This disclosure relates to genetically modified animals. More specifically, this disclosure relates to rodent animals in which an endogenous B4galt1 gene has been modified, e.g., to introduce a mutation that encodes an Asn to Ser substitution in the encoded B4galt1 protein at a position corresponding to position 352 in a human B4GALT1 protein, or to introduce a loss of function mutation (e.g., in a select tissue such as the liver). This disclosure also relates to use of such rodent animals in elucidating the role of B4galt1 in lipid metabolism. |
