Current Research Interests:

Genes of Brain Disorders

After the Human Genome was characterized end of last century, now the decade of the brain has arrived. We are using genetic information to find the genes involved in brain disorders, then dissect the disease process, often in animal models. We have identified deafness and other neurological disorder genes and now focus on ataxias as well as behavior and psychiatric diseases.

There are at least 60 known ataxia genes, some of which our lab discovered. Our pipeline starts with recruitment of families with rare disorders, then combines genetic (linkage) information with genome-wide gene expression and next generation sequencing. By combining these approaches, we could identify genes involved in ataxias, and are actively recruiting additional families with rare neurological disorders.

Human behavior and risk for psychiatric illness such as depression and alcoholism are determined by a complex interaction of environmental and multiple genetic risk factors. With the Human Genome sequenced, unprecedented numbers of genetic variants identified, and novel technologies that allow the study of genetic variants, untangling these risk factors is now possible, using genome-wide association studies (GWAS) and next generation sequencing. For most complex disorders, considering the environment as well as the genetic susceptibility is essential to fully understand their function.

In addition to genetic risk factors for bipolar disorder and for addiction, we also investigate genetic variants that influence traits related to psychiatric disorders: High anxiety or feeling vulnerable (neuroticism) is a marker for depression risk, and high impulsivity and low executive function are risk factor for addictions. These and other endophenotypes such as neuroimaging processes in the brain start explaining the path from genetic variant to behavioral outcome.

We collaborate with clinicians, psychologists, epidemiologists, statisticians and bioinformaticians as well as other geneticists in these endeavors.

Figure 2: Multiple risk factors for depression

Depression is thought to be caused by a combination of genetic factors, early experiences and stressful life events. Instead of comparing depressed subjects and controls, research on the genetics of personality can get at genetic predisposition genes for depression even while studying a general population sample.

Figure 3: Psychiatric disorders overlap and might be extremes of personality traits.

Genetic vulnerabilities for psychiatric disorders are shown as emerging from the extreme end of normal population variations of personality, illustrated as different background shades of mood, anxiety, cognitive processing and volition. Genetic factors affecting levels of these underlying traits, in interaction with additional genetic and environmental factors, can lead to psychiatric disorders shown here are bipolar disorder, schizophrenia, depression and anxiety disorders the symptoms and genetic risk factors of which are in part unique and in part overlapping. Because not all disorders can be covered in two dimensions, interactions and overlaps exist in many more dimensions than can be represented here.
