Both FADD and CCND1 map to a region of chromosome 11 that is frequently subject to amplifications and copy-number gains in breast cancer (FADD and CCND1 map to regions of copy-number gain in 20–30% of Metabric30 and TCGA samples), raising the concern that this long-range eQTL association might be influenced by these samples. Here, CCND1 is linked to breast cancer.
