Homozygous deletions or loss of heterozygosity (LOH) at human chromosome band 3p12 are consistent features of lung and other malignancies, suggesting the presence of a tumor suppressor gene(s) (TSG) at this location.
ROBO1 (or DUTT1 (Deleted in U Twenty Twenty), FLJ21882, SAX3)
- ROBO1 (DUTT1), the human ortholog of the fly gene ROBO, has homology with NCAM proteins.
- Extensive analyses of ROBO1 in lung cancer have not revealed any mutations, suggesting that another gene(s) at this location could be of importance in lung cancer initiation and progression.
