Abstract: | Polymorphism of highly polymorphic triplet repeats CTG of the 3'-untranslated region of the myotonin protein kinase gene and CAG of the genes associated with dentatorobral-pallidoluysian atrophy (DRPLA, or Hew River syndrome) and spinocerebellar ataxia type 1 (SCA1) was analyzed in several ethnic populations of Russia. A difference in allele spectra of the three genes was demonstrated for populations differing in ethnic origin. |
