Abstract

XRCC1 is a molecular scaffold protein that assembles multi-protein complexes involved in DNA single-strand break repair. Here we show that biallelic mutations in the human XRCC1 gene are associated with ocular motor apraxia, axonal neuropathy, and progressive cerebellar ataxia. Cells from a patient with mutations in XRCC1 exhibited not only reduced rates of single-strand break repair but also elevated levels of protein ADP-ribosylation. This latter phenotype is recapitulated in a related syndrome caused by mutations in the XRCC1 partner protein PNKP and implicates hyperactivation of poly(ADP-ribose) polymerase/s as a cause of cerebellar ataxia. Indeed, remarkably, genetic deletion of Parp1 rescued normal cerebellar ADP-ribose levels and reduced the loss of cerebellar neurons and ataxia in Xrcc1-defective mice, identifying a molecular mechanism by which endogenous single-strand breaks trigger neuropathology. Collectively, these data establish the importance of XRCC1 protein complexes for normal neurological function and identify PARP1 as a therapeutic target in DNA strand break repair-defective disease.

  • High levels of nuclear DNA damage lead to prolonged PARP1 activation, which consumes large amounts of NAD+.

    “High levels of nuclear DNA damage, e.g. in cells from aged organisms or DNA repair mutants, lead to prolonged activation of PARP1, a DNA break sensor that upon activation consumes large amounts of NAD+60.”

  • The majority of DNA damage disorders typically present in early childhood, with the exception of AOA5.

    “With the exception of AOA5, which seems to have manifested exclusively in adults so far (Hoch et al, 2017: 1; O’Connor et al, 2018: 1), the majority of DNA damage disorders typically present in early childhood.”

  • Mutations in XRCC1 cause Ataxia with Oculomotor apraxia Type 5 (AOA5).

    “Defective XRCC1 manifests in individuals as Ataxia with Oculomotor apraxia Type 5 (AOA5), another slow‐progressing neurodegenerative disease.”

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.
