Abstract

The neuronal ceroid lipofuscinoses (NCLs) constitute a group of neurodegenerative storage diseases characterized by progressive psychomotor retardation, blindness and premature death. Pathologically, there is accumulation of autofluorescent material in lysosome-derived organelles in a variety of cell types, but neurons in the central nervous system appear to be selectively affected and undergo progressive death. In this report we show that a novel form of NCL, congenital ovine NCL, is caused by a deficiency in the lysosomal aspartyl proteinase cathepsin D. A single nucleotide mutation in the cathepsin D gene results in conversion of an active site aspartate to asparagine, leading to production of an enzymatically inactive but stable protein. This results in severe cerebrocortical atrophy and early death, providing strong evidence for an important role of cathepsin D in neuronal development and/or homeostasis.

  • CTSD is a ubiquitous protease, but its unique importance in brain is illustrated by the relatively selective neurodevelopmental and progressive neurodegenerative phenotype induced by loss-of-function CTSD mutations causing CLN10.

    “CTSD is a ubiquitous protease, but its unique importance in brain is illustrated by the relatively selective neurodevelopmental and progressive neurodegenerative phenotype induced by the loss-of-function CTSD mutations causing the congenital disorder neuronal ceroid lipofuscinosis CLN10 (Tyynela ¨et al., 2000;Siintola et al., 2006).”

    From Lysosomal Dysfunction in Down Syndrome Is APP-Dependent and Mediated by APP-βCTF (C99) (2019) · cites this paper as Tyynela ¨et al., 2000

    The Results describe a loss-of-function cathepsin D mutation in sheep with severe brain pathology at birth, while other examined organs appeared macroscopically unaffected; the Discussion calls brain pathology the most striking feature. But this paper does not establish that CTSD mutations cause human CLN10: its Discussion says that whether congenital human NCL represents cathepsin D deficiency remains to be determined.

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.
