Diana Parksion from the Silicon Valley Down Syndrome Network submitted this World Down Syndrome Day button to help to start conversations about the condition and to create awareness. "People who wore the buttons told me they had people come up to them as ask 'what does 3-21 mean?'" said Diana. "They were then able to tell the person about Down Syndrome, which is a genetic condition where a person is born with three sets of the 21st chromosome - thus 3-21."
