Hello, my daughter is 16 and handicapped(low tone/ q43-q44 deletion). she has acid reflux at night but fine all day. what can i give her to help?

Can you tell us the : Chromosome on which your daughter has a mutation of the long arm, please? What has been done medically or surgically to treat the ge reflux? Has she had radiologic studies to rule out aspiration? Has a pediatric gastroenterologist performed an endoscopic procedure to look into her esophagus & stomach? Does she have a g-tube, or does she take food orally ? Can she chew & swallow well? Thank you.
