Among the genes mapped in BTA16, 11 genes (SLC25A33, PIK3CD, CTNNBIP1, NMNAT1, MTHFR, MIIP, TNFRSF8, TNFRSF1B, DHRS3, TNFSF4, and TNFSF18) were previously found to be related to reproduction traits, such as early pregnancy, stillbirth, oocyte developmental potential, age at first calving, fertility, and embryo survival (details and references listed in Supplementary Table S2). Here, TNFSF18 is linked to Stillbirth.
