W228Ter (W210Ter)
(ApoE3 Washington)
Blood Lipids/Lipoproteins, Hyperlipoproteinemia Type III Substitution

Generated a truncated protein and, in homozygous form, nearly eliminated ApoE from plasma. Lipoprotein and lipid profiles in blood indicated a reduction in hepatic removal of remnant lipoprotein particles.

Coding Exon 4 Lohse et al., 1992
A227_E230del (A209_E212del)
Blood Lipids/Lipoproteins, Cardiovascular Disease, Hyperlipoproteinemia Type III Deletion

Predicted to cause a frameshift introducing a stop codon at amino acid 247. In homozygous form, resulted in near elimination of ApoE protein.

Coding Exon 4 Feussner et al., 1996
