  1. Only the nominal results of the relevant exons are given, other exons are wild-type; for the individual panel labs only the actual results differing from the nominal results are denoted on DNA and protein level; matching results are not shown.
  2. a changes in DNA sequence were not specified in Labs B, C and E
