Deleterious Missense Mutations and Silent Polymorphism in the Human 17β-Hydroxysteroid Dehydrogenase 3 Gene (HSD17B3)1

Abstract

Isozymes of 17β-hydroxysteroid dehydrogenase (17βHSD) regulate levels of bioactive androgens and estrogens in a variety of tissues. For example, the 17βHSD type 3 isozyme catalyzes the conversion of the inactive C19-steroid androstenedione to the biologically active androgen, testosterone, in the testis. Testosterone is essential for the correct development of male internal and external genitalia; hence, deleterious mutations in the HSD17B3 gene give rise to a rare form of male pseudohermaphroditism termed 17βHSD deficiency. Here, 2 additional missense mutations in the HSD17B3 gene in subjects with 17βHSD deficiency are described. One mutation (A56T) impairs enzyme function by affecting NADPH cofactor binding. A second mutation (N130S) led to complete loss of enzyme activity. Also, a single base pair polymorphism in exon 11 of the HSD17B3 gene is described. The polymorphic A allele encodes a protein with a serine rather than a glycine at position 289 (GGT → AGT). The frequency of the G allele (Gly) was 0.94, and that of the A allele (Ser) was 0.06. No difference in the frequencies of the G and A alleles was detected in 32 apparently normal women and 46 women with polycystic ovary syndrome. Enzymes bearing either glycine or serine at this position have similar substrate specificities and kinetic constants. The current findings boost to 16 the number of mutations in the HSD17B3 gene that impair testosterone synthesis and cause male pseudohermaphroditism, and add 1 apparently silent polymorphism to this tally.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Molecular genetic testing helps to establish the diagnosis of 17βHSD3 deficiency, which has implications for management of the adolescent.

    “Molecular genetic testing helps to establish the diagnosis, which has implications for management of the adolescent (518).”
  • Children with 17βHSD3 deficiency and functional testes begin to virilize at puberty.

    “As in 5␣-reductase type 2 deficiency, children with 17␤HSD3 deficiency and functional testes begin to virilize at puberty, and these patients sometimes adopt the male gender as adults.”
  • Patients with 17-ketosteroid reductase deficiency harbor mutations in the HSD17B3 gene, proving the central role of this enzyme in male sexual differentiation.

    “When the cDNA derived from the 67-kb gene for 17␤HSD3 was cloned, patients with 17-ketosteroid reductase deficiency were found to harbor mutations in this HSD17B3 gene (516 -518), proving the central role of this enzyme in male sexual differentiation.”
  • The presentation of 17βHSD3 deficiency is indistinguishable from that of partial androgen insensitivity syndrome or 5α-reductase type 2 deficiency, with most newborns assigned a female sex of rearing.

    “The presentation is thus indistinguishable from that of partial androgen insensitivity syndrome or 5␣-reductase type 2 deficiency, with most newborns assigned a female sex of rearing (518).”

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.
