Dehydroepiandrosterone (DHEA) sulfotransferase, known as SULT2A1, converts the androgen precursor DHEA to its inactive sulfate ester, DHEAS [corrected], thereby preventing the conversion of DHEA to an active androgen. SULT2A1 requires 3'-phosphoadenosine-5'-phosphosulfate (PAPS) for catalytic activity. We have identified compound heterozygous mutations in the gene encoding human
PAPS synthase 2
(
PAPSS2
) in a girl with premature pubarche, hyperandrogenic
anovulation
, very low DHEAS levels, and increased androgen levels. In vitro coincubation of human SULT2A1 and wild-type or mutant
PAPSS2
proteins confirmed the inactivating nature of the mutations. These observations indicate that
PAPSS2
deficiency is a monogenic adrenocortical cause of androgen excess.
