Genetic Disorder problem. My query.

Dear sir, There is a genetic Disorder in my family where my grandfather has got the first defective gene and is affected with improper legs. With two fingers in each leg. My grandfather has four children out of which my father and my aunt are perfectly alright and me and my aunt's daughter is also perfect . But both my uncles got the defective genes and it has been passed to their children too. One of my uncles child is perfectly alright. And one child alone has been affected with one uncle. In case of my other uncle both the children have been affected by the defective genes.Now i have been recently married I am worried that My children may be affected or not. Please clarify my query. Thanks and Regards N.HEMANTH KUMAR
