mutation analysis
C-kit mutations will be assessed on existing paraffin-embedded blocks by Polymerase Chain Reaction and direct sequencing of both juxtamembrane domains (exons 9 and 11) and the tyrosine kinase domain (exons 13 and 17). Every ABI sequence will be compared to a NCBI Human KIT gene nucleotide sequence and will be blast using a NCBI Standard Nucleotide Blast Search to determine the presence of mutation within a particular exon.
