Bertucci et al. identified a 36-gene expression profile of HER2+ breast tumors which included altered expression of genes chromosomes 11q and 16q, including the fatty acid desaturase 2 (FADS2) gene [GenBank: AF084559] on chromosome 11q12.2 and the M-cadherin (CDH15) gene [GenBank: D83542] on chromosome 16q24 [28]. This evidence concerns the gene FADS2 and breast neoplasm.
