Genetic variations that underlie common autoimmune disease genes are predominantly regulatory and modify the expression of multiple genes within the HLA gene complex and throughout the immune system.
Genetic predisposition to uterine leiomyomas arises from variation at loci for genetic stability and genitourinary development, and in part explains the frequent occurrence of the condition in women with African origin.
Increasing levels of glucose-6-phosphate dehydrogenase deficiency are associated with decreasing risk of cerebral malaria, but with increased risk of severe malarial anaemia.
Natural variation for an adaptively important life history trait is largely due to variation at a single, major-effect locus with multiple alleles, demonstrating that not all complex traits are massively polygenic.
Lipid efflux by the retinal pigment epithelium is crucial for proper retinal integrity and function, and its impairment may contribute to diseases like age-related macular degeneration.
The Mediterranean variant of glucose-6-phosphate dehydrogenase deficiency confers a strong gene-dose proportional protective effect against symptomatic Plasmodium vivax malaria in the Pashtun ethnic group.
Bulk whole genome sequencing data can be used to study the genetic variation present in pathogenic bacterial populations over the time-course of a single infection within a host.
