Abstract

21-Hydroxylase deficiency which causes congenital adrenal hyperplasia is one of the most common defects of adrenal steroidogenesis. There are two 21-hydroxylase genes in man, A and B, and these have been mapped to the HLA class III region. Only the 21-hydroxylase B gene is thought to be active. To understand the molecular basis of congenital adrenal hyperplasia in a patient with the salt-wasting form of the disease, we cloned and characterized his single 21-hydroxylase B gene. The nucleotide sequence of this gene and a 21-hydroxylase B gene from a normal individual have been determined. Comparison of the two sequences has revealed 11 nucleotide alterations, of which two are in the 5' flanking region, four are in introns, one is in the 3' untranslated region and four are in exons. Two of the differences in exons cause codon changes, with Ser-269 and Asn-494 in the normal 21-hydroxylase B gene being converted to Thr and Ser, respectively. These amino acid substitutions may give an insight into those residues necessary for 21-hydroxylase enzymatic activity. We have also confirmed that the 21-hydroxylase A gene is a pseudogene due to three deleterious mutations in the exons. In addition, comparison of the 21-hydroxylase B gene sequence with other published sequences indicates that this microsomal cytochrome P-450 may be polymorphic.

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

  • The CYP21 genes consist of 10 exons, are about 3.4 kb long, and differ in only 87 or 88 of these bases.

    “The CYP21 genes consist of 10 exons (373), are about 3.4 kb long, and differ in only 87 or 88 of these bases (357-359).”

    From The Molecular Biology, Biochemistry, and Physiology of Human Steroidogenesis and Its Disorders (2011) · cites this paper as [359]

    The Results (page unavailable) say the two 21-hydroxylase genes have 10 exons and are 3.3 kb long, close to the claimed approximate length. But the paper reports 90 nucleotide differences between them, not 87 or 88. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Characterization of the P450c21 protein and gene cloning show there is only one 21-hydroxylase encoded by a single functional gene on chromosome 6p21.

    “However, characterization of the P450c21 protein (355) and gene cloning show there is only one 21-hydroxylase encoded by a single functional gene on chromosome 6p21 (356 -359).”

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.
