    Gene mutationChromosome rearrangementEffectComments
    missense     mutation H1069Q(His 1069Gln), or Met645Arg, the most frequent in caucasians (30p100) causing mild form
    nonsense   abnormal protein/loss of function causing severe phenotypic expression (Leu 1120ter or Gln 111ter)
    abnormal splicing   unknown 1708-1G>A
    frameshift     associated with severe phenotype
    missense     C271 stop, prevalent mutation (19p100)
    Genotype/Phenotype correlations
  • frameshift and nonsense mutations are associated with a severe phenotype
  • missense mutation associated to milder form
