**Schedule Note: When registering, you will notice this Zoom event starts differently than what is on the schedule. This link will be used all day including our connection times for our international families, making it appear as if World Chromosome 18 Day is starting at various times not on the schedule. This is to allow the same link to be used all day for the whole event. The schedule linked above reflects the start and end times of each session and presentation.
