Haplotype-based inference of hidden structure in the human genome

Project description

Unlocking structural insights of the human genome

While modern genomic sequencing technologies are revolutionising medical research, their practical application is currently limited by a lack of effective data analysis techniques. Supported by the Marie Skłodowska-Curie Actions programme, the BENEFITTING project aims to address these limitations by introducing advanced haplotype-based statistical methods that will unlock biological insights from complex genomic data. It will develop integrated approaches for analysing low-coverage and long-read sequencing data, with a particular focus on probabilistic haplotype-based methods for structural variant genotyping, imputation and analysis in large-scale population studies.

Objective

The rapid emergence of high-throughput genomic technologies—such as low-coverage sequencing (LCS), ancient DNA (aDNA), and long-read sequencing (LRS)—offers unprecedented opportunities to explore human evolutionary history and advance medical genetics. However, the full potential of these data remains underexploited due to analytical and methodological limitations: for example, low coverage aDNA (<0.5x) is typically excluded ancestral recombination graph (ARG) analyses, while low structural variant (SV) genotyping accuracy and the lack of reliable imputation panels limit population-scale association studies.

This project proposes the development of two innovative haplotype-based statistical methods to overcome these barriers and unlock novel biological insights. First, I will establish a unified framework that integrates ARG construction with genotype imputation, enabling robust large-scale genealogical and demographic analyses of both modern and ancient low-coverage genomes. Second, I will develop a probabilistic haplotype-based approach for structural variant (SV) genotyping and imputation with long-read sequencing data, applying it to large population cohorts. These methods will be validated on cutting-edge resources, including the UK Biobank and the Allen Ancient DNA Resource, and disseminated through open-source software.

By bridging methodological gaps in aDNA and SV analyses, this project will deliver tools for demography inference using ARGs, SV-informed trait mapping, and the integration of diverse genomic data in population and medical genomics. The first application of the tools will have profound impacts. The unlocked high-resolution human history will contribute to public discourse on the definition and biomedical use of genetic ancestry. Discoveries of disease-associated SVs and underlying biological mechanisms will inform drug development, personalized treatment, and supporting industrial innovation.
