We identified ten additional probands in North America, Europe, and the Middle East harboring monogenic microdeletions in ANKS1B through the Autism Speaks MSSNG project at the University of Toronto (TOR-1 and TOR-2), the DECIPHER project26 (DEC-1,2,4,5,8,9,12), and the GeneMatcher online resource27 (GEN-1) (Table 1 and Supplementary Data 2). The gene discussed is ANKS1B; the disease is autism.
