Description

Detection of an abnormal chromosome clone is generally evidence of a clonal neoplastic process; rarely it may be associated with an unrelated congenital non-neoplastic abnormality. Certain abnormal chromosomes may also be associated with a morphological classification, however a normal karyotype does not exclude a neoplastic process.
