What is Down Syndrome?

Down syndrome is a chromosomal disorder that is caused by an error in cell division that results in an extra 21st chromosome. Down syndrome is sometimes called Down's Syndrome or Trisomy 21.

When was Down Syndrome discovered?

In 1866, Doctor John Langdon Down first described Down syndrome as a disorder, but he misunderstood how Down syndrome arises. The cause of Down syndrome was discovered rather recently in 1959. Down syndrome is a genetic disorder and the most common cause of cognitive impairment.

Different Types Of Down Syndrome

It is three types of different Down Syndrome: Trisomy 21, translocation, and mosaicism. Trisomy results in an embryo with three copies of chromosome 21 instead of the usual two. Translocation accounts for about 4% of cases of Down Syndrome the total number of chromosomes in cells remains 46. Mosaicism is diagnosed when its a mixture of two type of cells some containing the usual 46 chromosomes and some containing 47.

What Causes Down Syndrome ?

The cause of this specific syndrome is still unknown today. Maternal age is the only factor that has been linked to increase the chance of a child being born with it. There is no scientific research that tells us down syndrome is caused by environmental factors.
