderline Range of normal, 70-79; others, severe ID = IQ 20-34 or profound ID = IQ l<20. See www. Ndss. Org for more. ...Read more

What are common conditions resulting from nondisjunction (ex. Down syndrome)?

See below: There are multiple more common nondisjunction syndromes like down's syndrome (trisomy 21) including: trisomies 18, 13, 8, 9, 16 and monosomies like: chromosome 7 or turner's syndrome - monosomy x. But nondisjunction can happen to any of the chromosomes. The most recognized are down's syndrome and turner's syndrome. Most others are not compatible with life. ...Read more

What happens if a person with Down syndrome marries a person without down syndrome?

Interesting couple: This is a realistic issue for those working with mentally challenged adults. Some patients function at the upper end of the DS intellect, with capabilities of strong personal relationship. All 21 trisomy males are functionally sterile, but females are capable of reproduction. Such a pair would have many challenges in life, but could do better than many "normal" couples. ...Read more

What are the mechanisms of down syndrome?

What are the mechanisms of down syndrome?

Several possible: The features of Down syndrome seem to be dependent on the addition of one extra segment of a 21 chromosome. You can get there several ways. The traditional ds (~95%) has 3 copies of a 21 chromosome. About 4% have the specific extra 21 piece stuck on a regular chromosome. About 1% have a mosaic of some normal and some 21 trisomy in variable amounts. ...Read more

How can I tell if my baby has down syndrome?

How can I tell if my baby has down syndrome?

Physical and genetic: Down's syndrome is a genetic disorder having one too many of the 21 chromosome. Most are detected on the triple screen, followed by genetic testing on amniocentesis. However, there are physical signs to look for: a single palmar crease, very weak musculature, distinct facial features, and heart defects. There are other smaller signs. There will be developmental delay, and other health issues later. ...Read more
