We discuss (a) the role of the nuclear receptors DAX‐1 (NR0B1) and steroidogenic factor‐1 (SF‐1, NR5A1) in human adrenal and reproductive dysfunction; (b) multisystem growth restriction syndromes due to gain‐of‐function in the growth repressors CDKN1C (IMAGE syndrome) and SAMD9 (MIRAGE syndrome), or loss of POLE1; (c) nonclassic forms of STAR and P450scc/CYP11A1 insufficiency that present with a delayed‐onset adrenal phenotype and represent a surprisingly prevalent cause of undiagnosed PAI; and (d) a new sphingolipidosis causing PAI due to defects in sphingosine‐1‐phosphate lyase‐1 (SGPL1). Here, CYP11A1 is linked to sphingolipidosis.
