In this mutation, a sequence containing six nucleotides, GGTGGC, was deleted at the intron-exon junction. It means that 1 nucleotide in 5'-end of 13 th intron and 5 nucleotides (GTGGC) in 3'-end of exon 14b (2619 to 2624) were deleted.
There were some differences in distribution in the European countries, but by far the most common mutation (35%) was at the intron-exon junction of exon 8, with p.trp151X (10%), p.thr95met (8%) and p.val326leu (7%).
(d) Primer annealing site is in intron 1; BC14 is numbered from the intron 1-exon 2 junction (the PCR product from BC14 and BC3 includes the intron-exon junction).
