(Submitter supplied) To identify genes dysregulated in bipolar disorder (BD1) we carried out global gene expression profiling using whole-genome microarrays. To minimize genetic variation in gene expression levels between cases and controls we compared expression profiles in lymphoblastoid cell lines from monozygotic twin pairs discordant for the disease. We identified 82 genes that were differentially expressed by ≥ 1.3-fold in 3 BD1 cases compared to their co-twins, and which were statistically (p ≤ 0.05) differentially expressed between the groups of BD1 cases and controls. more...

(Submitter supplied) Gene expression profiling in peripheral blood cells from monozygotic twin pairs with various sytemic autoimmune diseases revealed 92 genes that could discriminate between MZ twin pairs and unrelated-matched controls. No genes were found that could discriminate between proband and unaffected twin pairs, or between the various disease phenotypes.

(Submitter supplied) Objective: To identify genes involved in idiopathic absence epilepsies by analysing gene expression using a monozygotic (MZ) twin design. Methods: Genome-wide gene expression in lymphoblastoid cell lines was determined using microarrays derived from five discordant and four concordant MZ twin pairs with idiopathic absence epilepsies and five unaffected MZ twin pairs. Gene expression was analysed using three strategies: discordant MZ twins were compared as matched pairs, MZ twins concordant for epilepsy were compared to control MZ twins, and a singleton design of affected versus unaffected MZ twin individuals was used irrespective of twin pairing. more...

(Submitter supplied) Bipolar affective disorder is a severe psychiatric disorder with a strong genetic component but unknown pathophysiology. We used microarray technology (Affymetrix HG-U133A GeneChips) to determine the expression of approximately 22 000 mRNA transcripts in post-mortem brain tissue (dorsolateral prefrontal cortex and orbitofrontal cortex) from patients with bipolar disorder and matched healthy controls. more...

(Submitter supplied) Human intelligence demonstrates one of the highest heritabilities among human quantitative traits. Phenotypically discordant monozygotic twins provide a way to identify loci reponsible for the phenotypical differences. We performed comprehensive DNA methylation analysis in monozygotic twins manifesting differences in IQ scores. Genes with significantly different methylation status are considered as candidates related to human intelligence.

(Submitter supplied) Human intelligence demonstrates one of the highest heritabilities among human quantitative traits. Phenotypically discordant monozygotic twins provide a way to identify loci responsible for normal-range intelligence. We conducted array-based genome-wide gene expression analysis aiming to identify genes displaying significant difference among monozygotic twin pairs manifesting between-co-twins IQ differences.

(Submitter supplied) Background: The autism spectrum includes a set of complex multigenic developmental disorders that severely impact the development of language, non-verbal communication, and social skills, and are associated with odd, stereotyped, repetitive behavior and restricted interests. To date, diagnosis of these neurologically based disorders relies predominantly upon behavioral observations often prompted by delayed speech or aberrant behavior, and there are no known genes that can serve as definitive biomarkers for the disorders. more...

(Submitter supplied) Natural variation in gene expression among healthy human individuals has been largely unexplored. In order to understand the genetic basis of variation in gene expression between normal human individuals, we need to obtain genome-wide expression data from various populations. Studies in monozygotic twins could enable us to estimate the size of the contribution of genetic and environmental factors to the natural variation in gene expression. more...

(Submitter supplied) This data was divided into three experiment sets: 1. A somatic study of sporadic motor neuron disease (SMND) brain samples that were compared to the blood from the same individual, normal control brains and disease control brans (Parkinson Disease patients); 2. A twin study comparing blood and other tissue samples from twins that were discordant for MND, concordant for MND and control twins and 3. A trio study of blood samples MND patients compared to their unaffected parents.

(Submitter supplied) Short sleep duration is associated with adverse metabolic, cardiovascular, and inflammatory effects. Co-twin study methodologies account for familial (e.g., genetics and shared environmental) confounding, allowing assessment of subtle environmental effects, such as the effect of short habitual sleep duration on gene expression. Therefore, we sought to investigate gene expression in monozygotic twins discordant for actigraphically phenotyped habitual sleep duration. more...

(Submitter supplied) Researchers have long relied on gene expression changes identified in animal models to develop targeted therapy for traumatic brain injury (TBI), but so far these therapies have not proved effective in human trials. While these pre-clinical models have provided valuable mechanistic insights, they might not reflect the unique pathophysiology of concussion in humans. Identifying important and potentially modifiable gene expression changes in humans diagnosed with TBI can help facilitate effective therapies. more...
