Down syndrome is AKA Trisomy 21.
there are 3 autosomes on the 23 chromosome. it isn't x linked, but is randomly mutated and in some cases autosomal.
It doesn't affect chromosomes but it adds an extra 21st chromosome
Klinefelter = XXY Turner's = X Klinefelter syndrome is the extra X and can lead to somewhat of a female secondary sexual characteristic in men. Turner's is the single X some women receive and can cause short stature and lack of secondary sexual characteristics.
The term is monosomy, in which one chromosome of a pair is missing. Turner's Syndrome is an example of monosomy, in which there is only one sex chromosome, which is the X chromosome. Humans with Turner's Syndrome are female, but sterile. The genotype of the sex chromosomes in Turner's Syndrome is XO, in which O represents a missing chromosome.
Down syndrome is not caused by premature birth. Down syndrome is present in the embryo from the time of conception. Down syndrome, in contrast, may lead to premature birth.
Jacobs Syndrome, also known as XYY syndrome, is a genetic condition in males where they have an extra Y chromosome. This can lead to taller height and potential developmental delays or learning disabilities, although symptoms can vary widely. It is important for individuals with Jacobs Syndrome to receive appropriate support and medical care based on their individual needs.
NO!!
No, but consuming alcohol during pregnancy can lead to impaired mental development in a condition called Fetal Alcohol Syndrome.
People with high functioning down syndrome can in some cases lead completely independent lives.
No
No, Down Syndrome is strictly a genetically inherited condition; though taking drugs during pregnancy can lead to other health problems for the baby.
Most can lead good lives but will have medical problems.
does fanconi syndrome lead to cancer
phsychiatrist A Downs Syndrome diagnosis is confirmed with a genetic test, which looks for the extra chromosome (Downs chromosome) that is present. Autistic diagnostic tests such as the CARS, CHAT, ADOS, as well as the Bayleys Scale and Monte Griffiths assesment can be carried out by a psychiatrist (because they rely on observation and parental imput in some parts) but I would recommend seeing a developmental paediatrician because they primarily deal with childrens developmental issues, plus they can along with occupational therapists look for other indicators of autism plus look at whether your child has another developmental problem other than Downs syndrome or autism. They may also test your child's blood for things like lead levels (to rule out lead poisoning) haemogobin levels, and look at if your child may have Fragile X syndrome, or urine testing for metabolic problems or do an EEG to look for indications your child may have had seizures or something else that may have led to regression in your child's development, plus they may get several different tests like hearing tests to rule out deafness or something else that it could be so I would personally recommend a developmental paediatrician because they may take a more wholistic approach and are experts in the field. I hope this has helped you know what to look for. Good luck.
