Hi everyone! Its been awhile since I've been on here. I from the United States in California, my 2 1/2 yr old Jason has Chromosome 12q deletion (12q21.2q21.31) .For those of you that don't know, I have a Facebook group called Chromosome 12q Deletion , if you would like to join and meet the families there from all over the world. We have over 30children with this disorder and we have been learning more about chromosome 12q disorders than we have from our doctors. Please feel free to contact me on Facebook so you can be added to the group. My name is Elizabeth Anderson, Facebook group - Chromosome 12q Deletion, or email me at wazzuplizard@yahoo.com
