Abstract

Although Smith‐Lemli‐Opitz Syndrome (SLOS), a genetic condition of impaired cholesterol biosynthesis, is associated with autism [Tierney et al., 2001 ; Am J Med Genet 98:191‐200.], the incidence of SLOS and other sterol disorders among individuals with autism spectrum disorders (ASD) is unknown. This study investigated (1) the incidence of biochemically diagnosed SLOS in blood samples from a cohort of subjects with ASD from families in which more than one individual had ASD and (2) the type and incidence of other sterol disorders in the same group. Using gas chromatography/mass spectrometry, cholesterol, and its precursor sterols were quantified in 100 samples from subjects with ASD obtained from the Autism Genetic Resource Exchange (AGRE) specimen repository. Although no sample had sterol levels consistent with SLOS, 19 samples had total cholesterol levels lower than 100 mg/dl, which is below the 5th centile for children over age 2 years. These findings suggest that, in addition to SLOS, there may be other disorders of sterol metabolism or homeostasis associated with ASD. © 2006 Wiley‐Liss, Inc.

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

  • Findings of lipid abnormalities have been inconsistent in reported ASD studies.

    “Findings of lipid abnormalities have been inconsistent in reported ASD studies [56–59, 64], although this might be partially due to varying dietary intake in countries where the studies were performed.”

    From Sterol and lipid analyses identifies hypolipidemia and apolipoprotein disorders in autism associated with adaptive functioning deficits (2021) · cites this paper as [56]

    The Results report low cholesterol in 19 of 100 ASD samples, and the Discussion addresses possible explanations within this cohort. Neither passage compares lipid findings across reported ASD studies or says those findings have been inconsistent; searches for conflicting findings in previous studies found no such passage.

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.
