Position Paper

For my biomedical ethics class I need to write a position paper or case analysis, and I would prefer to do the position paper because I feel it gives me more leeway and availability to express my opinion. However, I am having a very difficult time finding a topic that either interests me or has enough information or is important enough to write about. I would like to write about something in the genetics realm, anything related to it, such as gene therapy, required prenatal screening, selective abortion, whatever. I need to choose a topic but I can't really think of anything, and the ones I listed are either too broad, too narrow, or I just don't want to do it. Any suggestions for a topic?
