Abstract

SAP 90/PSD95‐a ssociated p rotein (SAPAP) family proteins are post‐synaptic density (PSD) components that interact with other proteins to form a key scaffolding complex at excitatory (glutamatergic) synapses. A recent study found that mice with a deletion of the Sapap3 gene groomed themselves excessively, exhibited increased anxiety‐like behaviors, and had cortico‐striatal synaptic defects, all of which were preventable with lentiviral‐mediated expression of Sapap3 in the striatum; the behavioral abnormalities were also reversible with fluoxetine. In the current study, we sought to determine whether variation within the human Sapap3 gene was associated with grooming disorders (GDs: pathologic nail biting, pathologic skin picking, and/or trichotillomania) and/or obsessive‐compulsive disorder (OCD) in 383 families thoroughly phenotyped for OCD genetic studies. We conducted family‐based association analyses using the FBAT and GenAssoc statistical packages. Thirty‐two percent of the 1,618 participants met criteria for a GD, and 65% met criteria for OCD. Four of six SNPs were nominally associated (P < 0.05) with at least one GD (genotypic relative risks: 1.6–3.3), and all three haplotypes were nominally associated with at least one GD (permuted P < 0.05). None of the SNPs or haplotypes were significantly associated with OCD itself. We conclude that Sapap3 is a promising functional candidate gene for human GDs, though further work is necessary to confirm this preliminary evidence of association. © 2008 Wiley‐Liss, Inc.

  • Rare variations in the SAPAP3 gene are associated with human disorders such as hair pulling.

    “The potential relevance of SAPAP3, in particular, to trichotillomania, is reinforced by the finding that rare variations in the SAPAP3 gene are associated with human disorders such as hair pulling.[23]”

    From Trichotillomania (hair pulling disorder) (2019) · cites this paper as [23]

  • A human genetics study found no association of SAPAP3 single nucleotide polymorphisms with OCD, but did find associations with grooming disorders such as pathologic skin picking, trichotillomania, and/or nail biting.

    “a recent human genetics study found no association of SAPAP3 single nucleotide polymorphisms with OCD, but did find associations with grooming disorders such as pathologic skin picking, trichotillomania, and/or nail biting 94.”
  • Pathological body care such as nail biting seems to be associated with SAPAP3 mutations.

    “Particularly pathological body care such as nail biting seems to be associated with SAPAP3 mutations [8].”

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.
