Project description:Copy number variants (CNVs) represent a substantial source of genomic variation in vertebrates, but the zebrafish reference genome has no annotated CNV information. We developed a zebrafish CNV map using 80 zebrafish genomes from laboratory strains (AB, Tubingen, and WIK) and one native population, identifying 6,080 CNV elements. Overlapping or adjacent CNVs account for 14.6% of the genome, representing four times the CNV levels from other vertebrates including humans. Highest intra-specific CNV levels were observed for Tubingen, a common laboratory strain due to high fecundity. Tubingen variation likely represents higher initial population size and composite population founders initiating the laboratory strain. Extensive zebrafish CNVs, along with associated phenotypic impacts, advocates for increased usage of isogenic strains for genetic studies intended for human disease translation.

Project description:Genetic variation governs protein expression through both transcriptional and post-transcriptional processes. To investigate this relationship, we combined a multiplexed, mass spectrometry-based method for protein quantification with an emerging mouse model harboring extensive genetic variation from 8 founder strains. We collected genome-wide mRNA and protein profiling measurements to link genetic variation to protein expression differences in livers from 192 diversity outcross mice. We observed nearly 3,700 protein-level quantitative trait loci (pQTL) with an equal proportion of proteins regulated directly by their cognate mRNA as uncoupled from their transcript. Our analysis reveals an extensive array of at least five models for genetic variant control of protein abundance including direct protein-to-protein associations that act to achieve stoichiometric balance of functionally related enzymes and subunits of multimeric complexes.
