POFUT1 and mastitis: The evidence for relationships with milk production traits for these genes was based on the different aspects considered in the Ogorevc et al. [22] database such as gene expression studies related to mammary gland (TFAP2C, FAM110A, CD82, ABCG2) or mastitis (BID, MAFF, AHCY), mouse model studies in which gene knockouts or expression of transgenes resulted in phenotypes associated with the mammary gland (FKBP4, MKL1, POFUT1, CHUK) and association studies of milk production traits (ABCG2, SPP1, SCD).
