Genetics of Asthma: Insights From Genome Wide Association Studies (2021)
Book Chapter
Cooper, R. M., Bingham, K., Portelli, M. A., & Sayers, I. (2022). Genetics of Asthma: Insights From Genome Wide Association Studies. In Encyclopedia of Respiratory Medicine (308-325). (Second Edition). Elsevier. https://doi.org/10.1016/B978-0-08-102723-3.00155-4

Asthma is a heterogeneous respiratory disease that can be influenced by genetic and environmental factors leading to disease susceptibility and progression. Genome-wide association studies (GWAS) of asthma have yielded replicated findings and identif... Read More about Genetics of Asthma: Insights From Genome Wide Association Studies.

Pharmacogenetics of Asthma (2015)
Book Chapter
Fenech, A. G., Sayers, I., & Portelli, M. A. (2015). Pharmacogenetics of Asthma. In G. Grech, & I. Grossman (Eds.), Preventive and Predictive Genetics: Towards Personalised Medicine (241-274). Cham: Springer. https://doi.org/10.1007/978-3-319-15344-5_9

The study of pharmacogenetics has expanded from what were initially casual drug response observations present in families, to a fully-fledged science with direct therapeutic applications, within a timespan of less than 60 years. Within the field of a... Read More about Pharmacogenetics of Asthma.

Identification of a novel regulatory mechanism for the disease associated protein, uPAR (2014)
Journal Article
Portelli, M. A., Hall, I. P., & Sayers, I. (2014). Identification of a novel regulatory mechanism for the disease associated protein, uPAR. Malta Medical Journal, 26(1), 32-37

Expression quantitative trait loci (eQTLs), as determined through a series of statistical association studies collectively known as genome-wide association (GWA) studies, have provided us with a hypothesis free approach for the investigation into reg...
