Topic: large-scale sequencing

Studies of families with inherited breast-cancer risk led to BRCA1 and subsequently many other susceptibility genes. This seminar examines how large-scale sequencing and population studies have refined tumour associations and penetrance estimates. It moves from a simple dominant-inheritance model toward multifactorial risk, considering genetic and environmental modifiers that could support individualized surveillance and management.

Microbes make up the vast majority of the tree of life. While we know very little about most microbial species, large-scale sequencing is giving us glimpses of the diversity that exists both within species and in ecosystems. The challenge now is to find the patterns in this diversity and understand them. This session features provocative talks on attempts to meet that challenge.
