MorPhiC Consortium: towards functional characterization of all human genes

Abstract

Recent advances in functional genomics and human cellular models have substantially enhanced our understanding of the structure and regulation of the human genome. However, our grasp of the molecular functions of human genes remains incomplete and biased towards specific gene classes. The Molecular Phenotypes of Null Alleles in Cells (MorPhiC) Consortium aims to address this gap by creating a comprehensive catalogue of the molecular and cellular phenotypes associated with null alleles of all human genes using in vitro multicellular systems. In this Perspective, we present the strategic vision of the MorPhiC Consortium and discuss various strategies for generating null alleles, as well as the challenges involved. We describe the cellular models and scalable phenotypic readouts that will be used in the consortium's initial phase, focusing on 1,000 protein-coding genes. The resulting molecular and cellular data will be compiled into a catalogue of null-allele phenotypes. The methodologies developed in this phase will establish best practices for extending these approaches to all human protein-coding genes. The resources generated-including engineered cell lines, plasmids, phenotypic data, genomic information and computational tools-will be made available to the broader research community to facilitate deeper insights into human gene functions.

The schematics show general experimental strategies for null allele generation and main cellular and molecular assays to characterize phenotypes of null alleles. The figure was originally created by Daryl Leja and modified by Mazhar Adli. Circled numbers indicate DPCs.

The schematics compare the main experimental strategies the MorPhiC team will use for null allele generation. * There may be cases where all isoforms may be degron tagged, or degron may critically alter the gene function
