A systematic review on genetic diversity of var gene DBL1α domain from different geographical regions in Plasmodium falciparum isolates
2021, Infection, Genetics and EvolutionCitation Excerpt :The group A var gene mediates the adhesion of infected erythrocytes (IE) to uninfected erythrocytes, as seen in rosetting (McQuaid and Rowe, 2020; Vigan-Womas et al., 2008). The amino terminal of DBL domain is the most conserved in flanking region with highly diverse inner regions like DBL1α domain which has been the main target for various genetic diversity studies (Kyes et al., 1997; Ward et al., 1999). In this review we have compared the DBL1α diversity from different global geographic regions.

2008, International Journal for ParasitologyCitation Excerpt :The complete sequencing and annotation of the entire genome for the 3D7 isolate (Gardner et al., 2002), as well as additional sequencing projects for several other isolates, have shown that the var gene sequences possessed by any given parasite are extremely diverse, although certain subfamilies of var genes can be identified based on the structure of several domains within the encoded PfEMP1 (Lavstsen et al., 2003; Kraemer and Smith, 2003; Robinson et al., 2003; Kraemer et al., 2007). In addition, sampling of var gene repertoires from parasites isolated from geographically distant regions has shown that the diversity that exists when comparing the var gene complement between different field isolates is immense, suggesting that var genes possess a mechanism for creating sequence changes at an accelerated rate (Kyes et al., 1997; Fowler et al., 2002; Barry et al., 2007; Kraemer et al., 2007). This is in contrast to housekeeping genes which have been shown to be highly conserved between strains from different geographical regions (Jeffares et al., 2007; Mu et al., 2007; Volkman et al., 2007).
Malaria: a peek at the var variorum
2007, Trends in ParasitologyCitation Excerpt :It should be noted, however, that whereas these primers amplify DBL-α sequences from the vast majority of var genes, certain sequences, most notably that of the gene associated with pregnancy-associated malaria (var2csa), are not efficiently amplified using this strategy and thus must be considered separately [8]. To explore the complexity of the global var gene repertoire, Barry et al. obtained 895 DBL-α types culled from a global dataset of 1088 sequences (480 of the 895 DBL-α types were taken from the GenBank database), a much larger sample than available from previous studies [3–6]. Their parasite isolates differed not only geographically, but also temporally.
