Abstract
FHIT located at chromosome 3p14.2 was discovered and proposed as a candidate tumor suppressor gene in several cancers. To determine whether the FHIT gene at 3p14.2 is altered in Chinese brain tumors, we examined 13 brain tumors for deletions within FHIT locus. Evaluation of the FHIT gene in the panel of brain tumors led to a comprehensive mutation analysis. The complete sequence of the FHIT gene was determined and deletions between exon 5-8 were found in all 13 cases. In addition, single point mutation of amino acid from two glioblastoma and one atypical meningioma cases and multiple amino acid mutations from one pituitary tumor were observed. Our results support the hypothesis that FHIT gene alteration is involved in tumorigenic development of human neoplasms.
