| 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. |

| Remarks |
This culture was derived from minced fetal skin tissue obtained from a therapeutically aborted fetus of 21 weeks gestational age. This fetus is of mixed race, one parent is black and the other is caucasian. The karyotype is 47,XX,+21 with 2% of the cells examined showing random chromosome loss and established the diagnosis of Down's syndrome. The cell morphology is fibroblast-like. A lung fibroblast culture from this same donor is AG13902. The APOE genotype of the donor subject is E3/E3. The legacy karyotype description shown in this Remark may not be representative of the current available product. |
