  • Down syndrome is the most commonly occurring chromosomal condition.
  • There are three types of Down syndrome. 95% of people with Down syndrome have Trisomy 21, a full additional copy of chromosome 21, 5% of people with Down syndrome have translocation or mosaicism, and have partial additional copies in all or some cells.
  • People with Down syndrome visit both typical doctors and specialists.
  • Many children with Down syndrome are included in regular education classrooms alongside their peers. Research has shown that this has positive effects on the academic and social experiences of students with and without disabilities.
  • Over 285,000 people participate in over 250 Buddy Walks® across 50 states each year. That’s a lot of celebrating people with Down syndrome!
