APOE and familial hyperaldosteronism: There are currently nine genes that underlie FH and FH-like phenotypes; in addition to the before-mentioned well-known causative genes for co-dominant forms of FH and LDLRAP1 or ARH involved in the purely recessive FH, we should also mention the APOE p.LEU167del variant (which causes a dominant form of FH), ABCG5, ABCG8, and LIPA, which ultimately lead to an FH-like phenotype [15].
