Table 1 Major allelic types of msp1 block 2 determined by alignment of short reads to a library of reference sequences

From: An expanded global inventory of allelic variation in the most extremely polymorphic region of Plasmodium falciparum merozoite surface protein 1 provided by short read sequence data

Region Number Number (and %) of each allelic sequence type detected
K1-like MAD20-like RO33-like MR recombinant
Africa 2462 1119 (45.5) 618 (25.1) 610 (24.8) 115 (4.7)
Asia 1353 336 (24.8) 766 (56.6) 250 (18.5) 1 (0.1)
All 3815 1455 (38.1) 1384 (36.3) 860 (22.5) 116 (3.0)
  1. Short read Illumina sequence data for 2400 P. falciparum infection isolates in the Pf3k project were aligned to a library of reference msp1 block 2 sequences to determine the presence of each allelic type. Overall, 3815 alleles were scored in 2385 of the isolates. MR recombinant alleles were detected by the presence of a specific MR identifier sequence, and in infections where MR recombinant alleles were detected, additional presence of MAD20-like and RO33-like alleles was checked for by searching aligned reads for the respective non-recombinant 3′ and 5′ sequences
