Abstract

To the Editor: We report on a family with recessive resistance to the action of thyrotropin-releasing hormone (TRH) due to a nonsense homozygous mutation in the TRH receptor (TRHR) gene (p.R17X). W...

  • In children, L-T4 treatment promotes acceleration of growth velocity allowing attainment of target height.

    “In children, L-T4 treatment was reported to promote an acceleration of growth velocity allowing attainment of target height [11, 28, 43].”

    From 2018 European Thyroid Association (ETA) Guidelines on the Diagnosis and Management of Central Hypothyroidism (2018) · cites this paper as [11]

    Table 1 (page not provided) reports that the proband received levothyroxine and reached 178 cm as an adult, within his parental target-height range of 172 ± 10 cm. The paper does not report an acceleration in growth velocity or establish this treatment effect in children generally. (LLM, conf=0.84)

  • The diagnosis in 3 of 4 probands with biallelic TRHR mutations was made during childhood because of delayed growth accompanied by lethargy and fatigue or by overweight.

    “The diagnosis in 3 of 4 probands with biallelic TRHR mutations was made during childhood because of delayed growth accompanied by lethargy and fatigue or by overweight.”

    From 2018 European Thyroid Association (ETA) Guidelines on the Diagnosis and Management of Central Hypothyroidism (2018) · cites this paper as [11]

    In the section “A Family with Complete Resistance to Thyrotropin-Releasing Hormone” (page unavailable), Table 1 places this paper’s proband at age 11 with height in the 3rd–10th percentile, and the text mentions a previously reported 9-year-old with a similar presentation. Our copy does not report a group of four probands or establish that three were diagnosed because of delayed growth accompanied by lethargy, fatigue, or overweight. (LLM, conf=0.80)

    Experimental — accuracy not yet measured
  • Complete TRH resistance was uncovered by genetic testing in 1 pregnant woman.

    “However, complete TRH resistance was uncovered by genetic testing in 1 pregnant woman [11].”
  • Even complete TRH resistance does not cause severe neonatal hypothyroidism.

    “Though prolonged neonatal jaundice was reported in 1 female, even complete TRH resistance does not cause severe neonatal hypothyroidism.”
  • Impaired thyrotrope stimulation or alterations in the thyroid hormone feedback set point (e.g., TRH resistance or TBL1X mutations) is a pathological mechanism accounting for central hypothyroidism.

    “The pathological mechanisms accounting for CeH are: (a) impaired thyrotrope stimulation or alterations in the thyroid hormone feedback set point (e.g., TRH resistance or TBL1X mutations) [11-13];”

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.
