Abstract

While clinical and basic biomedical research focus on diagnoses and cures for common and rare genetic diseases, they are unable to address one of the largest underlying causes for genetic disease: mating within families or other small genetically isolated sub-populations. This interdisciplinary literature study investigates theoretical, moral and practical aspects to solve this major cause for genetic disease from an alternative angle: through cultural change and encouragement of an outbreeding reproductive behavior. Understanding why some communities persist with choosing consanguineous reproductive partners when the modern society has eliminated the economic rationale to do so, and to develop strategies to encourage a cultural change in those communities, is critical for a sustainable long-term solution to reduce the number of new cases of genetic disease and undiagnosed (sub-clinical) but detrimental genetic abnormalities in vulnerable and marginalized groups in modern Western societies.
