“…DiGeorge Syndrome, alternatively called 22q‐deletion syndrome (22q11DS) or Velo‐facial syndrome, is a rare genetic deletion syndrome, caused by hemizygous deletion of the q11.2 part of chromosome 22 (Goldberg, Motzkin, Marion, Scambler, & Shprintzen, 1993; Swillen, Vogels, Devriendt, & Fryns, 2000). It is thought to be the most common microdeletion syndrome in man (Shprintzen, 2008), and is estimated to occur in 1 in 4,000 live births (Botto et al, 2003; Devriendt, Mortier, Van Thienen, Keymeulen, & Fryns, 1999; Oskarsdottir, 2004)…”
