SQSTM1 mutations – Bridging Paget disease of bone and ALS/FTLD

Rea, Sarah L., Majcher, Veronika, Searle, Mark S., Layfield, Rob·2014·Experimental Cell Research

Abstract

Paget disease of bone (PDB) is a skeletal disorder common in Western Europe but extremely rare in the Indian subcontinent and Far East. The condition has a strong genetic element with mutations affecting the SQSTM1 gene, encoding the p62 protein, frequently identified. Recently SQSTM1 mutations have also been reported in a small number of patients with amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), neurodegenerative disorders in which significant coexistence with PDB has not been previously recognized. Although several SQSTM1 mutations are common to both ALS/FTLD and PDB, many are ALS/FTLD-specific. The p62 protein regulates various cellular processes including NF-κB signaling and autophagy pathways. Here we consider how knowledge of the impact of PDB-associated SQSTM1 mutations (several of which are now known to be relevant for ALS/FTLD) on these pathways, as well as the locations of the mutations within the p62 primary sequence, may provide new insights into ALS/FTLD disease mechanisms.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • SQSTM1 mutations are a rare cause of ALS-FTD, accounting for ~1-3.5% of cases with or without family history, and also cause Paget's disease of bone and inclusion body myositis.

    “SQSTM1 mutations are not only a rare cause of ALS-FTD, accounting for ~1-3.5% of cases with or without family history [123–125], but also Paget’s disease of bone (PDB), a chronic and progressive skeletal disorder characterized by disorganized bone turnover [126,127], and inclusion body myositis (IBM) [128].”

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.
