How common are chromosome 15 duplications?

[outthere]

Hi all,

DS has been assessed as NOT on the Autism spectrum but he has some very definite traits (flapping, social difficulties/immaturity and fixed interests). He also has low muscle tone, delayed development in most areas (although not global), large head and sensory processing disorder.

All of this has lead to me researching chromosome 15 duplications. From what I understand Isodicentric Chromosome 15 is a very rare condition but I was wondering how common the interstitial duplications are.

I feel that an interstitial duplication could explain a lot of DS's problems, even the fact that he presents as being mildly affected.

How likely is this? Are interstitial duplications as rare as Icodicentric ones?

I would really love to hear from anyone who has any experience...

Thanks

I don't know much about this except have you seen the booklet that unique have produced on Idic 15:

Hi outthere. I would really recommend you email Unique as well - they are a brilliant organisation with loads of information - email is [email protected] - and they may be able to recommend some routes to follow.

There is a support webpage here

Good luck with it all...seems like some progress is being made there for you and DS.

Thanks so much for that everyone, really appreciate the help!

hi
my son has chromosome 15 deletion-Angelman Syndrome. I am friends with lot of idic/int 15 parents on facebook-well worth having look. based up and down the country and they also have a regular meet up. look out for Pamela Taylor or Janie Torrance-there are lots of others who could give you loads of advice. hth x

Thanks Monstermansmum. Are those people to look out for on FB (as opposed to MN)? I've searched for Janie Torrance - is her profile pic of her and two children? If so, do you think she'd mind if I messaged her?

Sorry if I sound pushy, I'm just desperate for someone to talk to!

Thank you so much for your advice, I really appreciate it x

hi outthere, yes janie is herself and 2 boys i think. not sure if there is an idic 15 fb page. i have about 20 ish fb friends that are idic 15, i dont think any of them would mind you messaging them. you can add me if you like and i will introduce you to some if it makes you feel more comfortable. the lady who runs unique also has a son that is either idic or int 15-her name is maz mitchell, also on fb. rachel martin. profile pic is my son. x

Thank you, I really appreciate all that x
