Filled coloured bars are UBCAs from peer reviewed papers; unfilled coloured boxes are from Abstracts only. Unfilled black boxes indicate alternative interpretations according to the authors concerned.

Figures in black give the number of times independent families with the same rearrangement have been reported (e.g. 4 etc).

Abbreviations: t indicates translocation, i insertion, m mosaicism in a parent and n the four exceptional Group 1 UBCAs that were not directly transmitted.
