Chromosome instability and X‐ray hypersensitivity in a microcephalic and growth‐retarded child
1 Jul 1991

We report on a microcephalic, growth-retarded newborn girl without major anomalies who has chromosome instability in lymphocytes and fibroblasts. Frequent involvement of bands 7p13, 7q34, 14q11, and 14q32 suggested the diagnosis of ataxia telangiectasia (AT) or a related disorder.
