Abstract
In the course of re-examing cultured fibroblasts stored in liquid nitrogen from a patient with developmental retardation, solitary left kidney, and Wilms tumour, a cell line trisomic for chromosome 8 was found. Trisomy 8 was restricted to fibroblasts in the first 22 subcultures and was absent in later passages as well as in lymphocytes. A familial pericentric inversion of chromosome 2 was observed in three generations including the propositus but was though to be unrelated to the clinical problem. Multiple spontaneous chromosomal rearrangements were seen in several late subcultures.
