Furthermore, deletions were also observed in BID4, a gene associated with the cat eye syndrome, as well as genes outside of chromosome 22q11.2: PPP1R3B, MSRA, TCEB1P3, and RPH3AL. This is defined as a typical characteristic of molecular complexity which controls the 22q11.2DS phenotypes. The gene discussed is ELOCP3; the disease is cat-eye syndrome.
