Fig. 6. Random monoallelic expression of FUT6.

Fig. 6

a FUT6 transcripts in basophils from the CD15shigh and CD15slow fraction. cDNAs from the CD15shigh and CD15slow basophil fraction of two CD15sbimodal individuals were isolated, and the region encoding for FUT6 amplified by PCR and sequenced. The upper panel displays the FUT6 sequence of the genomic DNA and the two cDNA regions covering three coding SNPs (rs61147939, rs145035679, and rs61739552). Each of the donors was heterozygous for two of these SNPs. Polymorphic bases are highlighted in red; base pair position as well as encoded amino acid residues are indicated. The histograms of the sequencing are displayed in the lower panels. Signals derived from polymorphic sites are indicated by red arrows. b ST3GAL1 transcripts. As a control, cDNA sequencing of ST3GAL1, a gene not known to be controlled by random monoallelic expression, is shown. The donor was heterozygous for rs1048479. Only the sequence proximal to this SNP is shown.
