The five segmental duplications (LCR22-D to -H) at the distal region of chromosome 22 band q11.2 in the region immediately distal to the DiGeorge/velocardiofacial syndrome deleted region have been implicated in the recurrent distal 22q11.2 microdeletions. To date, the distal 22q11.2 microdeletions have been grouped together as a single clinical entity despite the fact that these deletions are variable in size and position depending on the mediating LCR22s.
