Trisomy 7 and Potter syndrome.
A patient with mosaic trisomy 7 and features of Potter syndrome is described. The patient was the product of a 35-week gestation and survived fourteen hours, demise being attributed to respiratory insufficiency. Autopsy confirmed pulmonary hypoplasia and renal agenesis. Additional findings included malformed, low-set ears, a flattened nasal bridge, redundant nuchal skin, positional deformation of the extremities, rocker-bottom feet, and clitorimegaly. Cytogenetic study of peripheral blood and skin fibroblast culture revealed mosaicism for full trisomy 7, the skin showing 12% of the cells to have an extra 7. Comparison with one previously confirmed case of trisomy 7 and two cases of trisomy C suggests a correlation between trisomy 7 and Potter syndrome.
