identified a candidate tumor suppressor gene, FHIT, at 3p14.2, by exon trapping experiment. FHIT is classified into the gene family HIT(histindine triad),and as the first common fragile gene to be found,it is easy to rupture.

 
  • FHIT基因是1996年Ohta等以外显子捕获法(exon trapping experiment)在染色体3p14.;2区定位的一个基因,属于组氨酸三联体(histindine triad,HIT)基因家族,因易于断裂,故命名为脆性三联组氨酸基因(FHIT),在染色体上占据1Mb大小的位置,覆盖FRA3B脆性位点。
