Trisomy 21 is the most common type of Down syndrome caused by an extra (third) copy of the 21st chromosome. In essence, a person with Trisomy 21 has three 21st chromosomes (3 – 21).
This spring from March 19th through March 21st, DSC parent, Matt Lyman will ride his bike 321 miles to correspond with World Down Syndrome Day- the 321 miles being just the right number for this ride!
Matt’s goal is to raise awareness about Down syndrome, celebrate his 7-year-old daughter Phoebe, and raise funds to support the DSC programs and services that have meant so much to Phoebe and the Lyman family.
