Fig. 1.
Map of 5′ flanking sequence and exon 1 of the MBL gene. The positions of the variable sites in the 5′ flanking sequences are shown as H/L, M/N, F/G, J/K, deletion -324 to -329, Y/X and P/Q. The positions of the structural variants in exon 1 at codons 52, 54 and 57 are shown. Consensus sequences for glucocorticoid-responsive elements (GRE) and a heat-shock promoter element (HSE) are present in the 5′ sequences.
