My son is 2 & just had chromosome test b/c facial features such as small jaw & high palate &he's not speaking well .he smart understands me well. dr says just precaution. are these serious disorders?

Try not to fret.: Some syndromes do not have intellectual disability as part of their neurodevelopmental profile, & some do. The newer genetic microarray tests yield more information than chromosome analysis. Call your state health division's early intervention program for free assessment of all areas of your son's development. He'll benefit from therapy now, even if it's an isolated expressive language delay.

Perhaps: If your child has craniotomy-facial anomalies such as jaw-size discrepancies, please take your child to a pediatric dentist now, and an orthodontist at age 7. It sounds like your child may have malrelationships that will not self-correct and would benefit from interventional guidance.

Maybe: Some can be. The important thing is to find a diagnosis, then you can be counseled on the seriousness and what the future may hold.
