What Is Downs Syndrome
1. Introduction Down syndrome is a genetic condition which causes a certain level of characteristic physical appearance and a disability in learning. The genetic condition is produced by a problem in gene and this takes place before birth. There is a certain grade of intellectual disability this differs between each person. Babies which are born with Down’s syndrome are diagnosed with the disorder after birth they are most likely to have below average weight as well as length at birth, a flat back of the head and eyes which slant outwards and upwards. Children who have the disorder may share the common physical features but are not the same. The child with the condition will look like their mother or father than other …show more content…
Every cell in the body is not exactly the same, 1% of the syndrome cases most cells in the body have an additional chromosome while some don’t this is known as mosaicism. The Mosaic trisomy 21 takes place when the error in the cell division happens early in development though it is after the sperm and the normal egg unite. This can also take place in early development when there are some cells who lose an extra chromosome 21 which was present at conception. Symptoms for this form vary between the Trisomy 21 but this depends on the amount of cells which have an extra chromosome.
Translocation Down’s syndrome
This type of Down’s syndrome is caused when there is a chromosome which breaks off and attaches itself to another chromosome. There are three 21 chromosome but one 21 chromosome attaches to alternative chromosome. Health problems caused by Down Syndrome is caused by the genetic material from the extra 21 chromosome. The extra 21 chromosome can be attached to any other chromosome numbers such as 22 15 in some rare cases the chromosome 21 can attach to each other.
There are some cases where the parent who does not have Down Syndrome may carry a translocation in chromosome 21 and this can be passed on to the siblings and cause the syndrome. When the parent chromosomes are studied it can reveal if this was the cause of the …show more content…
History and Research of Down syndrome
English Physician John Langdon Down was the founder of Down syndrome in 1861. He helped differentiating the condition from mental disability. “Monogoloid” was the name given at the time for people who had Down Syndrome this as due to his opinion that children with child’s syndrome have very similar characteristics to people from a race called Blumenbach’s Mongolian. This name used had become uncommon after the 1970s as it was judgemental and inaccurate
Usually many people with the syndrome were either abandoned or killed from the public. In the 20th century it had become common for such individuals to not receive suitable treatment for the complications like defects in vision, problems in the intestines and heart disorders. As this was the case most children would die during early adulthood or as
