The Impact of Genomic Diversity on Medical Advances

Genetics is a fascinating field that has enabled us to understand the inheritance Patterns of various traits and diseases. While we have made significant progress in unraveling Mendelian genetics, there is still much to explore when it comes to polygenic diseases and the role of artificial intelligence (AI). However, the field of genomics is currently facing a crisis of genomic diversity, which has far-reaching implications for medical advances and personalized medicine.

Mendelian genetics, characterized by dominant and recessive alleles, follow specific inheritance patterns that we have successfully identified. This allows us to predict the likelihood of certain diseases Based on an individual's genetic makeup. AI has played a crucial role in the identification of disease-causing genes and the prediction of disease risk, especially in cases of monogenic disorders.

However, the majority of diseases of interest today are polygenic diseases, which are caused by the combined action of multiple genes. These diseases, such as obesity, heart disease, and certain types of cancers, require a deeper understanding of the complex interactions between genes. This is where AI can truly shine by mapping out intricate connections between genes and diseases.

The crisis arises from the fact that most genomic studies and data sets are heavily biased towards individuals of European descent. This bias is evident in the UK Biobank, one of the largest genomic studies, which primarily includes samples from individuals of European ancestry. Such biased data sets hinder the development of accurate polygenic disease models that work across diverse populations.

Commercial genetic testing services, like ancestry.com, also contribute to the problem of data bias. While they provide detailed results for individuals of East African, West African, and European descent, those with East Asian or Native American ancestry receive limited information. This bias Stems from the skewed data sets used to generate their models, which predominantly represent European and East African ancestries.

The consequences of data bias become particularly concerning when it comes to drug dosing. Warfarin, a blood thinner, is dosed based on a machine learning model. However, the dataset used to train this model is primarily composed of individuals of European descent, resulting in accurate dosing for this population but not for others. This highlights the urgent need for diverse data sets in order to provide equitable healthcare solutions.

Creating more diverse genomic data sets is crucial for overcoming these challenges. Research has shown that funding diverse researchers who have connections in underrepresented regions can lead to more inclusive data sets. However, one additional challenge is that individuals of Eastern African descent have some of the most diverse genomes in the world. To build accurate machine learning models, we need to Collect more data from these populations, which can be both costly and time-consuming.

Despite these challenges, the field of genomics is beginning to acknowledge the diversity crisis and take steps towards inclusivity. Recent projects and increased funding focus on building diverse genomic data sets to ensure that medical advances are distributed equally and fairly across the globe.

In conclusion, the impact of genomic diversity cannot be underestimated in the field of medical advances. From Mendelian genetics to polygenic diseases, AI plays a critical role in understanding the complex interplay between genes and diseases. However, the lack of diverse genomic data sets hinders our ability to develop accurate models and tailored treatments for all populations. Acknowledging and addressing the crisis of genomic diversity is essential to creating a future of equitable healthcare and precision medicine.
