The focus of research in the Raskind laboratory is to identify and study genes responsible for human inherited disorders, both simple and complex. We investigate a variety of neurogenetic disorders, including spastic paraparesis, myokymia, paroxysmal chorea, and ataxias. Probands are ascertained, families are recruited and linkage analyses are carried out. After mapping the location and narrowing the interval containing the gene, candidates are prioritized and evaluated to identify the gene responsible for the disease. Recently, we have discovered that mutations in a serine/threonine kinase gene, protein kinase C gamma, are responsible for an autosomal dominant spinocerebellar ataxia (SCA14). As part of a broad approach to understanding this disease, in-vitro functional assays and creation of mouse models are underway.

In addition to diseases that are inherited in a simple Mendelian fashion, behavioral disorders that have complex inheritance patterns are studied. In particular, as part of the UW Multidisciplinary Learning Disabilities Center, we are investigating the genetics of dyslexia and related learning disabilities. The targeted phenotypes are based on performance on tests that evaluate reading, writing and spelling ability, as well as those that assess executive function. Multigenerational families are being studied to characterize, model and map genetic subtypes of dyslexia.
