Seeing who has the marker, Barbara Weber

Interviewee: Barbara Weber. Barbara Weber shows how information from her study on genetic markers associated with inherited breast cancer indicated which family members were at increased risk and which were not. (DNAi Location: Applications > Genes and Medicine > Gene testing > Barbara Weber > Seeing who has the marker)

The numbers underneath them are the genetic markers that we were using and this was actually the pedigree that came into my mind as I was talking to Vicky that day in clinic. This is Vicky here, this is her sister who had died before I met them and this is her sister Denise and what you can see just sort of generally looking is that what we had been doing was circling the markers that went with the disease in this family and they're all the same, you probably can't see them but this, this, this, this, this - all these people who have breast cancer have the same series of markers that are outlined here. And what I could see clearly in my head was that Denise - that's her - didn't have them.
