My son is 7 years old now, but we were told he was missing a chromosome @ the age of 6 months. He was not doing things that a 6 month baby should be doing.( Mentally & Physically slow.)

I would like to talk to other families like us.

It depends on what chromosome is missing and what the symptoms he shows are.

A missing chromosome is sometimes associated with people on the autism spectrum. Is that what you're talking about? Haven't heard of this one, but Jaime Lee Curtis has an extra chromosome! Try calling the doctor and ask if they know of any local support groups where you could meet with other parents in the same situation. Good Luck! Do you know which chromosome is missing? If so you may be able to google the name of his disorder to find other people in similar situations. It is more common to have an extra chromosome than to be missing one. My prayers are with you.
