abstract：:The FHIT (fragile histidine triad) gene at chromosome 3p14.2 spans the FRA3B fragile site and encodes for a diadenosine triphosphate hydrolase-type protein. FHIT is frequently abnormal in solid tumours including those of the upper aerodigestive tract (UAT) and has therefore been proposed as a tumour-suppressor gene. T...
