VectorBase The Anopheles gambiae data and its display on Ensembl Genomes are made possible through a joint effort by the Ensembl Genomes group and VectorBase, a NIAID Bioinformatics Resource Center. The source data for this genome and other resources can be accessed via the VectorBase browser.

About Anopheles gambiae

Anopheles gambiae senso stricto is the primary mosquito vector responsible for the transmission of malaria in most of sub-Saharan Africa. It is a member of a species complex that includes at least seven morphologically indistinguishable species in the Series Pyretophorus in the Anopheles subgenus Cellia. An. gambiae feeds preferentially on humans and is one of the most efficient malaria vectors known.

The genome assembly presented here (AgamP4, April 2014) is a revised assembly based on the whole genome shotgun assembly of the PEST strain of Anopheles gambiae [1, 2], plus the addition of a mitochondrial chromosome. The assembly is described in detail in VectorBase.


Annotation of the AgamP4 assembly was carried out by VectorBase. The set of gene models presented (genebuild AgamP4.7, released August 2017) combines manual annotation, data provided by the research community, and gene prediction using the Ensembl system. Prediction utilised alignments of dipteran and other protein sets to the genome and generation of GeneWise models, alignment and gene prediction based on Anopheles ESTs, and selected ab initio predictions. More details can be found in VectorBase.


Variation data for Anopheles gambiae was imported from NCBI dbSNP, and from other studies involving the M and S molecular forms [3, 4, 5].

Variation data is also available for the Anopheles gambiae MR4 reference colonies 4ARR, Kisumu, Akron, L3-5 and G3. These samples were sequenced by the Kwiatkowski group at the Wellcome Trust Sanger Institute, as part of the Malaria Programme's Anopheles gambiae Genome Variation Project. These variants should be considered preliminary, pending further analysis and quality control filtering.
