I saw that cerebal palsy was linked to genetic abnormalities. Will that change the way my child is treated?

No. It should not change the way she is treated. If there is a genetic link there may be information that allows anticipation of problems and may help head off problems, but it should not impact her treatment in any negative way.
Misinformation. There are some genetic conditions that can share some similar features to some of the problems of cerebral palsy but CP is not genetic. A CP patient can also have a genetic affliction, but would have had CP with or without that condition.
