At present, the cost of genotyping single nucleotide polymorphisms (SNPs) in large numbers of subjects poses a formidable problem for molecular genetic approaches to complex diseases. We have tested the possibility of using primer extension and denaturing high performance liquid chromatography to estimate allele frequencies of SNPs in pooled DNA samples.(More)
BACKGROUND Prenatal and early postnatal exposure to maternal depression may "program" childhood behavior via epigenetic processes such as DNA methylation. Methylenetetrahydro-folate reductase (MTHFR) is an important enzyme in the generation of methyl groups for DNA methylation. The common MTHFR C677T variant is associated with depression in men and(More)
Discussions about genetic contributions to medical illness have become increasingly commonplace. Physicians and other health-care providers in all quarters of medicine, from oncology to psychiatry, routinely field questions about the genetic basis of the medical conditions they treat. Communication about genetic testing and risk also enter into these(More)
AIM There has been increasing interest in the concept of applying genetic counselling to psychiatric disorders, but despite its relevance to psychiatric illness, and interest from the target group, there have been no empiric investigations of psychiatric genetic counselling. In a population of unaffected parents of individuals with first episode as well as(More)
People with psychiatric disorders and their family members have expressed interest in receiving genetic counseling (GC). In February 2012, we opened the first (to our knowledge) specialist psychiatric GC clinic of its kind, for individuals with non-syndromic psychiatric disorders and their families. Prior to GC and at a standard 1-month follow-up session,(More)
Schizophrenia is a common disorder that may frequently be encountered when taking family histories in the genetics clinic, whether or not the referral is for a psychiatric indication. Like in other common disorders, the provision of recurrence risks for schizophrenia is a complex clinical issue because empiric recurrence risks (while reasonably well(More)
Genetic counseling is an important clinical service that is routinely offered to families affected by genetic disorders or by complex disorders for which genetic testing is available. It is not yet routinely offered to individuals with serious mental illnesses and their families, but recent findings that beliefs about the cause of mental illness can affect(More)
OBJECTIVE psychiatric disorders are profoundly stigmatized conditions. Many groups of healthcare professionals harbor negative attitudes towards affected individuals, which may interfere with the healthcare relationship, but genetic counselors' attitudes towards individuals with psychiatric disorders have not been investigated. Thus, we conducted an(More)
Recent studies have shown that individuals with schizophrenia and their family members are interested in genetic counseling, but few have received this service. We conducted an exploratory, retrospective study to describe (a) the population of individuals who were referred to the BC provincial medical genetics program for genetic counseling for a primary(More)
Schizophrenia is a common complex disorder characterized by psychosis, cognitive dysfunction and negative symptoms, whose etiology involves interactions between both genetic and environmental vulnerability factors. Recently, ongoing research attempting to elucidate the nature of these vulnerability factors has been generating exciting findings. The advances(More)
