title: Holoprosencephaly, ear abnormalities, congenital heart defect, and microphallus in a patient with 11q- mosaicism.
abstract: We report on a newborn male with deletion of part of 11q, the 27th reported case. Our patient had some of the clinical characteristics of the 11q- syndrome, but his male gender, liveborn status, q21 breakpoint, and mosaicism were unusual. In addition, he demonstrated holoprosencephaly, with cyclopia and arhinencephaly, manifestations previously unreported in the 11q- syndrome. We discuss the above points and review the literature on 11q-.
