Figure 2. Decision tree to determine SLC44A2 alleles.

Figure 2

The computationally predicted haplotypes (alleles) were sorted according to 4 criteria. SLC44A2 alleles (confirmed haplotypes) need to fulfill at least one of the following criteria: 1) homozygous observation, 2) observation in at least 2 samples, 3) observed at least once heterozygously together with KM024996 and harboring only 1 SNP relative to KM024996 or 4) observed at least twice heterozygously together with KM024996. All other haplotypes were considered potential haplotypes requiring additional confirmatory testing. KM024996 is the prevalent SLC44A2 allele (wild type, see Table 1). Data is shown for all haplotypes computed for the 302 donors.
