Abstract

Here we report whole exome sequencing (WES) on a cohort of 71 patients with persistently unresolved white matter abnormalities with a suspected diagnosis of leukodystrophy or genetic leukoencephalopathy. WES analyses were performed on trio, or greater, family groups. Diagnostic pathogenic variants were identified in 35% (25 of 71) of patients. Potentially pathogenic variants were identified in clinically relevant genes in a further 7% (5 of 71) of cases, giving a total yield of clinical diagnoses in 42% of individuals. These findings provide evidence that WES can substantially decrease the number of unresolved white matter cases. Ann Neurol 2016;79:1031–1037

  • The percentage of leukodystrophy cases without a specific diagnosis has been estimated to be 20-30%.

    “Nevertheless, the percentage of leukodystrophy cases without a specific diagnosis has been estimated to be 20–30% [7,39,40].”

    From Identification of a Novel Non-Canonical Splice-Site Variant in ABCD1 (2023) · cites this paper as [7]

    The Introduction estimates that nearly half of patients presenting with a possible leukodystrophy remain unresolved, rather than 20–30%. The Methods (Cohort description) also report 90 persistently unsolved cases among 191 identified cases, approximately 47%. (LLM, conf=0.87)

    Checked by a reasoning model — may be wrong.

  • NGS genetic testing, including gene panel testing, WES, or WGS, is the most successful approach for diagnosing rare diseases with the highest diagnostic yield.

    “NGS genetic testing, including gene panel testing, WES, or whole genome sequencing (WGS), is the most successful approach for diagnosing rare diseases with the highest diagnostic yield [7,37].”

    From Identification of a Novel Non-Canonical Splice-Site Variant in ABCD1 (2023) · cites this paper as [7]

    The Results and Discussion support WES as a useful diagnostic approach for patients with unresolved white matter abnormalities: it yielded clinical diagnoses in 42% of the study cohort and increased diagnoses beyond standard approaches. The Discussion explicitly says further research is needed to compare WES, WGS, and targeted panels, so the paper does not establish that NGS is the most successful approach or has the highest yield across rare diseases. Page numbers are not provided in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Genetic screening using next-generation sequencing is the most successful approach with the highest diagnostic yield in cases of underlying genetic disorders, such as CALD, and provides the fastest results.

    “Genetic screening using next-generation sequencing (NGS) is the most successful approach with the highest diagnostic yield in cases of underlying genetic disorders, such as CALD, and provides the fastest results [7,8].”

    From Identification of a Novel Non-Canonical Splice-Site Variant in ABCD1 (2023) · cites this paper as [7]

    The Discussion (page unavailable) reports that whole-exome sequencing would increase diagnoses by about 20% in a cohort with genetic white matter disorders. It does not establish that NGS has the highest diagnostic yield or provides the fastest results, and says comparative effectiveness needs further study. The cited passages do not establish the claim specifically for CALD. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Trio-WES has substantially increased the number of known leukodystrophies and improved diagnoses.

    “Trio-WES has substantially increased the number of known leukodystrophies and improved diagnoses [7,8,39].”

    From Identification of a Novel Non-Canonical Splice-Site Variant in ABCD1 (2023) · cites this paper as [7]

    The Abstract reports that trio-or-larger WES yielded clinical diagnoses in 42% of 71 previously unresolved patients, and the Discussion estimates an approximately 20% diagnostic increase when WES is added to standard approaches. The paper does not show that WES substantially increased the number of known leukodystrophies; its Results describe diagnoses involving genes already associated with those disorders. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In a previously reported cohort of 191 families with suspected leukodystrophy, 71 were persistently unsolved despite targeted molecular and enzymatic testing and 19 were lost to follow-up.

    “Previously, we reported on a cohort of 191 families with a suspected leukodystrophy, of which 71 were persistently unsolved despite targeted molecular and enzymatic testing and 19 were lost to follow‐up.1”

    From Genome sequencing in persistently unsolved white matter disorders (2020) · cites this paper as [1]

    The Methods (Cohort description; page not provided) report an initial 191 cases, of which 101 received diagnoses and 90 remained unsolved; 71 of the unsolved families had suitable samples for exome sequencing. The other 19 were excluded from that testing—not reported as lost to follow-up: nine obtained sequencing elsewhere, and ten lacked suitable samples despite collection attempts. (LLM, conf=0.90)

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.
