Abstract

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age. There is evidence for a genetic component in PCOS based on familial clustering of cases. OBJECTIVE: In the present study, the heritability of PCOS was estimated. DESIGN/PARTICIPANTS: Data from 1332 monozygotic twins (genetically identical) and 1873 dizygotic twins/singleton sisters of twins (who share on average 50% of their segregating genes) registered with The Netherlands Twin Register were used. PCOS was defined as less than nine menstrual cycles and acne or hirsutism in agreement with the 2003 Rotterdam consensus. RESULTS: Results point to a strong contribution of familial factors to PCOS. The resemblance in monozygotic twin sisters (tetrachoric correlation 0.71) for PCOS was about twice as large as in dizygotic twin and other sisters (tetrachoric correlation 0.38). Univariate analyses point to strong contributions of genetic factors to the variance in PCOS. Next, a trivariate genetic analysis of oligomenorrhea, acne, and hirsutism was carried out. This analysis confirmed that the familial component in PCOS is due to genetic factors. CONCLUSIONS: This study demonstrated a large influence of genetic factors to the pathogenesis of PCOS, justifying the search for susceptibility genes.

  • Decades of genetic research has characterized PCOS as a polygenic trait that results from interactions between the environment and susceptible genomic traits.

    “Decades of genetic research has therefore characterized PCOS as a polygenic trait that results from interactions between the environment and susceptible genomic traits [27,29,79,88].”

    From Polycystic Ovary Syndrome: An Evolutionary Adaptation to Lifestyle and the Environment (2022) · cites this paper as [79]

    The paper's introductory discussion says a polygenic, multifactorial model is “most likely,” rather than established. The Discussion reports both genetic and unique environmental influences and says weight gain may trigger PCOS in predisposed women. Thus it supports the general account, but the claim states the proposed model and environmental interaction more definitively than the source does. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • The failure to identify a qualitative or monogenic inheritance pattern and the findings from GWAS, Mendelian randomization, familial and twin studies suggest that the heritability of PCOS is likely due to the combination of multiple genes with small effect size.

    “The failure to identify a qualitative or monogenic inheritance pattern and the findings from GWAS, MR, familial and twin studies, suggests that the heritability of PCOS is likely to be due to the combination of multiple genes with small effect size, as has been found with obesity and type 2 diabetes [79,80,94,95,96].”

    Experimental — accuracy not yet measured
  • PCOS is a polygenic trait that results from an interaction between susceptible genomic variants and the environment.

    “PCOS is therefore viewed as a polygenic trait that results from an interaction between susceptible genomic variants and the environment.”
  • Twin studies suggest that the hereditability of PCOS is approximately 70%.

    “Twin studies suggest that the hereditability is ∼70% [112].”

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.
