Examination Of Common And Rare Variant Genetic Architecture Of Psychiatric Disorders, Mohammad Ahangari
Examination Of Common And Rare Variant Genetic Architecture Of Psychiatric Disorders, Mohammad Ahangari
Theses and Dissertations
Psychiatric disorders are often heterogenous in their manifestation and genome-wide association studies have identified many common risk variants involved in their polygenic architectures with varying degrees of pleiotropy. In recent years, large-scale biobanks have also begun sequencing the genome of their participants to elucidate the role of rare risk variation in the genetic architecture of complex phenotypes, including psychiatric traits. This dissertation sought to better understand the role of both common and rare risk variation in the genetic architecture of psychiatric disorders with a particular focus on schizophrenia and alcohol problems. In the first three analyses, we focused on characterizing …
Exploring The Heteromeric Interface Of The 5-Ht2a-Mglu2 Receptor Complex, Mohamed Aarif Abdul Kareem
Exploring The Heteromeric Interface Of The 5-Ht2a-Mglu2 Receptor Complex, Mohamed Aarif Abdul Kareem
Theses and Dissertations
Schizophrenia is a serious mental disorder characteristic of several neurotransmitters including dopamine, serotonin, and glutamate being in imbalance. Early therapies focused solely on dopamine antagonism and second-generation antipsychotics focused on the dopamine and serotonin systems and their respective G protein coupled receptor (GPCR) proteins. Although debate for dimerization of certain classes of GPCR exist, the establishment of an mGlu2-5-HT2A heterocomplex, which is implicated in schizophrenia is of interest. Previous studies have used a mutation-based approach to identify transmembrane domain 4 (TM4) as the domain responsible in mGlu2 for mediating heteromerization before narrowing down the individual amino acids responsible for …
A Study Of Media Portrayal Of Schizophrenics To Understand How Stigma Associated With Schizophrenia May Be Reversed, Rainielle M. Cua
A Study Of Media Portrayal Of Schizophrenics To Understand How Stigma Associated With Schizophrenia May Be Reversed, Rainielle M. Cua

The news media are one of the most influential sources of information regarding mental illness. Media coverage on schizophrenia, one of the most stigmatized mental illnesses, tends to be negative, focusing on high risks of violence, failure, and unpredictability. Such perceptions may cause a detrimental impact on the mentally ill and cause them to internalize a stigmatizing stereotype and hinder the public’s understanding of mental illness. I studied how media portrayal in newspaper coverage of schizophrenics has evolved to discover how nonfiction media representation has affected people’s perceptions and attitudes towards schizophrenics and to propose an implementable solution to reduce …
Identifying Functional Variation In Schizophrenia Gwas Loci By Pooled Sequencing, Erik Loken
Identifying Functional Variation In Schizophrenia Gwas Loci By Pooled Sequencing, Erik Loken
Theses and Dissertations
Schizophrenia demonstrates high heritability in part accounted for by common simple nucleotide variants (SNV), rare copy number variants (CNV) and, most recently, rare SNVs Although heritability explained by rare SNVs and CNVs is small compared to that explained by common SNVs, rare SNVs in functional sequences may identify specific disease mechanisms. However, current exome methods do not capture a large proportion of potentially functional bases where rare variation may impact disease risk: as much as two-thirds of conserved sequences lie outside the exome in non-coding regions of cross-species evolutionary constraint. We reasoned that the candidate loci from the Psychiatric Genomics …
