Phd project in “Single cell genomic approaches to study mitochondrial genetics and disorders”
Mitochondria are central to numerous physiological processes and are unique organelles that carry their own genome, often in high copy number, encoding a subset of proteins, transfer RNAs, and ribosomal RNAs essential to their function. Germline inherited mitochondrial DNA (mtDNA) mutations are a major cause of human disease and hundreds of point mutations and deletions have been associated with a variety of overlapping phenotypes, estimated to affect ~1 in 4,300 individuals, placing them among the most common inherited metabolic disorders. Mitochondrial diseases are characterized by remarkable heterogeneity and while variable heteroplasmy (fraction of mitochondrial genomes carrying a variant) of associated pathogenic mutations/deletions may present a natural modulator of disease severity, many syndromes include cell-type specific phenotypes. Moreover, the accumulation of somatic mtDNA mutations has been associated with ageing phenotypes and malignancies. However, establishing genotype-phenotype correlations on a cellular and molecular level has been challenging due to the unique nature of mitochondrial genetics that include variant heteroplasmy as a dynamic variable, but also tissue-dependent differences in mtDNA copy number, its cell cycle-independent turnover and the uncertainty about rates and mechanisms underlying accumulation of somatic variants. To bridge this gap, we develop and apply single cell multi-omic technologies to enable the linkage of an individual cells’ mtDNA genotype to its phenotype, such as its gene expression, protein expression and/or chromatin accessibility profile to enhance our understanding of mitochondrial genetics and underlying human disease. In particular, we are interested to understand adaptive genomic and cellular responses to high levels of pathogenic mtDNA or an increased mutational burden in cellular and animal models, including primary patient specimens.
