Definitions

  • Schizophrenia is a devastating psychiatric disease for which there is currently no cure, although advances are now being made in understanding its causes and controlling its symptoms. In general the age of onset is in late adolescence and it is a lifelong illness with a very poor prognosis. Subjects suffering from schizophrenia may exhibit positive symptoms, for example delusions and hallucinations, and /or negative symptoms such as withdrawal, isolation and demotivation leading ultimately to social decline and suicide. Early identification of subjects at risk of developing schizophrenia would enable early and if appropriate, prophylactic treatment to be given.
  • the step of testing for and detecting the presence or absence of DNA encoding the 10- and or 12-repeat alleles may be carried out either directly or indirectly by any suitable means, such as by techniques well known in the art, and is preferably carried out ex vivo All generally involve the step of collecting a sample of biological material containing DNA from the subject, and then detecting which alleles the subject possesses from that sample.
  • the detecting step may be carried out by collecting a biological sample containing DNA from the subject, and then determining the presence or absence of DNA comprising a 10- and/or 12-repeat allele in the biological sample.
  • Any biological sample which contains the DNA of that subject may be employed, including tissue samples and blood samples, with blood cells being a particularly convenient source.
  • the detecting step may include the step of detecting whether the subject is heterozygous or homozygous for the gene encoding a 10- and/or 12-repeat allele.
  • Numerous different oligonucleotide probe assay formats are known which may be employed to carry out the present invention.
  • the present invention has utility in enabling improvements in the clinical management of patients suffering from a psychotic disorder, such as schizophrenia, bipolar depression or unipolar depression.
  • a psychotic disorder such as schizophrenia, bipolar depression or unipolar depression.
  • the method used to detect the polymo ⁇ hism of the VNTR in the serotonin transporter hSERT was based on the method of Lesch et al. (J Neural Transm. 1994 95(2) 157-62) with the following modification: the oligonucleotide primers 5' gtcagtatcaacaggctgcgag 3' and 5' tgttcctagtcttacgccagtg 3' were used.
  • the size of the DNA PCR products after the use of these oligonucleotide primers was determined by a standard method ie electrophoresis in an agarose gel next to DNA size standards and then staining of the DNA with ethidium bromide and visualisation of the DNA under an ultraviolet li *geh* t.
  • the method used to detect the polymorphism of the VNTR in the serotonin transporter hSERT was based on the method of Lesch et al. (J Neural Transm. 1994 95(2) 157-62) with the following modification: the oligonucleotide primers 5' gtcagtatcacaggctgcgag 3' and 5' tgttcctagtcttacgccagtg 3' were used.
  • the size of the DNA PCR products after the use of these oligonucleotide primers was determined by a standard method ie electrophoresis in an agarose gel next to DNA size standards and then staining of the DNA with ethidium bromide and visualisation of the DNA under an ultraviolet light.
  • Genotyping for VNTR polymorphism was carried out using blood samples obtained from individuals diagnosed as suffering from unipolar and/or bipolar depression (DSM IV). Genotyping was also carried out on a control group of patients not suffering from unipolar and/or bipolar depression.

Abstract

L'invention porte sur une méthode utilisable lorsqu'il s'agit d'évaluer si un patient risque ou non de développer un trouble d'ordre psychotique, une schizophrénie, un trouble affectif bipolaire ou une dépression unipolaire, par exemple. La méthode consiste à rechercher la présence ou l'absence d'ADN codant les allèles à 10 répétitions et/ou à 12 répétitions de l'intron 2 VNTR sur le gène hSERT dans un échantillon biologique prélevé sur ce patient. Cette invention concerne également une lignée cellulaire et un animal transgénique exprimant les 10 et/ou 12 répétitions.
