Abstract

BACKGROUND: A substantial group of patients with cholestatic liver disease in infancy excrete, as the major urinary bile acids, the glycine and taurine conjugates of 7alpha-hydroxy-3-oxo-4-cholenoic acid and 7alpha,12alpha-dihydroxy-3-oxo-4-cholenoic acid. It has been proposed that some (but not all) of these have mutations in the gene encoding delta(4)-3-oxosteroid 5beta-reductase (SRD5B1; AKR1D1, OMIM 604741). AIMS: Our aim was to identify mutations in the SRD5B1 gene in patients in whom chenodeoxycholic acid and cholic acid were absent or present at low concentrations in plasma and urine, as these seemed strong candidates for genetic 5beta-reductase deficiency. PATIENTS AND SUBJECTS: We studied three patients with neonatal onset cholestatic liver disease and normal gamma-glutamyl transpeptidase in whom 3-oxo-delta(4) bile acids were the major bile acids in urine and plasma and saturated bile acids were at low concentration or undetectable. Any base changes detected in SRD5B1 were sought in the parents and siblings and in 50 ethnically matched control subjects. METHODS: DNA was extracted from blood and the nine exons of SRD5B1 were amplified and sequenced. Restriction enzymes were used to screen the DNA of parents, siblings, and controls. RESULTS: Mutations in the SRD5B1 gene were identified in all three children. Patient MS was homozygous for a missense mutation (662 C>T) causing a Pro198Leu amino acid substitution; patient BH was homozygous for a single base deletion (511 delT) causing a frame shift and a premature stop codon in exon 5; and patient RM was homozygous for a missense mutation (385 C>T) causing a Leu106Phe amino acid substitution. All had liver biopsies showing a giant cell hepatitis; in two, prominent extramedullary haemopoiesis was noted. MS was cured by treatment with chenodeoxycholic acid and cholic acid; BH showed initial improvement but then deteriorated and required liver transplantation; RM had advanced liver disease when treatment was started and also progressed to liver failure. CONCLUSIONS: Analysis of blood samples for SRD5B1 mutations can be used to diagnose genetic 5beta-reductase deficiency and distinguish these patients from those who have another cause of 3-oxo-delta(4) bile aciduria, for example, severe liver damage. Patients with genetic 5beta-reductase deficiency may respond well to treatment with chenodeoxycholic acid and cholic acid if liver disease is not too advanced.

  • Inherited AKR1D1 mutations cause bile-acid deficiency in infants characterized by reduced bile acid formation and accumulation of hepatotoxic Δ4-3-keto and 5α-reduced allo-bile acids.

    “Inherited mutations in AKR1D1 have been studied in patients with bile-acid deficiency that develops in infants and is characterized by reduced formation of bile acids and accumulation of Δ4-3-keto and 5α-reduced (allo-bile acids) which are hepatotoxic.”
  • Seven point mutations are known in patients with 5β-reductase deficiency: Leu106Phe, Pro133Arg, Gly223Glu, Pro198Leu, Asp241Val, Arg261Cys, and Arg266Glu.

    “seven point mutations have been identified in patients with 5β-reductase deficiency: Leu106Phe, Pro133Arg, Gly223Glu, Pro198Leu, Asp241Val, Arg261Cys and Arg266Glu [95–97, 99, 100].”
  • The deficiency is exacerbated by inability to form sufficient bile acids to feedback-inhibit CYP7A1, leading to further elevation of allo-bile acids.

    “This deficiency is exacerbated by the inability to from sufficient bile acids to feed-back and inhibit the rate determining step in the pathway, 7α-hydroxylase (CYP7A1), and thus the formation of allo-bile acids will be further elevated [95–99].”
  • SNPs in AKR1C1, AKR1C2, and AKR1C4 have been studied at the protein level, and Phe46Tyr has been associated with disease.

    “So far SNPs in AKR1C1, AKR1C2 and AKR1C4 have been studied at the protein level and Phe46Tyr has been associated with disease [95–97, 99, 103, 104].”
  • Mutations of AKR1D1 lead to severely reduced to completely absent urinary 5β-reduced steroid excretion and hepatic failure, as AKR1D1 is essentially involved in hepatic bile acid synthesis, but no other clinical manifestations.

    “Mutations of AKR1D1 lead to severely reduced to completely absent urinary 5β-reduced steroid excretion and hepatic failure, as AKR1D1 is essentially involved in hepatic bile acid synthesis, but no other clinical manifestations (Gonzales et al., 2004, Lemonde et al., 2003, Palermo et al., 2008).”

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.
