WebFemales with a mutation in this gene have an 80% lifetime risk of developing breast cancer. The penetrance of the condition is therefore 80%. [2] High and low penetrance: If an allele is highly penetrant, then the trait it produces will almost always be apparent in an individual carrying the allele.

WebIn this paper, we propose a novel gene- and a pathway-level approach in the case where several independent GWAS on independent traits are available. The method is based on a generalization of the sparse group Partial Least Squares (sgPLS) to take into account groups of variables, and a Lasso penalization that links all independent data sets.
