Background: Recurrent aphthous stomatitis is one of the most prevalent oral mucosal immunological diseases. A recent case-control study in the Egyptian population suggested that single nucleotide polymorphism Gly54Asp (rs1800450) of the mannosebinding lectin 2 gene might affect the mannose-binding lectin serum level and recurrent aphthous stomatitis development. The aim of this study was to determine the distribution of six functional mannose-binding lectin 2 gene polymorphisms and analyse their role in recurrent aphthous stomatitis susceptibility in the Czech population.
Methods:The study included 227 subjects; 137 healthy people and 90 patients with recurrent aphthous stomatitis. Six mannose-binding lectin 2 gene polymorphisms (rs11003125, rs7096206, rs7095891, rs5030737, rs1800450, rs1800451) were analysed by the SNaPshot assay method, mannose-binding lectin serum levels were determined by enzyme-linked immunosorbent assay (ELISA) method in a subgroup of subjects (N = 87).Results: No significant differences in mean of mannose-binding lectin serum levels between healthy controls and patients with recurrent aphthous stomatitis were Lydie Izakovicova Holla and Petra Borilova Linhartova should be considered joint senior author.
