Abstract

Fragile X syndrome (FXS) is associated with intellectual disability and behavioral dysfunction, including anxiety, ADHD symptoms, and autistic features. Although individuals with FXS are largely considered healthy and lifespan is not thought to be reduced, very little is known about the long‐term medical health of adults with FXS and no systematically collected information is available on standard laboratory measures from metabolic screens. During the course of follow up of a large cohort of patients with FXS we noted that many patients had low cholesterol and high density lipoprotein (HDL) values and thus initiated a systematic chart review of all cholesterol values present in charts from a clinic cohort of over 500 patients with FXS. Total cholesterol (TC), low density lipoprotein (LDL) and HDL were all significantly reduced in males from the FXS cohort relative to age‐adjusted population normative data. This finding has relevance for health monitoring in individuals with FXS, for treatments with cholesterol‐lowering agents that have been proposed to target the underlying CNS disorder in FXS based on work in animal models, and for potential biomarker development in FXS. © 2014 Wiley Periodicals, Inc.

  • Individuals with FXS have reduced peripheral cholesterol and triacylglycerol, and an abnormal profile of fatty acids.

    “Individuals with FXS have reduced peripheral cholesterol and triacylglycerol (TAG), and an abnormal profile of fatty acids (FA)19–21, which questions the appropriateness of the lovastatin treatment.”

    From An iPSC-derived astrocyte model of fragile X syndrome exhibits dysregulated cholesterol homeostasis (2023) · cites this paper as [19]

    The Discussion (page not provided) reports lower total, HDL and LDL cholesterol in males with FXS; findings for females were inconclusive. It calls for a future study measuring fasting triglycerides and does not report reduced triacylglycerol or an abnormal fatty-acid profile. (LLM, conf=0.90)

  • Individuals with fragile X syndrome have low cholesterol, HDL, LDL, and ApoA1 levels, and their degree of maladaptive behaviors occurs in inverse relationship to cholesterol levels.

    “Individuals with fragile X syndrome have low cholesterol, HDL, LDL, and ApoA1 levels [39–41], and their degree of maladaptive behaviors occurs in inverse relationship to cholesterol levels [40].”

    From Sterol and lipid analyses identifies hypolipidemia and apolipoprotein disorders in autism associated with adaptive functioning deficits (2021) · cites this paper as [39]

    The Results and Discussion report lower total cholesterol, HDL, and LDL in males with fragile X syndrome; findings in females were less definitive. Our copy does not report low ApoA1 or an inverse relationship between maladaptive-behavior severity and cholesterol levels. The latter claim is specifically attached to citation [40], but the paper's mention of behavioral symptoms does not establish that relationship. (LLM, conf=0.86)

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.
