Abstract

DESCRIPTION (provided by applicant): Major depression is a serious psychiatric disorder impacting the lives of millions of Americans. The gene DISC1 has been linked to this disorder by translocation in a single Scottish family as well as being supported by functional analyses of the gene prominent in neural development. We propose to carry out whole genome sequencing on 40 members of the original translocation family to identify possible variants that modify the effec of the translocation on phenotype as well as examine epigenetic differences in those that bear the translocation. We will also carry out genetic analyses by both genotyping and targeted sequencing to look for genetic differences in DISC1 and its core pathway genes in a total of nearly 10,000 people. Lastly, we will examine blood samples from some of those individuals with variants in the core pathway to determine if these variants change gene expression.
