Ring chromosome 18 in a mother and son

M A Donlan et al. Am J Med Genet. 1986 May.

Abstract

Inheritance of ring chromosomes is reported infrequently. We report on a mother and her son both with a ring 18 chromosome, and describe the associated manifestations. The son had microcephaly, ptosis, short stature, and mental retardation; the mother was mentally retarded and had a similar facial appearance.
