MalariaGEN Network – Pf3k

Objectives

The project’s primary goal is to undertake a comprehensive analysis of genome variation in 3,000 parasite samples representing the major malaria-endemic regions of the world.

Specific objectives:

  • Provide an open set of P. falciparum genome sequence data that captures common variation across multiple populations in different parts of the world
  • Use a combination of short- and long-read sequencing technologies in controlled settings to establish standards for accuracy and completeness in the inference of P. falciparum genome sequence variation and to characterise the quality of information obtained from standard approaches
  • Combine information from read-mapping, full de novo assembly, variant assembly and iterative reassembly of specific genes to obtain the most comprehensive resource on P. falciparum variation to date
  • Develop new high-quality reference genomes that will increase the resolution and accuracy of variation analysis across the whole sample set
  • Analyse the data to learn about parasite population structure, epidemiology and history, mutational and recombinational processes generating diversity, evolutionary processes including drug resistance and immune evasion, and how such phenomena differ between populations and regions

The primary output of the project will be an open access data resource with companion publications on genomic diversity and population genetics that together provide a detailed description of P. falciparum genome variation across the major malaria-endemic regions.

Other outputs will include papers on methodology and standardisation of protocols for P. falciparum sequence analysis and genotyping calling. All of the underlying data will be made publicly available for use by the scientific community, initially under Fort Lauderdale conditions.

Rationale and Abstract

Pf3k is an international collaboration using the latest sequencing technologies to provide a high-resolution view of natural variation in the malaria parasite Plasmodium falciparum.

This is a collaborative project, a list of all the partners can be found online: https://www.malariagen.net/projects/Pf3k

Data

The Project will publicly release data on a regular basis and prior to publication. Raw sequence reads will be deposited in either the European Nucleotide Archive (ENA) or the NCBI. Alignments and variant calls will be released on individual samples, and data formats and software developed by the Project will be made publicly available. Associated sample information will be made available in the public domain through the MalariaGEN website and other public databases as appropriate. Public release of the data will be associated with contact information for the lead investigators that have contributed the samples.

At the time of their release, these data were subject to the Pf3k Pilot Phase Terms of Use. In September 2016, these restrictions were lifted and this dataset is now available open access.

Study Design

The primary output of the project will be an open access data resource with companion publications on genomic diversity and population genetics that together provide a detailed description of P. falciparum genome variation across the major malaria endemic regions.

Other outputs will include papers on methodology and standardisation of protocols for P. falciparum sequence analysis and genotyping calling. All of the underlying data will be made publicly available for use by the scientific community, initially under Fort Lauderdale conditions.
