JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 503 OP 505 DO 10.1136/jmg.30.6.503 VO 30 IS 6 A1 Davidson, H R YR 1993 UL http://jmg.bmj.com/content/30/6/503.abstract AB A large family is described in which patent ductus arteriosus in association with an unusual facial appearance affected nine family members in three generations.

The facial features included a broad, high forehead, flat profile, and short nose with a broad, flattened tip.
