PG - 351-4 AB - A 2-day-old infant was evaluated and suspected of having 22q11.2 deletion based on microcephaly, short and narrow palpebral fissures, a prominent nose with hypoplastic alae nasi, thin fingers, and a right aortic arch. He also had an imperforate anus, which is not in the del 22q11.2 syndrome. Karyotype analysis identified a ring 22, while fluorescence in situ hybridization (FISH) for the DiGeorge syndrome critical region identified a 22q deletion on the other homologue. The karyotype designation was 46,XY,r(22)(p13q13.3).ish del(22)(q11.2q11.2) (D22S75-). Both parents function in the mildly mentally retarded range. The father's karyotype was normal whereas the mother had the ring 22 that was inherited by her son. This is the first case reported for abnormalities on both 22 homologues.
