Expression of CYP7A1 in cultured HEK 293 cells showing absence of cholesterol 7-α hydroxylase activity in the L413fsX414 mutant. Cells were transfected with normal or mutant CYP7A1 plasmids (in pCDNA3.1) and incubated with [4-14C]-cholesterol. Sterols extracted from the cell media were analyzed by TLC.
