All races and ethnicities are prone to the disorders and the risk can be higher if the parents are carriers since it is genetically inherited. Any of the 23 pairs of chromosomes can be ringed, and a recent study conducted by the 'Human Ring Chromosome Registry' in China revealed that the more frequent forms of ring chromosomes reported were 13,<unk> , 18 and 22.
