19q13.2 |
| Allelic Variant 1 |
107741.0015; APOE3 ISOFORM |
| Identified Mutation |
CYS112 AND ARG158; Weisgraber et al. [J. Biol. Chem. 256: 9077-9083 (1981)] and Rall et al. [Proc. Nat. Acad. Sci. 79: 4696-4700 (1982)] identified one of the 3 major apolipoprotein E isoforms, apolipoprotein E3. The variant has Cys112 and Arg158. This is the most common variant, with frequencies of 40% to 90% in various populations. |
