Jannine Cody, PhD, and Daniel Hale, MD, with the Chromosome 18 Registry & Research Society have created the above series of podcasts to help you understand what a chromosome abnormality is; how they are diagnosed; how they may lead to health and developmental concerns; and the potential for treatments. They were created for their members but the information applies to those with 1p36 Deletion Syndrome. 1p36 Deletion Support & Awareness would like to thank them for their generosity in allowing us to share these presentations with you.
