autism, galactosemia and Down syndrome

My son was born with Down syndrome and at 7 months was diagnosed with cataracts in both eyes, the right cataract requiring removal at 11 months.  He has been diagnosed with PDD/NOS by two clinicians and he has also had an obstructive ulcer.  I just recently became aware of the association of galactosemia and cataracts.  Previously I had assumed that the cataracts were due to Down syndrome.  But now I am wondering what the best test would be to determine whether my son might have a form of galactasemia.  My husband also has strong traits of Aspergers and my husband's brother had had a diagnosis of schizophrenia.  (now deceased)

There are blood and urine tests for galactosemia. If you have concerns, definitely bring them up with your pediatrician.
