Why 21 March?

21 March 2021, Sunday - World Down Syndrome Day is marked each year on 21st March, beginning in 2006. March 21st (3/21) was selected to signify the uniqueness of the triplication (trisomy) of the 21st chromosome, which causes Down Syndrome.

Down Syndrome (or Trisomy 21) is a naturally occurring chromosomal arrangement that has always been a part of the human condition, being universally present across racial, gender or socioeconomic lines in approximately 1 in 800 live births, although there is considerable variation worldwide. Down Syndrome usually causes varying degrees of intellectual and physical disability and associated medical issues.

People with Down Syndrome have an inherent right to be accepted and included as valued and equal community members. Just like you!
