Abstract

CONTEXT: PAPSS2 (PAPS synthase 2) provides the universal sulfate donor PAPS (3'-phospho-adenosine-5'-phosphosulfate) to all human sulfotransferases, including SULT2A1, responsible for sulfation of the crucial androgen precursor dehydroepiandrosterone (DHEA). Impaired DHEA sulfation is thought to increase the conversion of DHEA toward active androgens, a proposition supported by the previous report of a girl with inactivating PAPSS2 mutations who presented with low serum DHEA sulfate and androgen excess, clinically manifesting with premature pubarche and early-onset polycystic ovary syndrome. PATIENTS AND METHODS: We investigated a family harboring two novel PAPSS2 mutations, including two compound heterozygous brothers presenting with disproportionate short stature, low serum DHEA sulfate, but normal serum androgens. Patients and parents underwent a DHEA challenge test comprising frequent blood sampling and urine collection before and after 100 mg DHEA orally, with subsequent analysis of DHEA sulfation and androgen metabolism by mass spectrometry. The functional impact of the mutations was investigated in silico and in vitro. RESULTS: We identified a novel PAPSS2 frameshift mutation, c.1371del, p.W462Cfs*3, resulting in complete disruption, and a novel missense mutation, c.809G>A, p.G270D, causing partial disruption of DHEA sulfation. Both patients and their mother, who was heterozygous for p.W462Cfs*3, showed increased 5α-reductase activity at baseline and significantly increased production of active androgens after DHEA intake. The mother had a history of oligomenorrhea and chronic anovulation that required clomiphene for ovulation induction. CONCLUSIONS: We provide direct in vivo evidence for the significant functional impact of mutant PAPSS2 on DHEA sulfation and androgen activation. Heterozygosity for PAPSS2 mutations can be associated with a phenotype resembling polycystic ovary syndrome.

  • PAPSS2 mutations clinically result in androgen excess manifesting with premature pubarche and a phenotype in women resembling polycystic ovary syndrome (PCOS), also observed in heterozygous carriers of major loss-of-function mutations.

    “Clinically this results in androgen excess manifesting with premature pubarche and a phenotype in women resembling polycystic ovary syndrome (PCOS), also observed in heterozygous carriers of major loss-of-function mutations (Noordam et al., 2009, Oostdijk et al., 2015).”

  • Mutations of PAPSS2 lead to impaired PAPS synthesis and thus impaired sulfation, which results in enhanced conversion of DHEA to active androgens.

    “Mutations of PAPS synthase type 2 (PAPSS2) lead to impaired PAPS synthesis and thus impaired sulfation, which results in enhanced conversion of DHEA to active androgens.”

    From Intracrine androgen biosynthesis, metabolism and action revisited (2018) · cites this paper as Oostdijk et al., 2015

  • Inactivating mutations in the PAPSS2 gene are associated with premature puberty, hyperandrogenism, and anovulation, with reduced DHEAS and elevated androgen levels.

    “Inactivating mutations in PAPSS2 gene are associated with premature puberty, hyperandrogenism, and anovulation, with reduced DHEAS and elevated androgens levels.”
  • PAPSS2 deficiency is characterized as a monogenic cause of excess adrenal androgens.

    “Thus, PAPSS2 deficiency is characterized as a monogenic cause of excess adrenal androgens ( 29 , 30 ).”
  • SULT2A1 converts the androgen precursor DHEA into its sulfate ester DHEAS, which is inactive, preventing conversion of DHEA into active androgens and possible hyperandrogenism.

    “The SULT2A1 enzyme (DHEA sulfotransferase) converts the androgen precursor DHEA into its sulfate ester DHEAS, which is inactive ( Figure 1 ). This reaction prevents conversion of DHEA into active androgens escaping possible hyperandrogenism.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
