  • Exact position of GC site (beginning; end) is defined by its localization in acceptor gene relative to ATG. Distribution of GC acceptor sites relative to exon—intron structure of the genes is presented in Figure 2.

  • a CGB8 data are from the analysis of 11 Estonian individuals; the analysis of the rest of the genes is based on the combined sample set of 95 Estonian, Han, and Mandenka individuals.
