Abstract

CONTEXT: Exceptional longevity is associated with raised serum TSH. OBJECTIVE: The aim of this study was to examine whether offspring of people with exceptional longevity have elevated serum TSH and whether specific single nucleotide polymorphisms (SNPs) in the TSH-B gene and TSH receptor (TSHR) gene are associated with this phenotype. DESIGN/SETTING/PATIENTS: We measured serum TSH and free T(4) in Ashkenazi Jewish centenarians (n = 232; median age, 97 yr), their offspring (n = 366; median age, 69 yr), and age-matched controls without familial longevity (n = 163; median age, 70 yr). We determined TSH heritability, its distribution, and association with SNPs in the TSH-B and TSHR genes. RESULTS: Offspring had higher median serum TSH [1.68 mIU/liter (97.5% confidence interval, 0.65 to 4.79 mIU/liter)], compared to controls [1.50 mIU/liter (97.5% confidence interval, 0.63 to 3.93 mIU/liter); P = 0.02], with estimated heritability of 0.33 (P = 0.004). Allele frequency of two SNPs in the promoter/enhancer region of TSHR gene, associated with increased serum TSH, was higher in centenarians and their offspring compared to controls (rs10149689 G allele frequency, 0.57 and 0.53 vs. 0.48; P = 0.001 and P = 0.08; odds ratio, 1.56 and 1.22, respectively; and rs12050077 A allele frequency, 0.57 and 0.53 vs. 0.46; P = 0.0001 and P = 0.01; odds ratio, 1.68 and 1.32, respectively). Linkage disequilibrium between the two SNPs was high (r(2) = 0.95), suggesting interaction between them. Furthermore, GA haplotype frequency was significantly higher among centenarians and offspring compared to controls (0.57 and 0.53 vs. 0.46; P = 0.0001 and P = 0.01, respectively). CONCLUSIONS: A heritable phenotype characterized by raised serum TSH is associated with human longevity. Carriers of rs12050077 and rs10149689 SNPs in the TSHR have higher serum TSH, possibly contributing to decreased thyroid function and longevity.

  • The distribution of serum TSH reference interval is right-shifted with age, giving an upper 97.5% confidence interval of around 7.5 mU/L in healthy elderly people.

    “the distribution of serum TSH reference interval is right -shifted with age, 24 -26 giving an upper 97.5% confidence interval of around 7.5 mU/L in healthy elderly people. 2,3”

    From Use of liothyronine (T3) in hypothyroidism: Joint British Thyroid Association/Society for endocrinology consensus statement (2023) · cites this paper as [25]

    The Discussion describes a shift toward higher TSH with age, and Table 1 reports an upper 97.5% CI of 7.15 mIU/L for Ashkenazi Jewish centenarians—reasonably close to 7.5. The paper does not establish that upper limit for healthy elderly people generally; its figure comes from a group selected for exceptional longevity. (LLM, conf=0.86)

  • Serum TSH is higher in some genetic population groups such as Ashkenazy Jews.

    “Serum TSH is, thus, higher in areas of both overt and partial iodine deficiency [8], very high in neonates [9], variable during pregnancy according to gestation [10], increasing at high age [11] and higher in some genetic population groups such as Ashkenazy Jews [12].”

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.
