Abstract:
Mutations in the intracellular juxtamembrane domain of the c-kit gene in 32 dogs with different grades of histologically confirmed mastocytoma were studied. Transcript RNAs extracted from neoplastic tissue surgically collected from dogs of different breeds and from a negative control were reverse transcribed into complementary DNA and amplified by polymerase chain reaction. The region corresponding to the c-kit juxtamembrane domain was sequenced and compared with GenBank sequences. Two different types of mutations were identified within exon 11: a previously underscribed single-nucleotide substitution and a 6-bp deletion. The c-kit juxtamembrane domain sequences of all dogs were grouped in 3 clusters. No mutations were detected in tissues constitutively expressing c-kit (cerebellum and spleen), obtained from dogs not affected by mastocytoma (controls). All the substitutions were found in dogs bearing grade I or II mast cell tumors; the deletion was detected in 1 dog with grade II mastocytoma.
