Trans-ancestry genome-wide association meta-analysis of prostate cancer identifies new susceptibility loci and informs genetic risk prediction

…, M Borre, WJ Blot, W Zheng, ED Yeboah, JE Mensah… - Nature …, 2021 - nature.com
Prostate cancer is a highly heritable disease with large disparities in incidence rates across
ancestry populations. We conducted a multiancestry meta-analysis of prostate cancer …

Characterizing prostate cancer risk through multi-ancestry genome-wide discovery of 187 novel risk variants

…, M Borre, WJ Blot, W Zheng, ED Yeboah, JE Mensah… - Nature …, 2023 - nature.com
The transferability and clinical value of genetic risk scores (GRSs) across populations remain
limited due to an imbalance in genetic studies across ancestrally diverse populations. Here …

Evidence of novel susceptibility variants for prostate cancer and a multiancestry polygenic risk score associated with aggressive disease in men of African ancestry

…, B Adusei, S Mante, A Darkwa-Abrahams, JE Mensah… - European urology, 2023 - Elsevier
Background Genetic factors play an important role in prostate cancer (PCa) susceptibility.
Objective To discover common genetic variants contributing to the risk of PCa in men of African …

TMPRSS2:ERG Gene Fusions in Prostate Cancer of West African Men and a Meta-Analysis of Racial Differences

…, A Truelove, J Welsh, JE Mensah… - American journal of …, 2017 - academic.oup.com
The prevalence of fusions of the transmembrane protease, serine 2, gene (TMPRSS2) with
the erythroblast transformation-specific–related gene (ERG), or TMPRSS2:ERG, in prostate …

[HTML][HTML] Testing the generalizability of ancestry-specific polygenic risk scores to predict prostate cancer in sub-Saharan Africa

…, H Diop, M Ndoye, NY Snyper, B Adusei, JE Mensah… - Genome biology, 2022 - Springer
Background Genome-wide association studies do not always replicate well across populations,
limiting the generalizability of polygenic risk scores (PRS). Despite higher incidence and …

Validation of a multi-ancestry polygenic risk score and age-specific risks of prostate cancer: A meta-analysis within diverse populations

…, B Adusei, S Mante, A Darkwa-Abrahams, JE Mensah… - Elife, 2022 - elifesciences.org
Background: We recently developed a multi-ancestry polygenic risk score (PRS) that
effectively stratifies prostate cancer risk across populations. In this study, we validated the …

Evaluating approaches for constructing polygenic risk scores for prostate cancer in men of African and European ancestry

…, KD Sørensen, WJ Blot, ED Yeboah, JE Mensah… - The American Journal of …, 2023 - cell.com
Genome-wide polygenic risk scores (GW-PRSs) have been reported to have better predictive
ability than PRSs based on genome-wide significance thresholds across numerous traits. …

[HTML][HTML] Circulating trans fatty acids are associated with prostate cancer in Ghanaian and American men

…, Y Tettey, RB Biritwum, AA Adjei, JE Mensah… - Nature …, 2023 - nature.com
The association between fatty acids and prostate cancer remains poorly explored in African-descent
populations. Here, we analyze 24 circulating fatty acids in 2934 men, including …

[HTML][HTML] Genetic signatures of gene flow and malaria-driven natural selection in sub-Saharan populations of the" endemic Burkitt Lymphoma belt"

…, TP Leal, MD Ogwang, ED Yeboah, JE Mensah… - PLoS …, 2019 - journals.plos.org
Populations in sub-Saharan Africa have historically been exposed to intense selection from
chronic infection with falciparum malaria. Interestingly, populations with the highest malaria …
