Analysis of expression array data available in Oncomine revealed that LRP1b is expressed in human breast cancer cells, although we were unable to detect recurrent deletions of LRP1b in a collection of sporadic primary human breast cancers, suggesting that deletion of this gene may be a relatively rare event (Additional file 4), or that it may be associated with a specific subtype of disease not represented by the collection we analyzed [31]. This evidence concerns the gene LRP1B and breast cancer.
