Abstract

The molecular mechanisms driving the biological clock in the suprachiasmatic nucleus of the hypothalamus may play a role in mood disorders. A single nucleotide polymorphism (SNP) (-50 T/C) falling into the effective promoter region (nt -171 to +29) of the gene coding for glycogen synthase kinase 3-beta (GSK3-beta) has been linked with different age at onset of bipolar illness and with different antidepressant effects of total sleep deprivation. GSK3-beta codes for an enzyme which is a target for the action of lithium and possibly of valproic acid. We studied the effect of this polymorphism on the therapeutic response to lithium salts of 88 bipolar type I patients. Data about recurrence rate of mood episodes were collected for at least 2 years before lithium and 2 years on lithium. Results showed that homozygotes for the wild variant did not change their recurrence index while carriers of the mutant allele improved, thus supporting the hypothesis that GSK is a target for the therapeutic action of lithium. Results warrant interest for the variants of genes pertaining to the molecular clock as possible endophenotypes of bipolar disorder, but caution ought to be taken in interpreting these preliminary results and future replication studies must be awaited because of the low frequency of the GSK3-beta*C/C genotype in the studied populations.

  • The GSK3β −50 T to C SNP is linked to a later age of onset of bipolar disorder.

    “one of these SNPs (−50 T to C) is linked to a later age of onset of BPD and a greater response to total sleep deprivation (TSD) and long-term lithium treatment (Benedetti et al., 2004; Benedetti et al., 2005).”

  • Other studies failed to show a general association between the GSK3β SNPs and bipolar disorder.

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.
