Allel-Specific Polymerase Chain Reaction (PCR) with capillary electrophoresis detection.
KIT gene mutations occur in approximately 25% of cases of acute myeloid leukemia (AML) with t(8;21) or inv(16), also referred to as core-binding factor AML. These mutations are predominately small length affecting mutations in KIT exon 8 and substitution mutations in KIT exon 17. KIT mutations in core-binding factor AML may be an adverse prognostic factor in this otherwise favorable-risk disease. This DNA sequencing test detects mutations in exons 8 and 17 of the KIT gene in blood and bone marrow specimens. This test will detect mutations in specimens when at least 30% of the nucleated cells carry the mutation.
