Hope someone can help. I had my child get developmental bloods due to speech delay. The results came back and showed he had an extra gene in a Chromosome. That's all they said. No explanation as to what this could mean. He is 2.5 years and just has a speech delay. Otherwise seems healthy. They want both parents to get bloods to check for same and then go to genetics centre to discuss results. Anyone shed any light on this as I am a little worried. Thanks.
