The article overall provides a good summary of the paper, but the headline is rather misleading. The paper is not about diabetes, heart disease or schizophrenia, these are just examples of common conditions for which polygenic scores were generated. The genetic contribution to common diseases is quite variable, and even someone with a high genetic risk may still have a low absolute risk. The fact that most people carry 1-3 rare pathogenic variants linked with monogenic conditions is far more noteworthy and potentially more important for people's health, particularly in places where secondary findings are fed back or genomic screening is being implemented. The most important message of the paper is that genetic variation is universal, regardless of health status.
