Anterior segment dysgenesis and congenital glaucoma associated with partial trisomy of chromosome 1 (1q32-qter).

A child born with partial trisomy of chromosome 1 (1q32-qter) survived and was seen for anterior segment dysgenesis and congenital glaucoma. Pure trisomy 1q is rarely seen in live-born infants and has not previously been described in association with congenital glaucoma. The genetic basis for glaucoma is complicated and multifactorial and probably determined by a number of genes on a variety of chromosomes. The current case provides some evidence that part of chromosome 1 may be involved with the etiology of a glaucomatous process.
