World Down Syndrome Day

Every year, on March 21st, our family, and people all over the world, celebrate World Down Syndrome Day. What do I mean by "celebrate". I mean, we wear mis-matched (or crazy) socks and post the pictures all over social media. You should try it! The thought behind the mismatched socks is due to the change in the 21st chromosome that was thought to look like a pair of mismatch socks.

If you hear us refer to Lilly as a "little extra" its because, scientifically, she is. Everyone with Down Syndrome has extra of the 21st chromosome. Something most people aren't aware of is that there are three types of Down Syndrome:

1. Trisomy 21

About 95% of people with Down syndrome have Trisomy 21. This means every cell in the body has three copies of chromosome 21 instead of the usual two. This typically happens by chance during cell division and isn’t inherited.

--This is the kid Lilly was diagnosed with--

2. Translocation

This type accounts for about 3–4% of cases. Instead of having a full extra chromosome, part of chromosome 21 attaches (or “translocates”) to another chromosome. In some cases, this type can be inherited from a parent who carries a rearranged chromosome.

3. Mosaic

This is the rarest form, affecting about 1–2% of people with Down syndrome. Some cells have the typical two copies of chromosome 21, while others have three. Due to this “mix” of cells, individuals with mosaic Down syndrome may have fewer or less pronounced characteristics.

So, when you see someone posting pictures of their socks on March 21st, join in.
