Probability of inheriting parkinson’s disease

Patient: We have a family history of parkinson disease. My grand dad and two of his brothers died of this disease. However it has only affected males. How many chances are there of my dad having this disease (he is 45 and fit right now but his cousin (38) has already developed symptoms. and since females of our family never got affected by this disease is it possible that my (i’m female) child can have this disease?
