Brazil proposed a resolution today to establish an annual World Down Syndrome Day on March 21. Over 60 countries celebrate Down Syndrome Day on that date, chosen because 3/21 represents the three copies of chromosome 21, the unique trait of people with Down syndrome. Oscar-nominated actor Liam Neeson explains the reason for establishing a special day. “Activities and events held on World Down Syndrome Day can have a tremendous impact, showcasing the abilities, talents and accomplishments of people with Down syndrome.”
