Abstract

We describe genetically proven monozygotic twins with the adult form of adrenoleukodystrophy with significant phenotypic heterogeneity. Myeloneuropathy was common to both patients, but cognitive impairment and affective symptoms with extensive demyelination in the brain were prominent in the older twin, while adrenal insufficiency was predominant in the younger twin. The younger twin, however, exhibited affective symptoms similar to those displayed by his elder twin 10 years later. These findings suggest that nongenetic factors are important in determining the phenotypic variation of adrenoleukodystrophy gene.

Claims other papers make about this one

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

  • The few studied monozygotic twins with X-ALD showed less discordant phenotypes.

    “Devastating childhood cALD and late adulthood AMN may co-exist within the same family [103,104,105,106], whereas the few studied monozygotic twins showed less discordant phenotypes [107,108,109,110].”

    From Revisiting the Pathogenesis of X-Linked Adrenoleukodystrophy (2025) · cites this paper as [108]

  • Reports of varying phenotypes in identical twins suggest that environmental factors may be involved in X-ALD phenotypic variation.

    “However, reports of varying phenotypes in identical twins suggest that environmental factors may be involved [Sobue et al., 1994;Korenke et al., 1996].”

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.
