Abstract

Mutations in UBQLN2 encoding ubiquilin-2 have recently been identified in families with dominant X-linked juvenile and adult-onset amyotrophic lateral sclerosis (ALS) and ALS/dementia. Ubiquilin-2 is a component of the ubiquitin inclusions detected in degenerating neurons in ALS patients. All the previously reported UBQLN2 mutations were localized in 1 of the 12 PXX domains of ubiquilin-2 protein. We sequenced UBQLN2 in 130 French patients with familial ALS (FALS) and absence of male-to-male transmission and the PXX domain in 240 more patients with sporadic ALS (SALS). We identified, at the heterozygote state, the c.1500_1508delCATAGGCCC, p.Gly502_Ile504del, in 1 affected woman. This deletion presumably leads to the in-frame deletion of 1 PXX repeat in the protein. This variant did not segregate with the disease in the corresponding family and was also detected in 1/380 control subject. Our results suggest that UBQLN2 gene mutations are rare in French ALS.

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.
