Abstract

1. Autism is a severe neurodevelopmental disorder with potential genetic and environmental etiologies. Recent genetic linkage reports and biochemical analysis of postmortem autistic cerebellum point to Reelin, an important secretory extracellular protein, as being involved in the pathology of autism. 2. We hypothesized that blood levels of Reelin and its isoforms would be altered in autistic twins, and their first degree relatives versus normal controls. 3. We measured blood levels of unprocessed Reelin (410 kDa) and its proteolytic cleavage products (Reelins 330 and 180 kDa) as well as albumin and ceruloplasmin in 28 autistic individuals, their parents (13 fathers, 13 mothers), 6 normal siblings, and 8 normal controls using SDS-PAGE and western blotting. 4. Results indicated significant reductions in 410 kDa Reelin species in autistic twins (-70%, p < 0.01), their fathers (-62%, p < 0.01), their mothers (-72%, p < 0.01), and their phenotypically normal siblings (-70%, p < 0.01) versus controls. Reelin 330 kDa values did not vary significantly from controls. Reelin 180 kDa values for parents (fathers -32% p < 0.05 vs. controls, mothers -34%) declined when compared to controls. In contrast autistic Reelin 180 kDa increased, albeit nonsignificantly versus controls. Albumin and ceruloplasmin values for autistics and their first degree relatives did not vary significantly from controls. There were no significant meaningful correlations between Reelin, albumin and ceruloplasmin levels, age, sex, ADI scores, or age of onset. 5. These results suggest that Reelin 410 deficiency may be a vulnerability factor in the pathology of autism.

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.
