is a gene on chromosome # 19 which encodes a glycoprotein (a combo protein and sugar chain) called E epsilon Apolipoprotein. The molecule seems to be active in the mechanism that gets cholesterol and lipoproteins to the needed
places in neurons (and some other cells). There are known variations in the product of this gene. The type 4 variant of the E-Apolipoprotein gene seems to result in a diminished ability to repair neurologic damage. Thus it is
found in higher percentages in cases of neurologic trauma which do badly. The implication is that the damage might have otherwise repaired.
