Cover: Worldwide distribution of MBL2 secretor haplotypes. Population codes are as reported in Table 1 in the accompanying article. Each secretor-haplotype segment in the pie chart (illustrated in different colors) is partitioned to reflect the internal degree of haplotype diversity. LYQB and HXPA are functionally uncharacterized haplotypes identified in this study. See Verdu et al., pp. 2650-2658, this issue, for further information.
