Clastogen-induced fragility may differentiate pancytopenia of congenital dyskeratosis from fanconi anaemia

Abstract
A male infant is reported with congenital dyskeratosis and pancytopenia Zinsser-Engman-Cole. The bone marrow pathology showed similarities to Fanconi anaemia. Ophthalmological complications were vitreous haemorrhage, haemorrhagic cataracta complicata and glaucoma. Spontaneous and diepoxybutane-induced chromosomal fragility was within the range of normal cells but was elevated through induction with 4-nitroquinolineoxide. These findings are contrasted with those of Fanconi anaemia.
