My daughter (13 months old) was diagnosed with 4q 13.1-21.1 deletion last week. Unfortunatelly, nobody even the doctors provided us any source or information about this disorder. I have been searching since then and here I am. I know even with the same deletion it may create different problems. So far my baby has developmental delays, low muscle tone and growth delay. Is there anyone out there that would like to share some information and their stories? I am not an optimistic person but I love my baby so much and I would like to help her as much as I can.
