Trisomy Awareness Month is observed every March to increase understanding of trisomy conditions. Trisomy occurs when a person has three copies of a chromosome, which can affect individuals in many ways. While Down syndrome is one type of trisomy, this month reminds us that trisomy is about more than just Down syndrome.
It’s a time to raise awareness, support individuals and families affected by trisomy, and celebrate the unique strengths and contributions of everyone living with these conditions.
