Isochromosome Yq in a woman with atypical Turner's syndrome.
A female with 46,X,i(Yq) in all cells and a survey of previous cases of isochromosome Yq is presented. She was first admitted to hospital 15 years old due to nanismus and retarded sexual development. Gonadal dysgenesia was observed, and the diagnosis 'atypical Turner's syndrome' was applied. The patient, who presents only a few Turner stigmata, has been given cyclic estrogen treatment since the age of 16. She has developed normal secondary sex characteristics, cyclic bleedings and has attained normal height (161 cm). Since the age of 18 the patient has suffered various periods of anemia caused by gastrointestinal hemorrhage. This hemorrhage is probably due to intestinal teleangiectasiae which are found with increased frequency in patients with Turner's syndrome.
