    Abstract:
    We report on 2 patients with de novo terminal deletion of 6q. The first was a 4-month-old boy whose karyotype was 46,XY,del(6)(q24.3); the second a 2-year-old girl whose karyotype was 46, XX, del(6)(q25.3). The main anomalies in both patients included mental retardation, minor craniofacial and cerebral anomalies, and cardiac defects. The characteristic manifestations were imperforate anus in the first patient, and retinitis proliferans and a triatrial heart in the other. Comparison of clinical findings of our 2 patients with those of 18 previously reported patients with similar phenotypes suggests that terminal deletion of the 6q23 or 6q25 band is critical in producing the main anomalies of del(6q) syndrome.
