Abstract

Background and purpose: The clinical characteristics of colony stimulating factor 1 receptor ( CSF 1R) related adult‐onset leukoencephalopathy with axonal spheroids and pigmented glia ( ALSP ) have been only partially elucidated. Methods: Clinical data from CSF 1R mutation carriers who had been seen at our institutions or reported elsewhere were collected and analysed using a specific investigation sheet to standardize the data. Results: In all, 122 cases from 90 families with CSF 1R mutations were identified. The mean age of onset was 43 years (range 18–78 years), the mean age at death was 53 years (range 23–84 years) and the mean disease duration was 6.8 years (range 1–29 years). Women had a significantly younger age of onset than men (40 vs. 47 years, P = 0.0006, 95% confidence interval 3.158–11.177). There was an age‐dependent penetrance that was significantly different between the sexes ( P = 0.0013). Motor dysfunctions were the most frequent initial symptom in women whose diseases began in their 20s. Thinning of the corpus callosum, abnormal signalling in pyramidal tracts, diffusion‐restricted lesions and calcifications in the white matter were characteristic imaging findings of ALSP . The calcifications were more frequently reported in our case series than in the literature (54% vs. 3%). Seventy‐nine per cent of the mutations were located in the distal part of the tyrosine kinase domain of CSF 1R (102 cases). There were no apparent phenotype−genotype correlations. Conclusions: The characteristics of ALSP were clarified. The phenotype of ALSP caused by CSF 1R mutations is affected by sex.

  • A sex-difference in susceptibility has been reported in a Japanese cohort of HDLS associated with CSF1R mutations.

    “A sex-difference in susceptibility has been reported in a Japanese cohort of HDLS associated with CSF1R mutations [23].”

    From Loss of homeostatic microglial phenotype in CSF1R-related Leukoencephalopathy (2020) · cites this paper as [23]

    The Results (Clinical data; page unavailable) report a significant sex difference in age-dependent disease penetrance among CSF1R mutation carriers, supporting the susceptibility claim. The Methods (Study subjects and extracting data; page unavailable) identify 26 Japanese cases, but the reported sex-difference analysis used a larger set of cases that also included cases from the literature, so describing the finding as arising from a Japanese cohort alone is too narrow.

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.
