SysTooth(Systems tool for Tooth gene discovery)

UCSC genome browser view of a ~2.5 Mb genomic interval containing MSX1, a gene associated with tooth agenesis and orofacial clefts. Using SysTooth tracks, we can readily visualize that MSX1 has the highest tooth specific expression among all the genes in this mapped genomic interval and therefore is identified as the best candidate for further analysis. MSX1 has now been associated with several cases of tooth agenesis.
