Genetic gain and loss in gliomas

A method of testing a sample for the possible presence of a glioma cell, said method comprising the steps of:

• providing a nucleic acid sample;
• and
• detecting, in said nucleic acid sample, an amplification or a deletion of a chromosomal region selected from the group consisting of an amplification in (1)(q21-23), an amplification in (1)(q32), an amplification in (1)(p36-pter), an amplification in (1)(p33-34.1), an amplification in (1)(p34.2-34.3), an amplification in (3)(q27-28), an amplification in (4)(p16), an amplification in (4)(q26-27), an amplification in (5)(p12-13), an amplification in (7)(p22), an amplification in (7)(q22), an amplification in (7)(q34-36), an amplification in (10)(q22), an amplification in (10)(q26), an amplification in (11)(q13), an amplification in (11)(q14-21), an amplification in (11)(q23), an amplification in (11)(p11.2-12), an amplification in (12)(p13.3), an amplification in (12)(p11.2-12.2), an amplification in (14)(q11.2-13), an amplification in (14)(q22-23), an amplification in (14)(q31-qter), an amplification in (15)(q13), an amplification in (15)(q15), an amplification in (17)(q24-25), an amplification in (17)(p11.2-12), an amplification in (19)(q13), an amplification in (19)(q13.4), an amplification in (20)(p11.2), an amplification in (20)(q13), an amplification in (X)(p22), an amplification in (X)(q27-28), an amplification in (Y)(p11.2-11.3), a deletion in (2)(p23-25), a deletion in (4)(q31.3-35), a deletion in (5)(q34-35), a deletion in (6)(q23-27), a deletion in (8)(q23-24.1), a deletion in (11)(q21-25), a deletion in (12)(q21-22), a deletion in (13)(q31-32), a deletion in (14)(q23-32), and a deletion in (21)(q21-22.1).
