In brief: The known stats

From the literature: 35% chance if one parent has it.
75% if both parents have it. These are the probabilities. Decidedly less in your case, since not parent but grandparent. Keep in mind: more stressful environment will play a major role is pushing these probabilities forward / more stable environment is always protective against gene expression of any genetic vulnerability. Take care

In brief: Studies demonstrate

That bipolar disorder does run in families but the risk is minimal.
When 1 parent has this diagnosis, the chances of the child having the illness is between 4 and 15%. When neither of the parents has the illness, the chances are 0 to 2%.
