title: [Polymorphic locus D6S392 near the Mn-dependent superoxide dismutase gene is associated with diabetes mellitus in the Moscow population].
abstract: OBJECTIVE
  Distribution of alleles of tetranucleotide microsatellite D6S392 located nearby the gene of Mn-dependent superoxide dismutase (SOD2) was studied in healthy donors (n = 143), patients with insulin-dependent (n = 166) and insulin-independent (n = 101) diabetes mellitus (IDDM and IIDM).
  
  
  METHODS
  Alleles of the polymorphic locus D6S392 were amplified using polymerase chain reaction (PCR) on the basis of genome DNA isolated from the venous blood of the examinees. PCR products were analysed with gel-electrophoresis in polyacrylamide gel. Significance of differences of allele and genotypes distribution in the population control and patients were assessed with Fisher's criterion and Bonferroni's corrections.
  
  
  RESULTS
  Locus D6S392 contains 31 allele from 210 to 330 pn in length and 37 to 67 tandem repeats. Compared to controls, IDDM patients had less frequent incidence of low molecular allele 41 and 42 as well as allele 62.
  
  
  CONCLUSIONS
  Polymorphic locus D6S392 is closely associated with development of DM in Moscow population. This may indicate possible participation of the gene SOD2 in development of this pathology.
