Abstract

Objective Recombinant human growth hormone (GH) can achieve final adult height gain in girls with Turner syndrome (TS), but its efficacy varies widely across individuals. The exon 3-deleted polymorphism of growth hormone receptor (d3-GHR) has been reported to be associated with responsiveness to GH therapy. The short-term growth response of Turner patients to GH therapy was analysed according to their GHR-exon 3 polymorphism genotype. Design and patients This was a retrospective study of 175 TS patients. Auxological and endocrine parameters were measured, and the GHR-exon 3 genotype was analysed. Allelic frequencies of GHR-exon 3 genotype were compared between patients with TS and control individuals. GH had been administered to 147 patients, 115 of which remained pre-pubertal after the first follow-up year. Changes in height standard deviation score (SDS), height velocity (HV), body mass index (BMI), IGF-1 and IGF binding protein-3 (IGFBP-3) concentrations were compared between these patients, grouped according to genotype, after the first follow-up year. Results There was no difference in GHR-exon 3 genotype frequency between the TS and control groups of Koreans. According to the GHR-exon 3 genotype (fl/fl group vs. d3/fl and d3/d3 group), HV gain and height SDS gain did not differ significantly at the first year of GH therapy. Moreover, changes in IGF-1, IGFBP-3 concentration and BMI showed no significant difference between the groups with and without d3-GHR after 1 year o…

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

  • Results from studies of girls with TS are contradictory regarding the effect of d3 alleles on growth response.

    “However, the results from studies of girls with TS are contradictory with some finding a significant effect on height velocity, total gain in height and adult height in girls with TS carrying one or two d3 alleles.130-132 Other studies did not find an effect.133-135”

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.
