Fragile X & Chromosome 15 Testing-ASD

KelliO924 · July 2012

Hi guys. My ds, age 3 was diagnosed PDD-NOS. We recently visited the developmental pediatrician and she ordered tests for Fragile X and chromosome 15 (I think deletion?). I know quite a bit about Fragile X and how is passed down, expressed, etc., but I'm having trouble finding any information about chromosome 15 that isn't about Prader-Willi or Angelman's syndrome. Any information (especially chromosome 15's relation to ASD) is much appreciated, I always feels better going into something knowing more about it rather than less. Thank you so much!

Some kids with ASDs have deletions/duplications on Chromosome 15.

There are a whole host of issues associated with #16.

Chromosome 15 and 16 are closely related. My youngest son has a 16p11.2 duplication.
