In brief: Almost zero
Trisomy 18 (edwards syndrome) is caused by the spontaneous, accidental inclusion of an extra chromosome #18 in the zygote for a total of three.
Your sister's trisomy 18 has no effect on your reproductive risk. Your risk to have a trisomy 18 child is the background incidence of 1/6000 live births.
