Introduction

Get ready to raise awareness and show your support for those affected by trisomy conditions, as March marks Trisomy Awareness Month! Trisomy is a genetic condition where there is an extra copy of a chromosome in the body, causing developmental and medical challenges. This month-long observance was first established in 2011 by the Trisomy Advocacy Group to educate and promote understanding about these conditions. It's a time to celebrate the strength and resilience of individuals with trisomy, as well as honor those who have lost their lives due to it. Let's come together and spread love, acceptance, and hope during this important month.
