Although the links between olfactory transduction and pancreatic cancer remain to be elucidated, a previous sequencing analysis of human pancreatic tumors did find many somatic mutations of the OR genes, including seven genes identified in the current analysis: OR13C3, OR13C5, OR10P1, OR1J2, OR4A16, OR51F2, and OR5D13[40]. This evidence concerns the gene OR5D13 and familial pancreatic carcinoma.
