Scientific Questions Being Studied
To identify prostate cancer risk variants and genes in African American men. The reason for exploring this data is that prostate cancer develops more often in men of African ancestry than in men of other races. However, so far, prostate cancer genetic studies are based on the available data that mostly come from white men. This racial disparity has biased the discovery of genetic risk factors and therapeutic approaches, leading disparity in mortality rates
Project Purpose(s)
- Disease Focused Research (prostate carcinoma)
- Social / Behavioral
- Ancestry
Scientific Approaches
I will design a two matched case-control studies black and white men. Thereafter, conduct a GWAS to identify variants and genes with higher mutation frequency. Next, I will identify genes mutated with larger functional impact through functional annotation analyses. Will repeat analysis using rare variants which will include rare variant association tests
Anticipated Findings
I anticipate finding novel variants and confirming prostate cancer risk variants that are specific to men of African ancestry. Doing so will increase the representation of African American men in prostate cancer genomic studies and increase African American awareness of early detection screening protocols.

Scientific Questions Being Studied
Hypertension is one of the most common diseases in the US. Here, we will be determining what genetic variants contribute to higher systolic blood pressure, diastolic blood pressure, and pulse pressure in participants of African ancestry.
Project Purpose(s)
- Disease Focused Research (hypertension)
- Ancestry
Scientific Approaches
I plan to use median measurement values to determine median SBP, DBP, and PP. Then I plan to use the genetic data available and a GWAS run with Plink to determine which associations exist. This GWAS will be using quantitative data and thus will use linear regression.
Anticipated Findings
We anticipate replicating previously reported hypertension GWAS findings. In addition, since most hypertension GWAS are done in European ancestry, we expect to identify new variants associated with participants of African ancestry

Scientific Questions Being Studied
Prostate Adenocarcinoma (PRAD) is associated with 1 in 25 African American men deaths, compared to 1 in 45 White American men deaths. Genetic and societal factors may contribute to this racial disparity and our project aims to shed light in both factors. Our goals are to find ethnic specific risk factors using survey-based features and genetic risk factors using the genetic variants data.
Project Purpose(s)
- Disease Focused Research (prostate cancer)
- Population Health
- Educational
- Methods Development
- Ancestry
Scientific Approaches
To achieve our goals we will use statistical tests and state-of-the-art tools to compare case and control genomes in order to identify variants that appear disproportionally in cases and genes with heavy variant load in cases. Such tools include the Evolutionary Action method and the software packages EMMAX and ACAT, amongst others.
Anticipated Findings
We anticipate obtaining lists of candidate genes and their variants that drive PRAD in African American men and in White American men, which we will contrast and compare with the current knowledge (e.g. BRCA1, BRCA2, and HOXB13 genes). This work may provide new genetic targets that affect the development and progression of PRAD, especially amongst the African American men and reduce the racial disparity in genetic risk diagnosis.
