    A familial t(2q-;9p+) translocation in three generations is described. Three females were carriers and 5 members were partially trisomic for 2q. Ocular signs in the males, trisomic for 2q, included uveal coloboma, anterior chamber angle anomalies, congenital glaucoma with dislocated lens, exotropia, and blepharo-conjunctivitis.
