Compositions and methods for the diagnosis and treatment of tumors of glial origin

A method of determining the presence of a type A glioma tumor in a human, said method comprising:

• (a) obtaining a test tissue sample from said human, wherein said test tissue sample is suspected of being a glial cell-derived tumor;
• and
• (b) detecting at least a 5 fold increase in the amount of at least 3 different type A antigens in said test sample as compared to normal adult human brain, wherein each of said at least 3 different type A antigens is encoded by a different DNA sequence selected from SEQ ID NOs:1, 2, 3, 4, 5, 8, 9, 11, 12, 18, 20, 21, 23, 26 and 28, and wherein one of the at least 3 different type A antigens is encoded by a DNA sequence selected from SEQ ID NO:8, SEQ ID NO:9, and SEQ ID NO:1,
• and wherein said detecting is indicative of said test tissue sample being a type A glioma tumor.
