When we evaluatedMBL2 polymorphisms singularly, the X allele and C/T genotype ofthe D allele associated with low MBP-C expression (Bouwman et al., 2006), were associated with increasedrisk of OLP development, as well as the MBL2 combined genotypes,and the fact that DP was more frequent in OLP patients than HP, which is more commonamong healthy controls, suggests a possible involvement of MBL2 insusceptibility to OLP development. The gene discussed is MBL2; the disease is oral lichen planus.
