Fun Little Fact #2

Fun Little Fact #2:
There are 3 different types of Down Syndrome.

There is Trisomy 21 DS (95%), where all cells in the body have that extra 21st chromosome.
There is translocation DS (3-4%) where a piece of the 21st chromosome is attached to the another chromosome, usually chromosome 14.  Translocation DS is the only type of DS that can be inherited and both parents need to have genetic testing to see if it was genetic or by chance.
And finally there is mosaicism DS (1-2%) where only a select few cells have the extra 21st chromosome.

Our sweet Reyna has Trisomy 21.
