Band-Type Distribution

Graphical representations of the cytogenetic band distribution of the molecularly characterized breakpoints. The left-hand bar diagram shows the distribution in the Case group, and the right-hand diagram shows the Control-group distribution. R indicates R+ve bands (taken to be synonymous with G-light bands here). Cen or R/G indicates bands assigned as centromeric or existing at the junction between an R+ve band and a G+ve band. G1–G4 indicate G-dark bands, with G1 the darkest and G4 the lightest.
