Abstract
The present invention concerns a novel molecular marker useful for diagnosing hematopoietic disorders, including cancers and precancerous conditions. The invention is based on the unexpected discovery that inactivation of the IRF-1 tumor suppressor gene can occur via an altered splicing pattern of the IRF-1 primary transcript. This altered splicing pattern leads to mRNAs lacking exon 2 or exons 2 and 3. The relative amounts of full-length RNA and shortened RNA molecules are significantly different in samples obtained from patients suffering from certain cancers and precancerous conditions as compared to healthy donors.
