My name is Erica and my youngest son, Alex, is three and a half. He has a very rare genetic condition; he has a duplication on his 4th chromosome. There is no syndrome or name for his genetic condition. In fact, many doctors have tried to find a similar case and Alex is the only one with this specific condition. This is wonderful in many ways because it means there's no limit to Alex's potential and he gets to show us what he can do without any specific labels. On the other hand, it's tough because we don't know what issues we're dealing with or looking for until we run into trouble. There are no support groups for this specific condition and we don't have anyone to watch to have an idea of what the future holds. But all of this has freed Alex and our family to simply enjoy each day knowing Alex will show us what he's ready for. We are so blessed to have a big and very loving family who surround us on this journey.
