They used to have it visible, but it's been moved to an archived report. You can still find out from the raw data report here though: https://www.23andme.com/you/explorer/gene/?gene_name=APOE

If you are CC genotype for marker rs7412 AND marker rs429358 your status is APOE4.

Note that there are several other markers/genotypes that can reduce risk, but research appears to point to APOE4 status having the most impact. Also be aware that genetic reports could always have errors due to chance, operational errors, or problems with original research.
