Do you really know what Down syndrome is?
Down syndrome is the most common genetic disorder. While normally, a human cell contains 23 pairs of chromosomes equally inherited from each parent, in Down syndrome some or all of the cells have an extra copy of the chromosome 21.
Most common form of Down syndrome is trisomy 21 and cells of the individuals with Trisomy 21 contain 47 chromosomes instead of the usual number, 46. Trisomy 21 occurs because of an error in cell division called nondisjunction. Error first occurs in the embryo when the 21st pair of chromosomes in either sperm or egg fails to separate and after that as embryo develops; the extra chromosome is replicated in every cell of the body.
Another and least common form of Down syndrome is mosaicism which occurs after fertilication. For mosaicism, the situation is more different compared with trisomy 21 because this time, there are both 46 chromosome and 47 chromosome cells in the body. According to a research conducted to 30 typical Down syndrome children and 30 mosaic Down syndrome, IQ of the mosaic children is 12 points higher than the typical Down syndrome group.
One of the forms of Down syndrome is translocation that occurs during the cell division because of the 21st chromosome’s breaking off and attaching to another chromosome.
The reason of Down syndrome is still unknown, but it is known that the cause of the extra chromosome is neither environmental factor nor anything the mother does before or during her pregnancy.
Some bullet points:
- Today, more than 400,000 people in United States have Down syndrome.
- The chance of having a Down syndrome kid is higher for a younger mom because of higher fertility rates.
- Most of the Down syndrome people have IQs that is enough for public and private educational programs.
- People with Down syndrome have feelings like everyone else.
- People with Down syndrome date, socialize, and marry.
- Down syndrome people are today working at banks, hotels, restaurants, etc.
- Research is showing that, the genes that cause Down syndrome are going to be identified and it will be possible to prevent or improve the problems.
I love a Down Kid..Do you?
It may be difficult to be perfectly optimistic in the beginning. But it is very easy to gain this optimism as you get to know your kid. You’ll realize that you have the most special child; you’ll start not being able to describe your feelings by just the word 'love'. Because it is not just love..It’s attachment, responsibility, self sacrifice, happiness, hope, warmth, patience, a smile, and to feel…It’s the life itself, and it’s yourself..
